Abstract
The utility model provides a three air supply safety combustors, including the combustion chamber, with communicating air conduit in combustion chamber and fuel channel, fuel channel includes natural gas line, coke oven gas pipeline, blast furnace gas pipeline, air conduit includes air conduit I and air conduit II, from center outwards arrange in proper order natural gas line, coke oven gas pipeline, air conduit I, blast furnace gas pipeline, air conduit II. The utility model is suitable for a multi -gas fuel to have do not draw a temper, flame -out, high -efficient ann congruent advantage.
Description
Technical field
The utility model relates to a kind of burner, may be used for, in smelting iron and steel enterprise or gas fired-boiler, being applicable to the burner of multiple gases fuel.
Background technology
In smelting iron and steel enterprise sintering or gas fired-boiler, great majority adopt single source of the gas burner at present, in some small-sized iron and steel enterprises, do not have gas holder to carry out stored-gas fuel.The blast furnace gas that blast furnace produces or the coke-stove gas that coke oven produces, be piped directly in boiler and use, if blast furnace is once occur abnormal, gaseous-pressure will be caused to fluctuate abnormal, fuel air feed even can be caused to interrupt.After of short duration dying, burner fuel valve does not also close to be closed, and recovers again air feed and is just easy to cause fuel gas to enter high-temperature burner hearth, form flammable gas explosion condition, cause the bursting of boilers.
Summary of the invention
The purpose of this utility model is to provide a kind of burner being applicable to multiple gases fuel, and this burner has the advantages such as not tempering, flame-out, highly effective and safe.
The utility model realizes like this.A kind of three source of the gas safety burners, comprise combustion chamber, the air duct communicated with combustion chamber and fuel channel, described fuel channel comprises natural gas line, coke oven gas pipe, blast furnace gas pipeline, described air duct comprises air duct I and air duct II, outwards arrange successively from center natural gas line, coke oven gas pipe, air duct I, blast furnace gas pipeline, air duct II.
Preferably, natural gas line, coke oven gas pipe, air duct I, blast furnace gas pipeline, air duct II are in concentric drums sleeve structure.
Further, the exit of air duct II arranges air hybrid blade II, and the exit of air duct I arranges air hybrid blade I, and air duct II is connected air interface with air duct I.
Further, natural gas line connects natural gas interface.
Further, coke oven gas pipe connects coke-stove gas interface, and the exit of coke oven gas pipe arranges coke-stove gas hybrid blade.
Further, blast furnace gas pipeline connects blast furnace gas interface, and the exit of blast furnace gas pipeline arranges blast furnace gas hybrid blade.
Three source of the gas safety burners of the present utility model, may be used for:
1, blast furnace gas-coke-stove gas-natural gas, combination;
2, blast furnace gas-coal gas of converter-liquefied petroleum gas, combination;
3, coal gas of converter-coke-stove gas-natural gas, combination;
4, hydrogen production exhaust gas-coal gas of converter-natural gas, combination etc.
Three source of the gas safety burners adopt non-premix to try structure, and namely fuel gas and air are isolations before combustion chamber, do not have fuel gas in air duct, do not have combustion air in fuel gas.In combustion chamber, fuel gas mixes with air while burn, and flame will not burn in fuel channel, and therefore this burner has not tempering feature.
Three source of the gas safety burners use three kinds of gases on fuel, this three kinds of sources of the gas that are in operation all can not be died at synchronization, even if two kinds of gases are of short duration dies for certain, a kind of gas is also had to keep burning, this guarantees kindling material not extinguish in burning, source of the gas of dying just can light gas rapidly against kindling material after recovering air feed, there will not be a large amount of fuel gas to enter high-temperature burner hearth, form furnace explosion condition.Therefore this burner has very high security.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
In figure: 1. combustion chamber 2. air hybrid blade II 3. blast furnace gas hybrid blade 4. air hybrid blade I 5. coke-stove gas hybrid blade 6. coke-stove gas interface 7. natural gas interface 8. blast furnace gas interface 9. air interface 10. natural gas line 11. coke oven gas pipe 12. air duct I 13. blast furnace gas pipeline 14. air duct II.
Detailed description of the invention
For the ease of understanding, describe the utility model in detail below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of three source of the gas safety burners, comprise combustion chamber 1, the air duct communicated with combustion chamber 1 and fuel channel, described fuel channel comprises natural gas line 10, coke oven gas pipe 11, blast furnace gas pipeline 13, described air duct comprises air duct I 12 and air duct II 14, outwards arrange successively from center natural gas line 10, coke oven gas pipe 11, air duct I 12, blast furnace gas pipeline 13, air duct II 14.Natural gas line 10, coke oven gas pipe 11, air duct I 12, blast furnace gas pipeline 13, air duct II 14 are in concentric drums sleeve structure.
The exit of described air duct II 14 arranges air hybrid blade II 2, and the exit of air duct I 12 arranges air hybrid blade I 4, and air duct II 14 is connected air interface 9 with air duct I 12.
Described natural gas line 10 connects natural gas interface 7.
Described coke oven gas pipe 11 connects coke-stove gas interface 6, and the exit of coke oven gas pipe 11 arranges coke-stove gas hybrid blade 5.
Described blast furnace gas pipeline 13 connects blast furnace gas interface 8, and the exit of blast furnace gas pipeline 13 arranges blast furnace gas hybrid blade 3.
Due to natural gas and these two kinds of gas heating values of coke-stove gas higher, specific volume is less, natural gas and coke-stove gas are arranged in the center of burner, air-breathing is arranged at the skin of these two kinds of fuel, producer gas is set high at the outer cloth of air layer, arrange a layer of air again at the skin of blast furnace gas, form multilayer " Fuel-air-Fuel-air " arrangement form.Blast furnace gas, coke-stove gas, air outlet slit place, the jet-stream wind forming different rotation rates under the effect of guide vane (angle of guide vane is different) fully mixes.Accomplished the optimum Match of fuel and air by the control valve of each gaseous fuel and the regulating and control of air control valve, realize burning completely.
