BOILER FOR CHARCOAL BURNING Russian patent published in 2012 - IPC C10B53/02 C10B47/00 C10J3/20 

FIELD: power engineering.

SUBSTANCE: boiler for charcoal burning comprises a vessel 1, a loading hopper for firewood 2, a gas duct for combustible gases 3, a combustion chamber 4. The gas duct 3 is formed with inner walls, at least two tight loading hoppers for firewood 2, which are arranged along the perimetre of the gas duct 3, and the outer walls are the part of the external wall of the vessel 1, the combustion chamber 4 is installed under the gas duct 3. The loading hoppers for firewood 2 are connected with the combustion chamber 4 by a channel 7 entering into its ashpit 5, through which combustible gases released from firewood pass. In the gas duct 3 there is a mechanism for mixing of combustible gases with air 8. Under the loading hopper for firewood 2 there is an accumulation hopper for charcoal 11. The mechanism of combustible gases mixing with air is arranged in the form of an injector made of a nozzle 9, along which combustible gases move, being the outer flow of the medium, and openings in the nozzle that serve as an input for air flow, being an inner flow of the medium.

EFFECT: higher efficiency of boiler operation due to rational burning of combustible gases produced during wood carbonisation.
