One of the best ways for providing housing with heat and comfort - installation of solid propellant boiler. Their main advantage – the total non-volatility. That the heating system worked fully and smoothly, it is necessary to install the boiler correctly.
General characteristic of solid propellant boilers
Heating by solid fuel finds broad application in owner-occupied dwellings and industrial facilities. Distinctive feature is that on the basis of solid propellant boiler it is possible to create unerthed system of heating which does not depend on any communications. For such heating system only coal, firewood, peat briquettes or other solid fuel are necessary. Solid-fuel boiler – great option for providing with heating and hot water of the object which is in the area in which there is no centralized supply with gas and electricity. Heating by solid fuel in those places where it is generally available is favorable.
One of minuses of the solid propellant boiler house is that it has limited possibilities of automation. The longest term of operation of such boiler at one laying of fuel is about three days on coal and day for firewood. It creates need to periodically control availability of fuel in fire chamber and process of burning. The boilers working at wood granules (pellets) have no such shortcoming, but their operation requires electricity. Therefore the heating services with such boiler is not completely autonomous.
Sometimes solid propellant boilers use as reserve source of heat in areas with available electricity and gas.
Main requirements to installation of solid propellant boilers
For safe operation of solid propellant boiler and efficiency of heating system, it is necessary to fulfill the following requirements: - under the boiler house it is necessary to allocate the certain room with area not less than seven square meters; - in the boiler house there has to be the plenum ventilation; - floor in the boiler house it has to be covered with non-combustible materials; - distance from boiler to walls there has to be not less than a half of meter; - parameters of flue have to answer boiler power; - it is impossible to store flammable materials in the boiler house. At installation of boiler it is necessary to pay attention to its power and performance, to the fuel necessary for its work. And also to choose the place in which it will be stored.
Stages of installation of solid propellant boiler
The place chosen for installation of boiler should be flooded with concrete tie which thickness has to be at least seven centimeters. The lower part of boiler and tie have to adjoin densely among themselves. If between them gaps are formed, fill in them with heat-resistant sealant. For high overall performance of heating services it is necessary to combine installation of solid propellant boiler with connection of buffer capacity (tank with water). Its volume is selected depending on the power of the boiler. Capacity cuts fuel usage, accumulates heat, protects boiler from overheating. The top point of heating system is suitable for installation of tank. On outlet pipe between the capacity and boiler it is necessary to establish safety lines, they connect in the short way boiler and tank. On these lines it is impossible to install any valves and cranes. At installation of volatile solid propellant boiler it is necessary to think over connection it to network. Most often supply with the electrical control panel and the fan which supplies with air the combustion chamber gas-generating boilers.
The first protaplivaniye has to occur under the leadership of the expert who also has to check heating system regarding tightness.
As operation of the solid propellant boiler is followed by smoke, soot, soot, the flue for heating system on it is indispensable condition. Establishing flue, in it insert protective insert from stainless steel. The lower part of pipe is equipped with the collection of condensate. The part flue located on the attic needs to be heat-insulated. Once a year the flue should be cleaned surely, for this purpose in several of its places leave openings. It is impossible to attach other heating appliances to flue. To avoid effect of reverse thrust, street part of flue in height has to be more than a meter from roof ridge. The pipe diameter has to be not less than eighteen centimeters.
Having begun operation of solid propellant boiler, it needs to be examined regularly. Having found any malfunctions, it is necessary to address experts for their correction.
Mounting of solid propellant boiler is impossible without protection of heating services against siphon drainage and back pressure. For this purpose install the back valve on pipe of the general water supply. For regulation of liquid in the heat exchanger, the scheme of connection provides the balancing valve. To exercise control over heat carrier temperature in the return contour, install the mixing valve working in the autonomous mode.
