Solid fuel boilers are customary to the category of heating equipment, which is intended for functioning in non -stamped regions. In addition, their operation is considered justified in the absence of electricity and liquid fuel.
Today, approximately 22% of the heating equipment market belongs to such installations. Solid fuel boilers Viadrus are considered quite popular among them. The main consumers of heating solid fuel equipment are considered to be residents of the private sector. They use, in most cases, equipment of minor power, 35–90 kW. The operation of solid fuel boilers is justified from an economic point of view, despite the fact that liquid -fuel equipment guarantees a larger utility coefficient and releases a relatively smaller number of harmful substances.
Traditionally, solid fuel boilers work on a slope, coal, firewood, coke, peat briquettes and pellets. Separate attention is deserved by gas generating (pyrolysis) solid fuel boilers. They use, with the exception of solid varieties of fuel, gas, which is released in the process of burning. These models are slightly superior in effectiveness only Beretta gas boilers.
Modern heating installations on firewood have a relatively small useful coefficient, approximately 75–85%. It is worth noting that the heat -intensive abilities of different fuels are unequal, for example, the heat of firewood is less, in comparison with the coal and such a parameter is required to take into account the furnace of the boiler.
Fuel boilers are not capable of functioning in absolute automatic mode, which provides for the need for periodic constant loading of a particular fuel (for coal every six to eight hours, for firewood-two to three hours). The process of burning solid fuel is weakly adjustable, which affects the accuracy of maintaining a certain temperature regime for heating the room. To date, forming solid fuel equipment, leading manufacturers seek to remove such shortcomings, guaranteeing high efficiency, reliability and safety.
