Modern apartment building - is a complex set, whose task is to ensure domestic needs of its tenants and residents. From the level of technical equipment of a residential home comfort depend on the inhabitants, the level of livability. A leading role in this respect plays a heating system, which not only has to ensure heating the interior in the cold season, but also to ensure that the work of hot system water supply. For a country house, in the absence of a central gas supply issues with the heating and hot water supply operation can solve the double-pressure boiler for solid fuels.
Let us consider in more detail what constitutes a similar technique.
The expediency of installation in an apartment building a solid fuel boiler
This type of heating equipment is very convenient for those dwellings where there is no centralized system of gas supply. With electrical heating recognized today are not effective due to the high cost of electricity, so it is often used only as an aid. Solid units on the contrary, are able to run on fuel, which at times is at hand. It can be wood, wood waste, coal. Solid fuel is available in sufficient quantities, will not only ensure a permanent boiler operating load, but also bring substantial savings in home budget.
Presented today in the sale of solid fuel boilers single-circuit and double-circuit - is a device with a high technological characteristics. This technique is now manufacturing companies brought to perfection. A number of design innovations have substantially improved the efficiency of boilers has changed for the better conditions of service of heating devices for solid fuels. Turbofan boiler solid fuel copes with heating of an apartment house in the cold season, at the same time giving to the residents for domestic use hot water.
Technological progress does not stand modern technology in place. Demand creates supply. Even yesterday, are unpopular boilers working with wood or coal, are becoming popular again. The intensity of suburban housing has become one of the reasons that the solid fuel heaters again in value. People mass establishes heating units for domestic heating systems, which are used as fuels and fossil organic materials.
Turbofan solid fuel boiler long burning - the best solution for heating private houses. Powerful unit providing all accommodations sufficient amount of thermal energy is also very economical and easy to maintain heater. Especially that such heating devices require little human intervention.
The combustion of fuel, pledged to the boiler, there is a long time, freeing the tenants from having to deal with constant tossing of the fuel material. It is a long process of combustion and makes this technique maximum attractive to the consumer. Not everyone wants to be a fireman, and stand in the cold winter nights near the furnace, throwing up in the boiler wood or coal. The principle of action underlying the operation of equipment, and gave them a name - long burning boilers, solid.
The principle of operation of this type of heating equipment
Various materials have been much said about what is based on the principle of heating a solid-art continuous burning. The achieved effect is due to a fundamentally different method of burning fuel in the combustor. Due to the multi-stage combustion process, ensures complete burnup fuel mass loaded in the boiler. This releases a large amount of wood gas, which carries out the bulk heating of the coolant.
For reference: units operate on the basis of the pyrolysis, the generation of volatile inflammable compounds obtained from the wood as a result of exothermic reactions. In the process of decay of fuel wood is formed (pyrolysis) gas which is ignited in contact with hot air. This technique is also called gas generators.
The principle of action of the boiler equipment relative concept, we shall understand how the double-autonomous solid fuel boiler in the home. Consider its main features. The presence of a system of two loops provides heating and hot water in the house. In the first loop circulating boiler water which diverges across the conduit, supplying heat radiators. The second circuit for removing the waste destination coolant back to the boiler for further heating. Installed on both circuits sensors - determinants sensitive to the slightest change of a given coolant temperature, giving signals to the control panel. Accordingly Automatic actuates a mechanical device that regulates the flow of air into the combustion chamber of the heating appliance.
Design features dual-model
With a double load, heating and hot water, solid units of this type are equipped with additional devices. There are two types of such devices:
- storage heater (heat accumulator);
- an additional coil.
The difference in both devices is the principle of heating water. In the first case we are talking about the storage tank, which accumulates hot water and hot water from there diverges to the connection points. In the second case, cast iron hot water coil is installed inside the boiler. Heated water is in a mode of constant circulation of hot water. Both options are equally successful and effective, to ensure a steady supply of hot water the tenants of the house. Together with a boiler heater does not take much space, but the presence of two circuits required to observe certain rules during operation of these devices.
Wiring diagram of a bypass solid fuel boiler about looks. By design, all heating devices of this type are almost identical, except for a few differences.
The only condition: when connected to a heat storage system it is necessary to have strict control over the use of hot water. Installation of more than two connection points of the hot water in the house may adversely affect the hot water system efficiency. Instantaneous hot water preheating method is more dynamic in terms of operation, but when this boiler power should be significantly higher.
Combi boilers prolonged combustion are of standard design, which in many models is practically the same, except for some differences.
The figure shows the standard design of the solid unit working on heating and hot water systems.
Solid fuel boilers with two circuits comprise:
- basic, thermally insulated housing;
- a combustion chamber (fuel);
- podzol chamber (ashpan);
- primary heating system heat exchanger;
- an additional heat exchanger (coil) for hot water;
- automation and control devices;
- damper and chimney.
In some cases, the circulation pump is additionally installed, which provides forced circulation of coolant mainly heating circuit. For best performance, long burning heater fans are used, the air is injected into the combustion chamber and contribute to a better outflow of combustion products through the flue.
Some nuances in the combi boiler for solid fuels
The obvious advantage possessed by the solid fuel boilers of this type - continuous operation when unit loaded with fuel.
For example: 30-50 kg. wood laid down in the furnace can burn up to 12 hours. The unit for this time able to provide the maximum possible heat for home heating in the house and ensure the normal domestic hot water requirements. hot water savings will increase the duration of combustion to 24 hours. The boiler will operate at rated speed by maintaining a certain temperature in the building.
It should be remembered! Dormant for long periods during the winter is solid unit can cause freezing of the entire heating system. To avoid such troubles, it is possible for the main heating circuit antifreeze.
Also important that combi boilers long burning does not allow exercise with high precision adjustment of the coolant temperature in the heating system. The reason lies in the complexity of the inertia running of the heating equipment. Built boiler will solve this problem by creating optimal conditions for control of the heating unit.
In conclusion a few words about where and how the house is better to put this heating equipment. long burning boilers for solid fuels, are produced only in the outdoor performance. View of the complexity of the design and the need to install storage tank, the best option would be a special boiler room equipment.
