At design of heating services for wooden house it is important to consider location of the house and possible connection to communications. At impossibility of connection to high-level networks the air heating services with use of the solid propellant boiler is applied. For blueprint stage it is necessary to make choice of the scheme of thermal contour and optimum power of solid propellant boiler.
Advantages and shortcomings of solid propellant boilers
The most important advantage of solid propellant boilers to the bar-shaped house – full independence of functioning. Residential building with solid propellant boiler does not demand special connection to communications and power supply networks. Boilers without application of water contour do not demand continuous burning. The applied fuel in such furnaces is normal the most inexpensive of all types of fuel.
In solid propellant boilers as fuel firewood, coal, peat, sawdust, pellets are applied.
It is possible to carry short time of burning on one loading of fuel to shortcomings, no more than 4 hours for standard boilers. Also solid propellant boilers need to be cleaned periodically from pitch and soot.
Heating charting
Whether the system will work correctly, depends on that as the scheme of heating will be made. It is correct to connect boiler perhaps only at correct installation of pipes and radiators. If to consider solid propellant boiler in the simplified option, then this device has only entrance and exit. On entrance and exit all system is also connected. For work of heating services on the basis of solid propellant boiler with the maximum return it is necessary to meet the following conditions: temperature of boiler cannot be less +55os, and water temperature in the return boiler is less +45os. Life cycle of boiler decreases in connection with condensation of vapors of water on boiler walls. It is possible to adjust this phenomenon by means of various schemes of heating services. All scheme of connection has to conform to requirements of opening systems of heating. Exit of combustion products has to happen through flue to natural draft and installation of broad tank has to be planned in the top point of contour. The most widespread scheme – connection of solid propellant boiler with use of the roundabout bridge. Also schemes of connection by means of metering pumps, with use of water communication, with heat-sink capacity and the four-way valve are used.
Optimum schemes of connection are recommended by the producer in the passport of solid propellant boiler.
The project of heating services has to provide speed of heating of rooms to the established indicators, stability of these indicators, coherence of work of knots and accessories of system. In all schemes the basic principle is replacement of the cold heat carrier hot. The overall performance of solid propellant boiler depends on the chosen scheme and quality of assembly of all heating services. Qualified specialists have to make the choice of the scheme of heating services and installation of heating contour.
