PYROLYSIS BOILER WITH UPPER LAYER FUEL COMBUSTION Russian patent published in 2017 - IPC F24H1/00 F24B1/00 

FIELD: heating system.

SUBSTANCE: pyrolysis boiler with upper layer combustion contains a housing, a fuel loading door, a loading hopper sealed on the top and bordered by a grate on the bottom, a heat exchanger located behind the loading hopper. At that, fuel combustion is performed in the hopper cavity. The air for fuel combustion is fed via ducts installed at different levels of the loading hopper and injected into the hopper using the nozzles installed in each duct. At that, flaps are installed before the nozzles in each duct. The air ducts of the charging hopper are connected to a collector located on the rear side of the boiler. At that, the air duct installed at the upper level of the hopper has a branch: one of the branches is connected to the collector, and the other - to the smoke exhaust channel, a flap is installed in each branch of the hopper air duct.

EFFECT: simplified design.
