Description
Technical field
A kind of gas combustion apparatus is related to a kind of fuel gas buring, particularly metallurgical process blast furnace gas or mineral hot furnace coal gas
Fuel gas with low heat value burner.
Background technology
In metallurgical process production process, it is to have that can generate the largely flammable flue gas containing CO, the recovery processing of flue gas
Effect is reduced pollution, is improved the important means of productivity effect using the energy.
It is low-heat value gas in the blast furnace gas or mineral hot furnace coal gas of metallurgical production process generation, is filled using existing burning
It puts, it may occur that the problems such as ignition difficulties and poor stability, flame-out phenomenon can frequently occur in use of burning, affect in fact
Border application effect.
Invention content
For the purpose of this utility model aiming at above-mentioned prior art Shortcomings, providing a kind of can effectively overcome igniting tired
The difficult and frequent flame-out problem of generation, combustion stablized gas combustion apparatus.
The purpose of this utility model is achieved through the following technical solutions.
A kind of gas combustion apparatus, it is characterised in that its structure includes：
Burning cavity, the cavity are tubular housing；Air is provided on cavity wall and is passed through mouth；The side of cavity is coal gas

Igniter, the firing tip of the igniter are located at the resistance plate washer in gas piping.
A kind of gas combustion apparatus of the utility model, it is characterised in that the thermal current outlet conduit is negative-pressure pipeline.
A kind of gas combustion apparatus of the utility model, it is characterised in that the igniter is high-frequency pulse igniter.
A kind of gas combustion apparatus of the utility model can have solution to utilize the low heat values such as blast furnace gas or mineral hot furnace coal gas
During coal gas, occur it is frequently flame-out, the problems such as ignition difficulties and poor combustion stability, offer hot-fluid gas that can be continual and steady
As heating source, reliable guarantee is provided for the comprehensive utilization low-heat value gas such as blast furnace gas or mineral hot furnace coal gas for body.
Description of the drawings
Fig. 1 is this structure diagram with a kind of novel gas combustion apparatus.
Specific embodiment
A kind of gas combustion apparatus, structure include：Burning cavity 1, the cavity are tubular housing；It is opened on cavity wall
There is air to be passed through mouth；The side of cavity is gas inlet, and the other end is hot gas outflux after burning；Gas piping 2, the gas pipe
Road is connected in by connection flange in the gas inlet of burning cavity side, and the gas piping end at connection flange is equipped with band
There is the resistance plate washer 3 of several through-holes；Thermal current outlet conduit 4, the pipeline are connected in burning cavity opposite side by connection flange
Burning after on hot gas outflux；Air pipeline 5, which, which is connected in by connection flange on cavity wall, is provided with air
It is passed through on mouth；Igniter 6, the firing tip of the igniter are located at the resistance plate washer in gas piping.
A kind of gas combustion apparatus of the utility model, the thermal current outlet conduit are negative-pressure pipeline；The igniter
For high-frequency pulse igniter.
During practical operation, thermal current outlet conduit is drawn air and coal gas in air pipeline by the negative pressure wind that wind turbine generates
Coal gas displacement in pipeline, the wind turbine frequency of thermal current outlet conduit connection are adjusted to low-frequency operation, open igniter, lead to
Enter coal gas, coal gas is moved with negative pressure wind direction combustion chamber, collected at baffle by perforated baffle, and coal gas solubility increases, due to negative
Wind effect is pressed to reduce, improves ignition effectiveness.
Coal gas can be closed if loss of ignition and enters pipeline, is siphoned away the coal gas of pilot chamber by negative pressure wind, then carries out weight
New sparking operation, improves safety coefficient.
If lighting a fire successfully, fan delivery can be adjusted, raising coal gas inlet can be suitable by adjusting wind turbine frequency
Thermal current flow and heat, utilized as heat source.
