Abstract
The utility model relates to a burner nozzle system used for a combustor of a magnesium-smelting reducing furnace, in particular to a premix burner nozzle with an air purging device. The premix burner nozzle system with the air purging device comprises two premix burner nozzles, wherein the air inlet ends of the two premix burner nozzles are respectively connected with a natural gas pipeline and an air pipeline through a natural gas fast-switching valve and an air fast-switching valve, and the smoke gas outlets of the premix burner nozzles are connected with the air pipeline and a smoke gas pipeline through a two-position three-way valve; and after the natural gas fast-switching valve is closed, the air fast-switching valve is opened to feed in air, so that the purging function can be realized, namely the air purging device is additionally arranged on the natural gas pipeline so as to purge residual fuel gas.
Description
Technical field
The utility model relates to a kind of burner system that the magnesium smelting reducing burner uses that is used for, and is specially a kind of premix burner that has air purge set.
Background technology
Current production of magnesium by pidgeonprocess uses single or combustion system of two brunched burner nozzles composition with the reduction furnace burner more, combustion gas and air mix, burn after entering in the stove respectively, occur incomplete mixing in mixed process easily, cause air too much or very few, it is insufficient to burn, waste of fuel.The patent No. is 200920102659.2 to disclose a kind of metal magnesium reduction furnace integrated energy-saving type heat-accumulating burner.The weak point of this burner is exactly the process that is not pre-mixed in burner.
Summary of the invention
The utility model mixes inhomogeneously in stove in order to solve in smelting the magnesium process combustion gas and air, burns inadequate problem and a kind of premix burner that has air purge set is provided.
The utility model is realized by following technical scheme, a kind of premixed burner, the output that the smoke outlet that comprises heat storage in the combustion gas injection pipe, combustion gas injection pipe of the import that has natural gas and air, combustion gas injection pipe is connected with two-position three-way valve, two-position three-way valve is communicated with air hose and fume pipe respectively, and the front end of heat storage is provided with pre-mixing cabin in the described combustion gas injection pipe.
A kind of premix burner that has air purge set, comprise two premixed burners, the inlet end of two premixed burners is cut valve soon by natural gas respectively and is cut valve soon with air and be connected natural gas line and air duct, the exhanst gas outlet of premixed burner connects air duct and flue by two-position three-way valve, after natural gas was cut valve soon and cut off, air was cut valve soon and is opened air is sent into, and realizes purging function, be the so-called air purge set that on gas pipeline, increases, to purge remaining combustion gas.
The utility model is to constitute a combustion system by 2 premixed burners, when the 1# burner supplies combustion gas, air burning heat supply, cuts the combustion gas that valve events cuts off the 2# burner soon by 2#, by 2# two-bit triplet valve events, realizes the smoke evacuation of 2# burner.When the 2# burner supplies combustion gas, air burning heat supply, cut the combustion gas that valve events cuts off the 1# burner soon by 1#, by 1# two-bit triplet valve events, realize the smoke evacuation of 1# burner.Do action is finished primary combustion.
After the commutation, cut soon in the pipeline behind the valve and can slowly overflow to body of heater by this part natural gas of residual a certain amount of natural gas, produce imperfect combustion, cause the combustion gas waste.By increasing the residual combustion gas of air fast cutting valve moment air purge (purge time is 1 second), after mixing, combustion gas and air enter completing combustion in the stove, can effectively utilize combustion gas.
Change combustion gas and air hybrid mode, after pre-mixing cabin is mixed, spray in the stove by mixing in the original stove to change into earlier again, make burning more abundant, avoided too much or very few, the inadequate situation of burning of air effectively, and the increase air purge set has utilized the energy to greatest extent on gas pipeline.
Compared with prior art, burner described in the utility model has realized that the preheating of combustion air and flue gas heat accumulate the alternately commutation of recovery, by the big up and down commutation of two burners, has realized the uniform and stable of furnace temperature and jar temperature, has prolonged the service life of reduction jar.By increasing blow device, avoided residual natural gas generation imperfect combustion in the Gas Pipe of commutation back, effectively utilized combustion gas.
