Summary of the invention
The purpose of this utility model is, the blast furnace gas producing for steel plant, coke-stove gas, coal gas of converter etc., design a kind of high low heat value dual fuel combined burning arrangement, make natural gas, blast furnace gas, coke-stove gas, several combustion gas of coal gas of converter can realize dual-fuel multifuel combustion, can make unsettled source of the gas be fully utilized, reach good combustion efficiency.
The technical solution of the utility model is: high low heat value dual fuel combined burning arrangement by quirk brick (1), single flow air register (2), be axially moveable blade air register (3), air duct 1(4), fuel gas with low heat value passage (5), high heating value blast tube (6), air duct 2(7), butterfly valve 1(8), burning torch mounting pipe (9), butterfly valve 2(10), ignition air gun (11), burning torch (12), fire inspection (13) form.High heating value blast tube (6) and fuel gas with low heat value passage (5) are carried respectively high heating value combustion gas and fuel gas with low heat value, high heating value blast tube is connected with two kinds of gas pipelines by different interfaces with fuel gas with low heat value passage, by different nozzles, spray into combustion chamber tissue burning, air duct 1(4) air in rotates to form swirling eddy through axial movable vane air register (3), with the abundant mixed combustion of fuel gas with low heat value, high heating value combustion gas and air duct 2(7) in air in exit, mix, through single flow air register (2) secondary rotating, mix, air duct 1(4), air duct 2(7) at air intake place, be respectively equipped with butterfly valve separately, aperture by butterfly valve regulates every kind of fuel gas buring required air quantity, reach the object of smooth combustion.
The utility model has the advantage of: exotic fuels, low calorie fuels be multifuel combustion simultaneously, a kind of combustion gas of also can burning separately; The independent air distribution of exotic fuels and low calorie fuels, air intake butterfly valve is respectively joined in two kinds of combustion gas, better adapts to the situation that two kinds of fuel-air requirements differ greatly; This burner is joined two kinds of air registers, and two kinds of fuel gas burings are adjusted separately wind, and exotic fuels source of the gas is relatively stable, selects single flow air register can reduce whole burner volume, simplified structure; Fuel gas with low heat value burning air register is selected and is axially moveable impeller air register, can make low calorie fuels and air good mixing by rotating handwheel adjusting vane angle, and combustion efficiency is better; This burner adapts to the coupling of pluralities of fuel, as natural gas and blast furnace gas multifuel combustion, natural gas and coke-stove gas multifuel combustion, natural gas and coal gas of converter multifuel combustion, coke-stove gas and blast furnace gas multifuel combustion, coke-stove gas and coal gas of converter multifuel combustion etc., wherein, what have significant practical applications most is blast furnace gas and coke-stove gas multifuel combustion.
