HOT-WATER SOLID-FUEL "BLAGO" BOILER Russian patent published in 2011 - IPC F24B1/183 

FIELD: power industry.

SUBSTANCE: hot-water solid-fuel boiler includes body, fuel filling silo, air-gas passage, heat exchanger located in air-gas passage, furnace chamber, air supply mechanism to furnace chamber. Air-gas passage consists of inner walls at least of two vertical filling silos located along the perimetre of air-gas passage, and external walls are the part of external wall of the body; furnace chamber is installed under air-gas passage. At that, air supply mechanism to furnace chamber consists at least of one nozzle located under each one at least of two vertical filling silos, with direction of air flow at a tangent to lower bed of solid fuel, which is located in vertical filling silo, and air flow is directed into furnace chamber.

EFFECT: activation of thermochemical decomposition process of hydrocarbon material into generator gas and solid residue with their more complete combustion in the medium containing excess air oxygen.
