Description

technical field

[0001] The invention relates to a biomass pyrolysis polygeneration system, which is suitable for continuously converting biomass into high-value products such as charcoal, gas and oil. Background technique

[0002] The important task of new rural construction is the construction of new rural energy system, and the comprehensive and efficient utilization of abundant biomass resources in rural areas is one of the important means to accomplish this task. Modern biomass utilization technologies, such as combustion power generation, gasification power generation or gas production, have been utilized in rural areas, but the unique defects of biomass resources - wide distribution of resources, low energy density, and difficulty in collection have led to the current use of a single product Biomass utilization technology based on large-scale operation is difficult to meet the requirements of new rural energy construction. Biomass polygeneration technology can produce...
