Biomass particle gasification process for kiln

Abstract

The invention discloses a biomass particle gasification process for a kiln, which comprises the following steps of: smashing and pressing sawdust and wood shavings into biomass particles; adding the biomass particles into a biomass gas gasification furnace according to certain weight to carry out a thermalization cracking reaction to generate mixed gas by controlling the burning temperature in the furnace to be 900-1,200 DEG C; spraying the outlet mixed gas, and introducing the sprayed gas into a purifier for heat exchange; cooling, then introducing the gas into a cyclone chamber, and separating out ash content in the gas under the action of cyclone separation; and introducing gas after the cyclone separation into a separator, and under the condensation action of the separator, further separating out clean gas and liquid residues by controlling the clean gas output temperature to be 20-25 DEG C. Compared with the prior art, the biomass particle gasification process for the kiln has the advantages of high energy conversion ratio, high gas heat value, good purification effect, low tar content, large gas output and uniform gas outlet.

Description

technical field

[0001] The invention relates to the technical field of gasification of biomass materials to produce gas, in particular to a process for producing gas by carbonizing or coking the gasification of biomass solid materials, and purifying the combustible gas generated by gasification . Background technique

[0002] Biomass refers to various organisms produced through photosynthesis using the atmosphere, water, and land. The abundance of biomass resources and the coercive demand for new energy around the world make the development of biomass resources a new energy construction in recent years. Hot topics. In order to make full use of renewable biomass resources and reduce environmental pollution, the use of biomass resources is mainly to gasify biomass raw materials to generate combustible gas to replace traditional natural gas to obtain clean energy. Biomass gasification technology It is of great significance to establish a sustainable energy system, promote na...
