Abstract

The invention provides an agriculture and forestry biomass gasification power generation method, which mainly comprises three steps of agriculture and forestry biomass preprocessing, gasification andcatalytic cracking to generate burning gas, and power generation by burning gas, wherein the step of agriculture and forestry biomass preprocessing is characterized in that agriculture and forestry biomasses are smashed and dried to obtain a raw material of a specific particle size range so as to be favorable for fully utilizing the biomasses in subsequent steps of gasification, catalytic crackingand the like, the use ratio of a biomass combustion calorific value is improved, the generation of acid substances, including tar, oxysulfide, oxynitride and the like, can be reduced, and environmentpollution caused by emission can be reduced without additional processing.

Description

technical field [0001] The invention relates to the technical field of clean energy, in particular to a method for generating electricity by gasifying agricultural and forestry biomass. Background technique [0002] Agricultural and forestry biomass refers to materials such as straw, trees and other lignocellulose in the process of agricultural and forestry production, agricultural product processing industry waste, agricultural and forestry waste, and livestock manure and waste in the process of animal husbandry production. Using agricultural and forestry biomass to generate electricity is an important way of biomass utilization, and it is also a way of biomass utilization vigorously advocated and encouraged by the state in recent years. Biomass power generation technology is mainly divided into biomass direct combustion power generation, biomass mixed combustion power generation, and biomass gasification power generation. [0003] Among them, biomass gasification power ge...
