BURNER FOR COMBUSTION OF GAS AND BLACK OIL Russian patent published in 2010 - IPC F23D17/00 

FIELD: power engineering.

SUBSTANCE: method is realised in burner for combustion of gas and black oil having three coaxial circular channels: outer channel for supply of secondary air, central channel for supply of primary air, middle channel, in which gas supply pipes are installed with various diametres, and nozzle for combustion of black oil in central channel, besides at the inlet of each coaxial channel of burner there are tangential registers for air swirling, at the same time as for the first flow of primary air - into central channel, the second flow of primary air - into the middle channel, gas supply pipes are arranged with bent outlet ends, rotating around axis and with possibility of axial displacement, and nozzle for combustion of black oil is arranged with the possibility of axial displacement, besides tangential registers, gas supply pipes and nozzle are connected to electric motors with servodrives controlled according to computer program.

EFFECT: intensification of fuel combustion to reduce chemical underburning in the whole range of thermal load changing in boiler set.
