Operation description of hot water boilers for solid fuel based on plants «Whirlwind»

Industrial hot water boiler based on the plant “Whirlwind” consists of the plant “Whirlwind”, heat recovery boiler “KU”, smoke exhaust and pump.

Under high temperature and air insufficiency in the loading chamber (furnace) of the plant “Whirlwind” the solid fuel splits up into synthetic gas (combustible gas). The synthetic gas comes into combustion chamber to be mixed with additional (secondary) air, inflames and burns in turbulent flow under 1300°C.

During combustion of synthetic gas due to high temperatures the process of afterburning of all unburnt fuel particles is going on that prevents formation of carbon deposits (soot), lowers the ash formation 2-3 times and reduces fuel consumption 2 times, according to the practice of boiler use.

The effluent combustion products of synthetic gas of 1100-1300°C under rarefication due to smoke exhaust are directed in the heat recovery boiler “KU”, where the energy of effluent gases (heat) are transferred to the heat carrier (water, thermal oil etc.), which circulates in the heat-exchange case of the recovery boiler by means of the pump. The effluent gases, having transferred their energy to the heat carrier, come through the smoke flues in the chimney, and the heat-carrier, having got the thermal energy, enters the heating system or is used for other intended production needs.
