COMBUSTION CHAMBER Russian patent published in 2013 - IPC F23R3/32 F23C3/00 

FIELD: power industry.

SUBSTANCE: combustion chamber includes the first and the second pipes, an ignition device and a flame kernel formation unit. Combustible gas that is discharge through holes in the limits of the flame quenching distance flows through the inner space of the first pipe. Combustible gas that is discharged from holes of the first pipe is supplied to the second pipe. A combustion zone, where combustible gas supplied on the inlet side and from where the exhaust gas is distributed in the direction of the outlet side, is burnt inside the second pipe. Ignition device ignites combustible gas supplied to the second pipe using the flame kernel formed by means of the flame kernel formation unit. The first pipe is the inner pipe that includes combustible gas supplied from one end while the other end is a locked end. The second pipe is the outer pipe that is located around periphery of the first pipe with location of the combustion zone between them, and discharges combustible gas from one end while the other end is a locked end and located on the side of the other end of the first pipe. Flame kernel formation unit is located on the inlet side of combustion zone inside the second pipe, between the locked end of the first pipe and the locked end of the second pipe.

EFFECT: improving combustibility of combustible gas and increasing the service life of the flame kernel formation unit of the ignition device.
