METHOD AND DEVICE FOR BURNING BLASTING GASES Russian patent published in 2008 - IPC F23D14/20 

FIELD: combustion.

SUBSTANCE: method comprises branching the gas flow to be burnt out into at least two flows, directing the first flow branch of the gas to the shaped central member of the burner through the ring space and the second branch flow through the shaped outlet cross-section of the pipe, and mixing the flows in the combustion zone. The ring space is made of shaped ring critical section and is positioned in the outlet part of the shaped central member. The first flow is supplied through the shaped ring critical section and is speeded up to provide the sound velocity at the exit, and the second flow is directed at an angle to the first flow through the shaped outlet section of the pipe.

EFFECT: enhanced efficiency of combustion.
