Problems solved by technology

The chemical energy stored in these biomasses is more than three times the world's total energy consumption, but our current utilization rate is less than 3% of the total
There are many defects in the existing biomass gasification process operation methods, such as: simple operation methods, inability to accurately control each reaction stage, high operating costs, high possibility of operational errors, low safety, uncontrollable gas composition, and smoke exhaust time long, pollutes the environment, unstable gas production, high tar content in gas production causes blockage of gas pipelines, or damages and corrodes terminal application equipment
Therefore, it cannot be used continuously for a long time, it is not convenient for storage and transportation or large-scale promotion and application, and it cannot be applied to continuous and stable power generation of existing gas-fired generator sets

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...
