DIRECT ACTION HEAT GENERATOR FOR GRAINWORKING Russian patent published in 2017 - IPC F26B23/02 

FIELD: machine engineering.

SUBSTANCE: heat generator includes an air intake hole, an air duct, a combustion chamber, a high-pressure fuel pump, an injector, a nozzle for the exhaust of combustion gases from the combustion chamber. The combustion chamber in cross-section has at least one reflector in the zone of maximum expansion of gas mixture ignition, made in the form of a shell of hollow truncated cone, and connected to the inner wall of the combustion chamber, one end of the shell is free and placed at an angle to the combustion chamber wall in direction of gas mixture combustion. The combustion chamber at the inlet has a distributing unit in the form of a mixing nozzle with inlet channels, the holes of which are connected to the delivery device in the form of an impeller, whose cold compressed air is supplied to a distribution unit, and gas having a spark plug. The combustion chamber is provided with a shield in the form of a plate mounted in space coaxially with the output diminishing opening of truncated cone, whose diameter is equal to or larger than the diameter of the outlet of truncated cone. The device for regulating the zone of heated air is made with a stream-guiding system in the form of horizontal blinds with the possibility of controlling them by means of a pull rod with a rotary handle made outside the nozzle with a horizontal rack in the form of toothed projections.

EFFECT: automatic operation mode, increased reliability, stability in operation and fire safety.
