DIY decorative false fireplace
Building a false fireplace is a time consuming process that requires some skill and experience in construction. To build a beautiful and reliable structure that will serve without deformation for a long time, you should correctly draw up a drawing, calculate the amount of consumable materials and carefully study the step-by-step guide.
How to make a drawing and choose the right parameters
When creating a drawing of a fireplace structure, it is necessary to take into account both the size of the room and the future decor element. The classic floor-to-wall oven has the following parameters: the width of the lower part is 1500 mm, the depth is 345 mm, and the width of the upper part is 1490 mm.
What materials will be required
Depending on the type of fireplace, you will need to prepare a number of materials and tools for their processing. If we are talking about a drywall product, you need to buy sheets of drywall. When choosing a material, you should be guided by the characteristics of the facing layer. When finishing with a slab, it is necessary to consider the option of a moisture-resistant modification. Then you need to buy support profiles, on the basis of which the fireplace frame will be assembled.
To connect the frame elements, you should purchase self-tapping screws. The optimal length of the fasteners is 1.4-1.6 cm. You should also prepare countersunk head screws - with their help, the sheets will be fixed. You will also need dowel nails to attach the profiles.
The amount of consumables is determined by the size of the decorative structure.
Polyurethane fireplace
The option of erecting an artificial hearth made of polyurethane is one of the most affordable and fastest. For the upcoming work, you will need to buy a polyurethane portal, calculate the dimensions and perform the installation.
If you are using an electrical device with a picture of fire on the screen, you should measure it from all sides, and then create a wireframe based on the obtained data.
It is also important to provide for ways of connecting to the electrical network and the reliability of the ventilation system.
Plywood construction
Plywood portals are especially in demand when hiding any defects in a room, including an old heating battery. To create a frame, you should use wooden blocks, and then sheathe it with plywood.
The appearance of the fireplace is determined by personal preference and the style of the interior.
Imitation of a plasterboard fireplace
It is more difficult to build a decorative hearth based on drywall than using other materials. But in conditions of limited space, a corner plasterboard option may be the most optimal. To create a frame, a thin metal profile is used, in which holes are made for dowels or self-tapping screws. Then drywall is attached to the base, giving it the required shape.
New life of old furniture
An affordable option for creating a decorative fireplace is to transform old furniture. If the house has an unnecessary cupboard or sideboard, you should not throw it in the trash. With minimal imagination, you can make a good imitation of a fireplace stove out of this piece of wood.
Stages of work
To simplify the process of erecting a false fireplace, it is necessary to study the sequence of actions and get to work. You will need to prepare drawings and calculations, then collect the necessary materials and tools, start creating a frame
Further, it is important to provide for a communication connection diagram and perform the decorative part of the work
Areas of application of the material
Before making a fuel briquette with your own hands, you need to figure out where it can be used. Most often, the material is used for heating residential buildings, educational institutions, and catering establishments.
In addition, fuel briquettes can be used in warehouses where wood materials are dried and stored. Industrial enterprises also often use the presented type of fuel in combination with other materials. In any case, the presented material is the most efficient and economical, especially in comparison with other types of fuel.
What raw materials are used in production?
Before making a fuel briquette with your own hands, you need to select the necessary source material and equipment. First, let's figure out what the product can be made of. So, most often wood and plant waste is used in production.
For example, you can make a briquette at home from vegetable husks, sawdust, and straw. In addition, it is also allowed to use for production such materials as fallen leaves, shavings, dry plant stems, chips, seed husks.
Naturally, for production, you also need water, clay and other substances that can glue the raw materials. In some cases, starch can be added. In general, you can use any combustible waste that is uselessly lying on your territory for making briquettes.
Applied equipment
In order to make a fuel briquette with your own hands, you need to choose the right press or chipper. When choosing a press, it is necessary to decide what shape and area the elements will have. Most often, round and rectangular briquettes are made.
Among the professional equipment, one can distinguish a screw, impact-mechanical and hydraulic press. The first device is capable of delivering octagonal elements with a small hole in the center. They are distinguished by their maximum density, therefore they provide the longest burning time. The hydraulic press produces rectangular elements with the lowest density, which ensures high material consumption. Making fuel briquettes at home using a shock-mechanical device gives you the opportunity to make material of any shape. Moreover, the elements have an average density.
