  customer praised  two stage coal gasifier

Coal gasifiers using coal or coke,carbon material as fuel, air and water vapor are mixing for gasification agent in a gasification process.Using the automatic coal feeding, automatic slagging, the unique pagoda type heat-resisting cast steel grate,which has powerful broken slag, slag loosening, breathable function. No smoke in the burning process,concentration of sulfur dioxide and soot emissions are in line with environmental standard GB9078-1996.Many coal gasifier advantages,such as,Reasonable gas gasification,simple design,lower investment,safe and convenient operation,simple operation and maintenance,which are well received by customers praise,this is my company launched a new area of intelligent and efficient energy-saving environmental protection products.

 

 

product features
1.The gasifier equipe the bucket to left coal, double bell jar feeding mechanism, and better the sealing effect, its adjustable pocket flap and conical coal unit can be used combinable, coal distribution uniformity,
2.Basically same thickness in cross-section fuel, so as to improve coal gasification efficiency, put an end to occur the flaming phenomenon of partial furnace.
3.The furnace adopts full water jacket, self-produced steam, not outside for steam, pressure stability, favorable gasification in hearth, good cooling effect in furnace, water jacket inner sleeve deformation.
3.Double bell coal feeder bring better sealing;
4.Wet rotary ash disk system adopt a tower type pyramid pentagonal grate,material is made by the steels casting.Design of small ash knife push slag, which add the mechanism of slag,broken slag structure,which enable uniform distribution and operation of gasifying agent.the material layer in the distribution is relatively stable, in the best gas state, and reduce the carbon content of slag, to solve the traditional gasification furnace in order to prevent coking frequent tie brazing, throw the problem of fire;this structure can make the agency distribution uniformity,current operation uniform slag,furnace is relatively stable the best state of gas,reduce the carbon content of slag, and have solved the traditional gasifier in order to prevent coking frequent fire drill and flaming out.
5.With isolation of water seal dust catcher, during the outage boiler stop, which can improve water closed height, cut off the gas generator and thermoelectrical furnace between gas and make sure have no pressure, put an end to happen the tempering explosion.
6.With refractory concrete roof insulation,cooling water saving.
7.Use the special burner, this gas furnace are based on different specifications, different using conditions, equipped with a special "ejector type" burner, which can bring some usages, such as sufficient fuel combustion, stable operation, long life and other characteristics;

 

 The principle of the coal-gas gasification

 Continuous gas gasifier adopt coal with 20-80 mm size as ideal fuel, when the coal was fed into furnace by adding coal scuttle, after met the gasification agent (air and water vapor) by bottom drum charging into, which make coal and water vapor reacted, formed the flammable gas such as carbon monoxide and hydrogen, thus which reach a state of complete gasification, steadily make gas continuously. The material layers are formed a five stages from bottom to top: ash layer,oxide layer, reduction layer, retorting layer, dry layer.
Blasted the gasification agent, passing the slag layer firstly, and preheating on this layer, when the gas are rise into the high temperature fuel layer, carbon and oxygen generating the following reaction: 2 C + O = 2 co + Q 2 co + O2 = 2 C02 + Q C + O = C02 + Q
Several reaction is exothermic reaction, temperature is very high, this layer called oxide layer.
The heat generated in the oxide layer continue to rise,with the upper fuel contacting, resulting in a reduction reaction, main restore layer reaction:
C02 + C = 2 CO - Q C + H2O = C02 + 2 H2 - O C + H2O = CO + H2 - Q
Times reduced layer is mainly used to generate carbon monoxide and excess water vapor. CO + H2O = C02 + H2 + Q
Besides,the generation of methane side reaction: C+2H2=C04+Q
The hot gas have rosed in the reduction zone,heating the upper coal steam,form the dry distillation and drying layer.
Dry distillation of volatile organic can be evaporated under the physical thermal effect of the rising heating gas,meanwhile, the water in the dried layer can be dried completely through this same heating.
