Description
Technical field
The present invention relates to a kind of cooking stove, be used for various boilers, kiln and hotblast stove.
Background technology
In recent years, people are in order to reduce coal furnace for atmospheric pollution, developed the new technology of coal-fired gasification furnace, the working mechanism of coal-fired gasification furnace and the producer gas generator of industrial use are basic identical, please refer to Fig. 1, in producer gas generator, coal be from top to bottom add, vaporized chemical then is from bottom to top to carry out countercurrent movement, and chemical reaction and thermal exchange take place between them.Thereby in producer gas generator, formed several zones, be called " layer ".Carry out order according to gasification in the producer gas generator, producer inside can be divided into six layers: promptly ash bed 21; Zone of oxidation 22 (claiming fire bed again); Reducing zone 23; Destructive distillation layer 24; Drying layer 25; Dead level 26; Wherein zone of oxidation and reducing zone are referred to as responding layer again, and destructive distillation layer and drying layer are referred to as the coal charge preparation layer again.The effect of each layer is as follows:
Ash bed: produce lime-ash behind the coal combustion, form ash bed, it covers on the fire grate at the foot of producer.It mainly act as: a protects fire grate, and the high temperature of their not oxidized layers is burnt out; B preheating vaporized chemical after vaporized chemical (once air-supply) enters from furnace bottom, at first carries out heat exchange through ash bed, and the ash bed temperature is reduced, and gasification agent temperature raises.General vaporized chemical can reach about 300-450 ℃ in preheating; The c ash bed has also played the effect of cloth wind, makes the vaporized chemical that enters uniform distribution as far as possible in burner hearth.
Zone of oxidation: be also referred to as zone of combustion (fire bed).Violent burning takes place and generates carbonic acid gas in oxygen and the carbon in the fuel gone up from ash bed in the next vaporized chemical, and emits a large amount of heats.It is one of main region in the gasification, and the temperature of zone of oxidation generally is less than the ash fusion point of coal, is controlled at about 1200 ℃.
Reducing zone: be reducing zone above the zone of oxidation.Fervid carbon has very strong captures oxygen in the oxide compound and bonded ability with it, so in reducing zone, carbonic acid gas is become carbon monoxide and hydrogen with water vapor by carbon reduction.Therefore this one deck is also gained the name, and is called reducing zone, because reducing zone is positioned on the zone of oxidation, obtains a large amount of heats from the gas that rises, so reducing zone has the about 800-1100 of higher temperature ℃, and this just provides condition for the reduction reaction of needs absorption heat.And say that strictly reducing zone also has first, second branch, and the higher place of temperature of lower claims first reducing zone, and temperature reaches 950-1100 ℃, and the second layer is between 700-950 ℃.
The destructive distillation layer: the destructive distillation layer is positioned at the top of reducing zone, the gas that is risen by reducing zone is along with heat is consumed, its temperature descends gradually, thus destructive distillation layer temperature between 150-700 ℃, coal is under this temperature, go through the process of low-temperature pyrolysis, fugitive constituent generation cracking in the coal produces materials such as methane, alkene and tar, and being heated becomes gaseous state, promptly generate coal gas and overflow, become the integral part of coal gas by top drying layer.
Drying layer: drying layer is positioned at above the destructive distillation layer, that is to say the surface layer of fuel, and the heating gas of rising meets at this layer with the fuel of just going into stove, carries out heat exchange, and the moisture in the fuel is subjected to thermal evaporation.It is generally acknowledged that drying temperature is between room temperature-150 ℃.
Dead level: layer is fuel bed top, the intravital free zone of stove, and it mainly acts on is to compile coal gas.The gasification of carrying out in the producer gas generator is a more complicated, and existing gasification reaction also has destructive distillation and drying process.And in the producer of actual production, layering neither be very strict, adjacent two layers is interlaced often, and the temperature of each layer also is progressively transition.
Existing coal-fired gasification furnace has been used for reference the principle of coal-gas producer, its vaporizer and coal-gas producer are basic identical, vaporizer is the vertical direction setting, each bed of material spatially is a level, each bed of material thickness in a lateral direction is identical, vaporized chemical is along the axial direction due vertical uplift of vaporizer, cloth wind is even, combustionvelocity is even, each bed of material from top to bottom descends in combustion processes successively, for small-sized coal-fired gasification furnace, this gasification mode can produce a problem, because small-sized coal-fired gasification furnace is the hand firing, the coal cycle is a reducing zone, the destructive distillation layer, drying layer exhausts the back and only have ash bed in stove, again coal after the zone of oxidation, like this, newly go into stove fuel and need form reducing zone again, the destructive distillation layer, drying layer, inflammable gas content is low in the flue gas of Chan Shenging during this period, be difficult for lighting, form the dense smoke discharging that contains a large amount of carbon thus.Forming in first igniting has the long time again in the zone of oxidation process, because inflammable gas content is low, be difficult for lighting, and also can produce a large amount of dense smoke dischargings.Generally, the gap coal needs 4-5 hour ability after-flame, and gasification only accounts for the time about 1/3rd, and gas producing efficiency is extremely low, and fuel consumption is big, and gasification reaction is insufficient, and smoke discharge amount is big, contaminate environment.
