A DUAL FUEL BURNER FOR PRODUCING A RELATIVELY SHORT TURBULENT FLAME OF INTENSE HEAT

摘要

(A) a gas burner having a gas pipe containing a cylindrical part into which fuel gases are fed through a gas inlet pipe and a tapered part acting as a gas nozzle through which fuel gases are injected into a mixing chamber, and an air chamber with an air nozzle and an air Inlet pipe for supplying air circulating round the gas nozzle and discharging through the air nozzle into the mixing chamber and a refractory quirl fitted on the outlet end of the air nozzle; and (B) a liquid fuel gun having an innermost pipe, acting as an emulsion tube, and being disposed concentrically inside a dummy pipe which in turn being disposed concentrically inside a gas pipdjprovided with an atomising nozzle for producing an emulsion of liquid fuels and air/steam therein, the liquid fuel gun being connected at input end and at an emulsion nozzle at the output and for discharging the emulsion of liquid fuels and air/ steam into the mixing chamber, connected at outlet end of the innermost pipe.
