COMBUSTION METHOD OF CONTAMINATED INDUSTRIAL GASEOUS FUEL AND BURNER DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2015 - IPC F23D14/24 F27B21/08 

FIELD: heating.

SUBSTANCE: invention relates to combustion of contaminated industrial fuel and can be used in metallurgy, chemical industry and other branches to obtain high-speed and low-temperature flow of combustion products. Gaseous fuel is supplied to a combustion chamber with a perforated wall and mixed with air delivered through chamber walls cooled by it with further exit of combustion products through the outlet nozzle of the combustion chamber. With that, gaseous fuel is supplied to the combustion chamber through a vortex cyclone chamber as a continuous flow spirally along the surface of the perforated wall of the combustion chamber, the length of which is 1.2 to 2.0 of its diameter. Possible deposits on the inner side of the combustion chamber during operation are burnt out little by little with carry-over of residues from the combustion chamber or easily removed during preventative maintenance of the burner.

EFFECT: invention allows intensive combustion of contaminated industrial gaseous fuels.
