From the angle of technical analysis, the combustibleconstituents of biomass is made up of volatile matter and fixed carbon two portions, and in order to obtain high-quality biological charcoal, most ideal response state is by volatile matter in biomass burning as far as possible, for pyrolytic gasification provides energy, avoid the scaling loss of fixed carbon.Volatile combustion and fixed carbon burning can be there is simultaneously in the pyrolytic gasification process taking air as vaporized chemical, need to add the oxygen that other inflammable gas is tried one's best in consumed cabin air.Hot combustion gas is adopted to be transmitted back to mode bottom fluidized bed pyrolysis vapourizing furnace in the utility model, utilize the rate of combustion of hot combustion gas far above the feature of fixed carbon rate of combustion, consume oxygen unnecessary in air, reduce fixed carbon scaling loss, simultaneously for pyrolytic gasification provides energy.
In the higher situation of biomass material moisture content, the biological fuel gas calorific value that gasification produces only has about 2000kJ/Nm3, adopts conventional combustion manner to burn.Utilize biological fuel gas to be the hot combustion gas feature of more than 500 DEG C in the utility model, directly hot combustion gas is passed into adiabatic fuel gas with low heat value combustion chamber, pass into the high temperature air of preheating simultaneously, realize the thorough after-flame of fuel gas with low heat value.The Energy harvesting vapour generator that fuel gas with low heat value burning produces and air preheater absorb, and improve system efficiency.
The above is only preferred implementation of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
