Description

technical field [0001] The invention relates to a control method of gasification equipment, in particular to a control method of biomass gasification equipment. Background technique [0002] Energy and environmental protection are two major problems that need to be solved in the world today. Most of the energy supply still relies on fossil fuels, but the various pollutants emitted during combustion make the environmental problems worse. Ironically, the fossil fuels we use come from biomass, which is actually a 100% renewable and clean energy source. In a broad sense, biomass includes all plants, microorganisms, animals, and the wastes they produce. Biomass resources are very rich, such as municipal solid waste (MSW), forest trees, agricultural waste and other carbon-rich organic materials are excellent biomass resources. Every year, 140-180 billion tons of biomass are generated on the earth due to photosynthesis based on chlorophyll. The chemical energy stored in these bi...
