Operation principle is as follows：
Refuse pyrolysis gasification is a kind of endothermic reaction process, need to have and successively rubbish is heated.Refuse gasification institute
The heat needed, along with the first combustor 10 burns, caused heat provides heat as caused by incineration firing.Can be by this
Rubbish handled by incinerator is divided into 2 classes：A, for carried out after pyrolytic gasification burn processing rubbish, account for garbage disposal total amount
85%；B, 15% rubbish that remaining moisture content is less and composition containing combustible is more carries out burning processing in heating chamber 2, produces
Heat go for other 85% refuse pyrolysis gasification.Cracked using heat caused by the more incineration firing of combustible composition
Gasify remaining 85% rubbish, reduce cracking gasification needed for fuel, saved cost.
During work, from the input of lower furnace door 19 rubbish that moisture content is less and composition containing combustible is more to casting furnace grate 5,
Combustion air passes through outside pressure fan and enters air compartment 1 from blast pipe 15, then flows up into heating chamber 2, the first combustor 10
Start the rubbish lighted in heating chamber 2, produce heat, the rubbish in pyrolysis vaporizer 3 is gasified.
The rubbish for carrying out pyrolytic gasification is needed to be put into from upper furnace door 13 in pyrolysis vaporizer 3, in oxygen deprivation（Excess air coefficient
﹤ 0.3）It is heated under state and carries out pyrolytic gasification, caused pyrolysis gas enters pyrolysis combustion chamber 4 through pyrolysis gas passage 7, through the
The ignition of two combustor 11, when being pyrolyzed the chamber flue gas temperature of combustion chamber 4 higher than 900 DEG C, the second combustor 11 closes automatically
Machine, pyrolysis gas are lighted, continuously and stably burnt, and saved the fuel of the second combustor 11 automatically by scorching hot radiation of burner hearth heat
Consumption.When as little as 890 DEG C of chamber flue gas temperature, the second combustor automatic ignition, continue it is stable burn, it is safe and reliable to operation.
Wherein, the main function of the first combustor 10 is that igniting and increase heating chamber 2 are supplied needed for refuse pyrolysis gasification
Heat, the second combustor 11 have igniting, stable burning and ensure that the fire smoke gases temperature in pyrolysis combustion chamber 4 exists all the time
More than 890 degrees Celsius of function, the effect for the Zhong bioxin that removes smoke is reached；First combustor 10 and the second combustor 11