You can make a machine for making briquettes at home. To do this, you need a simple press and mold (sewer pipe with drilled holes). Please note that during the manufacture of the presented product, you will need to take into account the length of the firebox.
Pellets: what is it and how is it made
The modern type of fuel that is used for combustion in pellet boilers Pellets at the moment are an excellent alternative to gas and other fuels, but many do not know what it is. Heating with pellets is 3-4 times cheaper than gas, but so far the technology of manufacturing such material does not make it possible to completely replace gas with it. But many people consider pellets as an alternative. Contents What are pellets? History of appearance Environmental factor Classification of pellets Production process Fuel advantages How to choose high-quality pellets?
Pellets are considered an environmentally friendly fuel
Shredded wood used to make pellets
One of the characteristics of fuel pellets is the amount of heat energy released, which affects the cost of raw materials.
Wood pellets in a vessel near the boiler create a kind of decor in a modern interior
Pellets: what is it?
Externally, fuel pellets look like cylindrical granules. Waste of wood and agricultural production is pressed into them. Their sizes are standard: Diameter - 6-8 mm. Length - from 5 to 70 mm. Humidity - 7-10%.
"Loose" granules are convenient when using feeding devices in boiler houses. Due to this indicator, they are successfully used in pyrolysis boilers. If we compare it with firewood, then the efficiency of boilers using such fuel is 1.5 times greater. But the size of one pellet depends on the material used for the production, the type of raw material and the scope of use. Note!
Abroad, this type of fuel is actively used, especially for automated boiler houses. Pellets have found their distribution both in domestic and industrial use. In terms of their thermal conductivity, pellets are compared to coal. In addition, this fuel is environmentally friendly.
Well-dried pellets work more efficiently
History of appearance
Pellet boilers were first used in the USA, and it was there that the production of this material started. Although initially the idea of pelleting was somewhat different, because in this way it was planned to save space when transporting waste. But rather quickly, pellets began to be used as fuel. In Europe, for the first time, alternative fuels were discussed in Switzerland in the 1980s. Pellets begin to be made from wood waste. In the 90s, a real boom in the production of fuel on an industrial scale developed in Switzerland. Further development took place in Canada, Denmark, Finland, England, Italy. At the moment, the plants for the production of pellets are located directly next to the logging and timber processing enterprises. This allows fuel production to continue, and such factories often operate 24 hours a day.
Environmental factor
Buying pellets means maintaining a stable ecological background. They are the result of waste processing, which means they will not harm the atmosphere and humans. It is believed that pellets are part of the CO cycle in the environment, that is, they release it exactly as much as the tree absorbed during growth.
In the process of burning pellets, the same amount of carbon dioxide is emitted as formed during the natural decomposition of wood Note!
Waste is used in the production, which means that each ton of such fuel keeps the trees in the forest safe and sound. And the environment is not polluted by wood processing waste. What is very important, the emissions into the atmosphere from the combustion of such fuel are not as harmful as if coal and diesel fuel were burned.
The chemical characteristics of pellets depend on the raw materials from which they are made.
Pellet classification
The price of pellets largely depends on the raw materials used in the manufacturing process. There is such a classification:
A variety of pellets based on raw materials White pellets - this grade is also called “premium”. They are made from wood waste without bark. The calorific value of such pellets reaches 17.2 MJ / kg. The ash content is practically zero. Such pellets make up about 95% of all that are on the market today. They are suitable for all types of boilers.
The advantage of white pellets is low ash content. Cleaning the boiler after such raw materials is necessary no more than once a month Industrial - they contain wood of lower quality. In addition to wood waste, they may contain bark and non-combustible particles. In terms of calorific value, they hardly differ from the first type, but the ash content is slightly higher. When using them, the boiler will have to be cleaned more often.
Additional elements in the composition of industrial pellets make their color a little darker Agropellets - they are made from agricultural waste. Their calorific value is lower - up to 15 MJ / kg, ash content is more than 4%. That is, the boiler will have to be cleaned often. Among the advantages of such fuels is their affordable price. They are used mainly for generating heat in large thermal power plants. They are also convenient if the boilers are equipped with automatic ash removal. They can be used not in all boilers, but only in those that are designed for such a fuel.

Manufacturing process
Pellet production is a multi-stage process that requires both material and time costs. But first of all, raw materials are delivered to the plant. Raw materials can be: Bark, sawdust, wood chips, other logging waste. Agricultural waste: corn, straw, sunflower husk and others.
