Description

technical field [0001] The invention relates to the technical field of producing combustible gas by pyrolysis and gasification of biomass, and further relates to the field of clean energy for producing combustible gas by pyrolysis and gasification of waste polymer compounds. Background technique [0002] With the decreasing reserves of traditional fossil energy (coal, oil, natural gas) and the environmental pollution caused by the use of fossil energy, it directly threatens the survival and development of human beings. Biomass is a kind of renewable energy with abundant reserves, and its use as an alternative energy source can realize CO 2 Zero emission, and the low content of S and N in it can greatly reduce the greenhouse effect and environmental pollution. Recently, there have been many researches at home and abroad on biomass pyrolysis gasification to produce combustible gas, and the use of plasma technology in coal gasification, natural gas cracking to acetylene, and p...
