Description
Technical field
The present invention relates to a kind of boiler plant that is used for heating and hot water engineering, be specifically related to a kind of gas boiler.
Background technology
After coal burnt in producer, the air of furnace bottom is limited, make the coal can not completing combustion, thereby produce a large amount of carbon monoxide, at this moment the fuel gas of discharging through imperfect combustion of the coal in the producer just be called producer gas.The production process of producer gas is at first making air pass through fuel bed, and carbon and oxygen react to improve temperature; Steam and air are mixed by fuel bed, and carbon and steam and oxygen generation hybrid reaction are to generate producer gas.The boiler that utilizes producer gas to act as a fuel at present is provided with a coal furnace mostly and is used for producing coal gas, again the coal gas that produces being conducting to another by pipeline is used in the gas burner of combustion gas row again and lights, thereby make coal obtain completing combustion, the tail gas of Pai Chuing does not contain poisonous atmospheric CO substantially yet simultaneously, is beneficial to environmental protection.The disclosed a kind of producer gas boiler of Chinese patent literature CN2453232Y for example, this technical scheme is set up in parallel gas generating chamber and gas burner, and is provided with water jacket in the outside, furnace wall.Being of its shortcoming, after being delivered in the gas burner via pipeline, coal gas also needs to light, lighting during the content of fuel gas in uncertain gas burner can breaking out of fire and explosion accident, abnormally dangerous, the greatest problem that this also this just boiler runs in actual applications.
In order to attempt to address the above problem, american documentation literature US2005/0284421A1 discloses a kind of coal-burning boiler, and first combustion chamber of bottom and second combustion chamber on top are opened, are divided into to this technical scheme with the combustion chamber with fire rated partition lattice with holes.Above-mentioned first combustion chamber is used for fire coal, and produces coal gas therein; Above-mentioned second combustion chamber on the top coal gas that above-mentioned first combustion chamber produces that then is used for burning.Above-mentioned first combustion chamber is equivalent to gas generating chamber, and above-mentioned second combustion chamber is equivalent to the gas burner.The design principle of this technical scheme is that the high temperature action that the coal gas that will produce in the coal cinder partial combustion process produces during the coal cinder burning in first combustion chamber is issued to burning-point, cooperates the air oxygen supply to burn.But there is following shortcoming in actual applications in the boiler of this technical scheme: the generation principle by producer gas is determined, in boiler, fill out the coal that needs at first to light bottom behind the coal, in the incipient stage, the coal seam, upper strata is burning not, reach burning-point thereby the temperature in second combustion chamber can't be instant, promptly can't light the coal gas that produces in first combustion chamber automatically this moment.Temperature in above-mentioned second combustion chamber did not reach in the time period of burning-point, and the coal gas in above-mentioned second combustion chamber has just been discharged boiler under the situation of not burning, atmosphere has been caused pollution.If boiler is bigger, the coal amount of dosing is more, and it is more obvious that this shortcoming also just embodies.This technical scheme does not solve that coal gas need carry out reignition in the gas boiler, the technical problem of breaking out of fire easily, blast.