Pellets for heating boilers from sunflower husk The technological process of production consists of the following stages: Coarse crushing. Drying. Fine crushing. Mixing and water treatment. Pressing. Cooling, drying. Packaging.
Waste wood chips are used to make wood pellets
Primary crushing
It is also called coarse crushing. In the process, grinding takes place to a size of 25 x 25 x 2 mm. This process provides fast drying of raw materials to the required moisture content. Since such material is stored on a concrete floor to avoid mixing with sand and stones, it is fed to the grinder by means of a scraper device.
Shredding wood waste - the first stage in the production of pellets
Drying
Now the raw material has a moisture content of 15%, which is not suitable for the next stages, since it will be poorly pressed. And pellets that contain so much moisture are not suitable for boilers. The optimum moisture fork is 8% to 12%, but correct pellets are 10%. In order to dry the primary crushed raw materials, drum belt dryers are used. The choice of this or that drying method depends on the type of raw material, its quality and other factors.
Raw materials for the manufacture of pellets with inappropriate moisture require additional moistening or drying Note!
This process is energy-intensive, because in order to dry 1 ton of raw materials, at this stage, you need to burn 1 m³ of firewood. In order to reduce the cost of this process, bark or sawdust is burned to the furnace of the dryer.
Secondary (fine) crushing
In order for the press to work, the size of the particles should not be more than 4 mm, therefore, re-grinding is applied. For this, hammer mills are used, which are excellent for crushing fibrous shavings, sawdust.
Sawdust prepared for re-crushing
Water adjustment, pressing
Since at the previous stages the raw material was dried and at the moment it has only 8% moisture, it will be difficult to glue it together. For this, the material is moistened with water or steam.The latter is necessary when pressing solid wood waste. If the raw material is softwood, then additional moisture is sufficient. As for pressing, the equipment for pellets has different forms of the matrix - flat and cylindrical. The diameter of the matrix itself is about 1 meter, while the power is measured at 500 kW.
Some manufacturers' presses do not require additional steam due to their design features.
Cooling, packing
In order to obtain quality pellets, it is necessary to cool them well. This process helps to drain the granules. After the press, they have a temperature of + 70-90 ⁰С. After completing this process, they are sieved and packaged. Since pellets are loose raw materials, they are often stored in bulk, but this can negatively affect the quality of the material, as it picks up moisture. Therefore, manufacturers pack and recommend storing fuel in large big bags. The best quality pellets you can buy are pre-packaged from the factory in 20 kg bags.
The packaging of granules depends on the storage system existing at the consumer: in bulk, in big bags or in small packaging
Fuel advantages
Pellets have a number of significant advantages: It is an environmentally friendly raw material that does not produce increased CO2 emissions into the atmosphere. Low risk of spontaneous combustion due to the fact that they do not contain spores, dust. Pellets are denser than wood and their moisture content is lower, which provides more heat from combustion of the same volume as wood. Due to the standard dimensions and flowability, it becomes possible to completely automate the heating process. The most common types of pellets have little waste, which means that you do not need to clean the boiler every day. According to the reviews of those who use this fuel, cleaning is required no more than 1 time per month. Only at first glance, this fuel does not seem to be the most affordable. In fact, if we recalculate the amount of heat energy, then it is the pellets that will be the most efficient fuel in this regard. Ease of storage of raw materials - minimum space and no odor. Simplicity and cleanliness of transportation. High boiler efficiency within 96%. An example of the operation of a pellet boiler in section Note!
If we talk about the shortcomings of the material, then this is the need to constantly keep stock in the warehouse. Also, as a disadvantage, the danger of burning pellets is noted if the raw materials from which they were made are taken from areas contaminated with radiation. Indeed, there is such a risk, but manufacturers who have been on the market for a long time will not risk their image and sell frankly dangerous material. Therefore, you need to carefully choose the manufacturer of the pellets.
Wood pellets are practically not susceptible to spontaneous combustion, since they do not contain dust and spores. In addition, they do not cause an allergic reaction.
How to choose quality pellets?
The importance of choosing high-quality pellets is that only such pellets can provide the declared amount of heat. The parameter of their ash content will also be within the presented limits. The use of low quality fuel leads to accelerated wear of the boiler.
