Abstract
The utility model discloses a blast furnace gas burner nozzle, which is characterized in that the outlet of a gas inlet pipe is provided with a gas distributing board connected with a corresponding casing pipe. An air isolating sleeve pipe with holes, and an air rotational flow device are arranged in the air inlet pipe, the air isolating sleeve pipe with holes is connected with the gas distributing board, and the air rotational flow device is arranged at an air outlet of an air inlet pipe. The outlet end of a burner nozzle is provided with a flame stabilizing cover of the outlet expanding straight pipe section. The utility model can singly use blast furnace gas, the combustion is stable, and the utility model does not need coke oven gas to use as a flame stabilizing source.
Description
The utility model relates to the burner that a kind of fuel is blast furnace gas, especially with a kind of blast furnace gas burner of stable flame cover.
Existing burner is when using blast furnace gas to make fuel, and the difficulty because blast furnace gas catches fire all adopts coke-stove gas to make steady burning things which may cause a fire disaster, and the passage of coke-stove gas is set in burner.Therefore, nozzle structure, coal gas system be more complicated all, and then can not adopt when not having coke-stove gas, also can't operate as normal.
The purpose of this utility model provides a kind of blast furnace gas burner, and it does not need to make steady burning things which may cause a fire disaster with coke-stove gas, can only use the burning of blast furnace gas homeostasis ground.
The purpose of this utility model is achieved in that in the gas inlet pipe outlet coal gas distribution plate is set that the coal gas distribution plate links to each other with distribution sleeve; Air insulated sleeve pipe and air cyclone with holes are set in air intake duct, and the air insulated sleeve pipe links to each other with the distribution plate of coal gas, and air cyclone is arranged on the air outlet slit place of air intake duct; The port of export at burner is provided with export expansion straight length stable flame cover.
Coal gas burner of the present utility model, coal gas will be dispersed into multiply by distribution sleeve and flow out, air is divided into secondary and supplies with, primary air flows between each plume of coal gas with low flow velocity by air insulated sleeve pipe with holes, strengthen mixing empty, coal gas, auxiliary air flows out through cyclone, utilize the rotation of air to flow out, reinforcement is empty, coal gas further mixes, swirling eddy forms and refluxes simultaneously, reach the purpose of steady flame, the export expansion straight length stable flame cover of the port of export setting of burner can reduce the flue gas amount of entrainmenting, and reaches smooth combustion.In order to observe fired state, the place is provided with peep-hole at gas inlet pipe.
Coal gas burner of the present utility model, simple in structure, can utilize the burning of blast furnace gas homeostasis ground, reduced the pipeline of coke-stove gas, coal gas system is simple, can save the pipe-line construction investment, safeguards also therefore simple.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is overall structure figure of the present utility model.
Fig. 2 is the overall structure figure of the utility model band peep-hole.
Among the figure, part 1 is a gas inlet pipe, and part 2 is air intake ducts, and part 3 is coal gas distribution plates, and part 4 is distribution sleeve, and part 5 is air insulated sleeve pipes with holes, and part 6 is air cyclones, and part 7 is export expansion straight length stable flame covers, and part 8 is peep-holes.Its annexation is: in gas inlet pipe 1 outlet coal gas distribution plate 3 is set, and links to each other with corresponding distribution sleeve 4; Air insulated sleeve pipe 5 with holes and air cyclone 6 are set in air intake duct 2, and air insulated sleeve pipe 5 with holes links to each other with coal gas distribution plate 3, and air cyclone 6 is arranged on the air outlet slit place of air intake duct 2; The port of export at burner is provided with export expansion straight length stable flame cover 7, and 1 place is provided with peep-hole 8 at gas inlet pipe.When coal gas burner of the present utility model is worked, coal gas will be dispersed into multiply by distribution sleeve 4 and flow out, air is divided into secondary and supplies with, primary air flows between each plume of coal gas with low flow velocity by air insulated sleeve pipe 5 with holes, mix more fully with coal gas, auxiliary air flows out through cyclone 6, utilize the rotation of air to flow out the further mixing of strengthening sky, coal gas, swirling eddy forms and refluxes simultaneously, reach the purpose of steady flame, the export expansion straight length stable flame cover 7 of the port of export setting of burner can reduce the flue gas amount of entrainmenting, and reaches smooth combustion.The peep-hole 8 that is provided with at gas inlet pipe 1 place can be observed fired state, and the flow of regulating coal gas or air can make burning reach optimum state.
