Description
Technical field
The invention belongs to coal dust and light equipment technical field, particularly to a kind of hydrogen and oxygen electrolyzing gas ignition coal burner.
Background technology
It is known that the igniting of existing thermal power plant large coal powder boiler and combustion-supporting, it is mostly device Large Oil rifle in the secondary air duct of coal burner, complete oil firing during ignition trigger.The evaporation capacity 670 each ignition oil of ton hour boiler of one 200,000 kilowatts of unit is more than 50 tons, and power plant of China is many lights a fire for power plant with light diesel fuel, and this is a kind of serious high-rank fuel waste.
Currently available make to replace fuel ignition burner and main burner have plasma non-oil ignition surely to fire, high temperature air non-oil ignition surely fires, three kinds of technical approach of hydrogen or oxygen gas ignition smooth combustion technology.
nullPlasma non-oil ignition smooth combustion apparatus is by ignition spout、Negative electrode、Anode、Water-cooling system、The part composition such as large power supply，Use the large power supply of about 120kW～400kW，Ignition temperature is up to the plasma arc of degree up to ten thousand，Realize coal dust heating、Reliable ignition and steady combustion，There is igniting fast、Reliable and stable、Coal adaptability more extensively waits various features，It is disadvantageous in that，High-power、Degree high temperature up to ten thousand cause negative electrode、Anode scaling loss is serious，Even if taking water-cooled measure，The most tens of hours of tungsten cathode life-span，The most hundreds of hours of anode life，Need to frequently change negative electrode and anode，Rather bother，Once fault，Affect the safe and reliable operation of station boiler，And consume the strategic materials materials such as more valuable tungsten，And power consumption is higher，As a example by the power station of corner tangential firing，Separate unit boiler configuration four set plasma burner，Power reaches 480kW～1600kW，Separate unit boiler annual operating cost is up to about 5,000,000.
High temperature air non-oil ignition smooth combustion apparatus, by port, high-frequency induction head, large power supplies etc. form, use the high-frequency induction system of tens of kilowatt, by the eddy current electrocaloric effect of metal pipe-wall, air is heated high temperature, realize lighting and surely firing of coal dust, there is host inorganic tool moving component, reliability is higher, various features, it is disadvantageous in that, the temperature of air heating, the restriction of metal of originally experiencing license wall temperature, and the thermal capacity of air own is relatively low, ature of coal is the poorest, water content is the highest, its thermal capacity is the biggest, coal dust possibly cannot be heated to burning-point and be lighted by high temperature air at any time, loss of ignition rate is higher, apply bigger by effect on coal quality, coal adaptability is poor.
Hydrogen or oxygen gas ignition smooth combustion apparatus, it is in charge of by the regulation and control hydrogen of specific proportioning, carrier of oxygen and mixes merga pass electricity ignition device at the burning column of flame after burner and ignite, the mode that this hydrogen, carrier of oxygen are in charge of into burner regulates and controls proportioning inconvenience, they generally use gas tank storage, frequently change, even if in order to reduce replacing during use, multiple gas tanks are connected, its pipeline connected once leaks, and detonation easily occurs, even explodes, be absolutely unsafe；The direct of travel of coal dust-air mixture is parallel with burning column of flame flame direction or has less angle, cannot the high temperature of fully utilized oxyhydrogen flame, burn insufficient through oxyhydrogen flame at coal dust-air mixture, bigger combustion zone cannot be formed, and then need the continual continuous work of oxyhydrogen flame, to reach the purpose surely fired, thus cause the raising of job costs.
Summary of the invention
For solving above-mentioned technical problem, the present invention proposes a kind of hydrogen and oxygen electrolyzing gas ignition coal burner, and it uses the hydrogen and oxygen gas mixture of electrolysis unit electrolysis water directly to enter stove Vertical Flame and lights, it is not necessary to regulation and control, safe and reliable, environmental protection and energy saving.
The technical scheme is that and be achieved in that:
A kind of hydrogen and oxygen electrolyzing gas ignition coal burner, it includes tubular shell, burner plate, electrolysis aquatic product hydrogen or oxygen gas pipe and holds together combustion pipe, a coal dust windband pipe it is set with in described tubular shell, in a coal dust windband pipe, it is set with combustion pipe, the burner plate of the band burning column of flame it is provided with in holding together to fire pipe, this burning column of flame is perpendicular to the direct of travel of coal dust-air mixture, and the burning column of flame is connected with electrolytic water oxyhydrogen generator by being electrolysed aquatic product hydrogen or oxygen gas pipe；It is communicated with secondary wind inleting tube on described tubular shell.
Preferably, it is additionally provided with a point windband pipe between described tubular shell and a coal dust windband pipe.
Preferably, the port of export of described point of windband pipe and a coal dust windband pipe is provided with rotary wind guide grid.
The hydrogen and oxygen electrolyzing gas ignition coal burner of the present invention has pipeline connection compared with tradition hydrogen or oxygen gas ignition smooth combustion apparatus and is simply not susceptible to reveal；Electrolysis wetting system aerogenesis output gas is exactly one oxygen of two hydrogen, and the proportioning of burning gases is just right；The gas combustion being ignited fiercely is difficult to be gone out by coal dust wind, temperature controls up to the size of the size available current of about 3000 degree flames, easy to operate control is easy, any of the above for fugitive constituent 24 coal dust can be lighted with 10-20 degree electricity, if fugitive constituent can suitably increase electric current output less than less than 24, increase flame.Lighting of various coal dust can be met, have simple to operate easy to control, the advantage of energy-conserving and environment-protective.