Pellets provide a high calorific value compared to wood chips or wood. When choosing, you need to pay attention to: Size. Moreover, not only the dimensions of the pellets themselves, but also the presence of broken and crumbled ones. There should be no dust in the package, and if it is found in significant quantities, then it is not worth buying such fuel. The surface of the pellet must be smooth and shiny. If the material is of poor quality, then roughness will clearly be noticeable. Pellets must be firm and dry, only these should be used. It is difficult to break a high-quality pellet; in no case should it crumble in your hands. Another way to check the quality is to throw fuel into the water, and if the pellet sinks, then this is good, but if it floats, then it is better to look for another fuel.
The correct shape of the pellets allows them to be easily transported and handled, as well as to pour through special sleeves. The use of pellets is a convenient and environmentally friendly solution. It is not surprising that almost all of Europe has already switched to such fuel.
Fuel briquette refers to alternative types of fuel that are used to speed up the ignition of the stove or replace the wood in the fireplace. In addition, briquettes are widely used for heating greenhouses, garages of summer cottages or garden houses for temporary residence.
Modern technologies make it possible to obtain briquettes from unnecessary materials and waste.
The main advantages of fuel briquettes include:
- The ability to make fuel briquettes with your own hands
, and in the presence of simple adaptations, their production can be organized as a way of running your own business. - Compared to wood
- Longer burning time, with minimal sparking and smoke formation. - Ecological cleanliness
, since in the production of briquetted fuel, plant waste is mainly used. - Economical briquettes
in comparison with coal or wood, it is explained by the use of waste and the use of their muscular strength and the simplest devices; - Waste-free use
- ash formed after combustion can be used as fertilizer. - Practicality, unpretentiousness and economy during storage
- stacked briquettes take up less space than loose firewood or coal. - Can be used in any heating system
and devices, ranging from a summer cottage fire and ending with a boiler for an individual heating system that runs on solid fuel.
Material manufacturing technology
The production of fuel briquettes consists of several stages:
1. First you need to grind the waste that will be used for the production of elements.
2. Add dry clay to the same container, which will serve as a connecting link.
3. Now add water to this mixture. Moreover, the gruel should not turn out too liquid or thick. In any case, the mass should be well molded. In addition, the density of the briquette depends on the amount of water.
4. The resulting mixture must be poured into a mold and flattened with a press. Make sure that as much water as possible comes out of the gruel. After that, the resulting products must be thoroughly dried in the sun. In order for them to be durable, each element should be covered with paper or rags. Once completely dry, all the briquettes can be folded together.
When you press the raw material with a press, you will have to put in a lot of effort to squeeze out as much water as possible from the mixture.
Waste briquetting device
Homemade press
In the event that it is supposed to use heating briquettes for winter heating of a country house in winter or as an alternative fuel in an individual house, it is rather laborious to make them manually.
In this case, it is advisable to make the simplest machine that will speed up and facilitate the work. Today, various modifications of the machine tools are available on the market. They differ in functionality, the number of cells in the forms, and the type of drive - manual or mechanical.
All models have one thing in common - they allow mechanizing the most laborious process - the compaction of the wet mass in the mold cells.
The simplest machine is a metal frame welded from a corner, on which a wooden tabletop painted with moisture-resistant paint is fixed. A "P" -shaped bracket is welded to the frame, between the posts of which a swinging lever is fixed - a rocker arm, the length of which depends on the compression force.
A punch is hinged on the lever, the dimensions of which are slightly smaller than the dimensions of the cells. The mold, filled with the briquette mass, is placed on the table top and pressed with a punch until the briquettes are given the desired density.Moving the mold over the countertop, the crimping operation is repeated for each cell.
In order for the press to serve long enough, after each pressing operation it should be cleaned of the adhering mass.
If the gardener has the opportunity to get or make a vibrating plate, then the press is not required. Compaction of the sawdust-clay mass is carried out by vibration.
Useful Tips
Do-it-yourself production of fuel briquettes is quite simple, although laborious. Please note that the moisture content of each product should not exceed 13%. In order for the element to burn better, during manufacture, you can add paper, which needs to be torn into small pieces. And so that all the constituent parts stick together better, you can add a little starch to the mixture.
Please note that you will need different briquettes for different types of heating devices. For example, peat and birch elements are well suited for fireplaces. For baths, saunas and barbecues, it is better to use eurowood or wood briquettes. They can both burn and smolder slowly. In addition, they practically do not emit any carcinogenic or other harmful substances.
Now you know how to make a fuel briquette with your own hands. Good luck!
