Description
Technical field
The present invention relates to a kind of combustion apparatus, be specially a kind of bituminous coal smokeless combustion machine.
Background technology
Traditional combustion equipment mostly adopts fixed grate, is a kind of mode of unidirectional burning, and fire coal burns above fire grate, coal also carries out above fire grate, and this has just caused coal moment, and burning, supply falls short of demand for required air, bituminous coal anoxycausis produces a large amount of carbon monoxide, enters in atmosphere.
Traditional hand-fired boiler and combustor, in combustion process, the coal initial stage, under the effect of high temperature, moisture in bituminous coal and the effusion of fugitive constituent, need a large amount of heats, also needs a large amount of oxygen to guarantee coal-fired abundant burning, and the reverse be true in burner hearth now, coal seam is partially thick, and the resistance that air enters strengthens, and causes oxygen supply deficiency in burner hearth, produce a large amount of carbon monoxide and the fugitive constituent of incomplete combustion, flow in atmosphere and cause over-emitting black exhaust phenomenon; Along with the continuous burning of bituminous coal,, in attenuation gradually, constantly reduce in resistance in coal seam, and the input quantity of air is constantly increasing, and the discharge of surplus air, will take away a part of heat, causes fire box temperature to decline.
All hand-fired boilers and combustor, be mostly equipment leg space ventilation in the market, top coal, burning is also carried out on top, in the moment of coal, the air that fired coal combustion is required, with equipment the air of confession do not mate, make fired coal combustion incomplete, produce a large amount of black smokes, dust from flying, the carbon monoxide of incomplete combustion etc. have the imflammable gas of harm to human body and environment, directly from chimney, enter atmosphere, cause environmental pollution.
Summary of the invention
The present invention is incomplete in order to solve combustor fired coal combustion, produce a large amount of black smokes, dust from flying, the carbon monoxide of incomplete combustion etc. have the imflammable gas of harm to human body and environment, directly from chimney, enter atmosphere, cause the problem of environmental pollution, a kind of bituminous coal smokeless combustion machine is provided especially.
The present invention takes following technical scheme: a kind of bituminous coal smokeless combustion machine, comprise spiral propeller, air blast and fire pot, described spiral propeller upside is provided with coal bunker, spiral propeller is connected with fire pot, fire pot one side-lower is provided with the air blast communicating with it, fire pot upside is provided with blast cap, and the fire pot base plate of fire pot bottom is provided with the plate that stirs by driving mechanisms control.
Described driving mechanism comprises bevel gear driver, balancing point reductor and motor, stirs plate and is connected with bevel gear driver by feather key, and bevel gear driver is connected with balancing point reductor, and balancing point reductor is connected with motor.
Described fire pot week side is provided with air compartment outside plate, and solar or lunar halo is stamped on fire pot top.
Described blast cap upside and all sides of fire pot are equipped with the aperture that diameter is 15mm.
1. coal-feeding mode:
Fire coal is divided into following step in combustion process: fire coal enters after the burner hearth of high temperature, first moisture in fire coal be evaporated, for the larger coal dust of water content, in 15 seconds, just can remove major part, be attached to the inherent moisture in coal dust, need the time of growing to overflow, the effusion of moisture is the process of heat absorption, can cause the reduction of fire box temperature.The utility model, by technological innovation, adopts enclosed coal feeder, has stopped the possibility that cold air enters combustor, has also reduced the heat loss that smoke evacuation brings.With spiral propeller, coal is sent in fire pot slowly, prevented that the coal ash in coal process from splashing, reduced the drift of dust.The fire coal newly adding mixes with spent coal from bottom to top, has had higher temperature, has guaranteed the continuation of burning; The utility model is by stirring the continuous stirring of plate, the fire coal newly adding fully mixes with the fire coal having heated, the fire coal of high temperature decomposites flammable fugitive constituent and carbon monoxide, coal-fired district through high temperature, after coal-fired preheating, dry and distillation, above fire coal, the air required with burning mixes, and produces omnibearing burning.
2. air supply mode:
Coal-fired burning velocity, relevant with coal-fired character, want overheavy firing process, need to improve as much as possible the temperature of burning, reduce as much as possible coal-fired granularity.The utility model is by the effect of air blast, wind is directly sent into fire pot bottom, the coal-fired layer of air through having burnt, under the effect of stirring plate, in the moving process making progress, having improved gradually the temperature of air, increased the quantity delivered of air, is the favourable condition of the combustion-supporting creativity of fire coal, fire coal has obtained abundant burning in steps in fire pot, has fundamentally changed the drawback of traditional combustion machine.
Improvement due to two above-mentioned aspects, make the present invention there is peculiar structure, the combustion system of innovation, coal-fired in whole combustion process, burning uniformly from bottom to top, coal-fired after the coal-fired layer of high temperature, the carbon monoxide that the fugitive constituent of pyrolytic and incomplete combustion produce, there is higher temperature, on coal-fired top, produce lasting burning, make the temperature of kiln and industrial forge furnace, there is the raising of very large degree, and the process of coal-fired continuation burning, guaranteed the stability of kiln and forging temperature, met the requirement of every technique, improved the coal-fired thermal efficiency, put into the melting pot traditional combustion machine incomplete combustion, the phenomenon of over-emitting black exhaust, solved the social concern of energy waste.
Compared with prior art, the present invention passes through spiral propeller by fuel, send into continuously combustor,, make coal add gradually thermal decomposition from top to bottom, the sustained combustion under the condition of high temperature of its imflammable gas, in coal supply, the bottom of combustor, constantly sends into the required air of fuel combustion by air blast, has guaranteed the abundant burning of bituminous coal.Lasting coal-feeding mode due to this combustor, by fire pot bottom, stir plate by coal from bottom to top again, be pushed into the top of fire pot, the fuel that top is hot, under constantly heating, decompose the imflammable gas that produces a large amount of high temperature, and stir the air of fully supplying with under the continuous stirring of plate, ensured the required condition of burning.Continuous coal-supply way, has overcome the fixed grate of traditional combustion machine, and in combustion process, periodically coal supply, has caused in fired coal combustion process, and because the required air that burns does not mate, incomplete combustion, produces the phenomenon of over-emitting black exhaust.Meanwhile, the air-supply of this combustor is from bottom to top, and air is in the progressively heating of coal-fired layer, for coal-fired completing combustion provides good condition.The present invention has changed traditional coal-feeding mode, makes imflammable gas pass through red-hot fire coal, produces burning after reaching the required temperature of burning.In combustion process, temperature can reach more than 1200 ℃, and flame reaches 4-5 rice, and can sustained combustion, changed greatly the periodicity of traditional combustion machine burning and the disadvantage of incomplete combustion over-emitting black exhaust, has fully met the requirement of production, life.
