Raw material and energy recovery from biomass

摘要

Appts. for raw material and energy recovery from biomass has an anaerobic fermentation unit, an aerobic composting unit, a gasification unit and a power generating plant (esp. a block thermal power generating plant), together with lines for (a) excess water passage from the fermentation unit to the gasification unit and/or composting unit, (b) noxious material and unreacted and low quality solids passage from the fermentation unit and/or the composting unit to the gasification unit, (c) synthesis gas passage from the gasification unit to the power plant, (d) biogas passage from the fermentation unit to the power plant, (e) air passage from the composting unit to the power plant, (f) heat transport from the power plant to the fermentation unit, (g) current supply from the power plant to the composting unit and (h) external output of heat and/or current from the appts. Also claimed is a process for raw material and energy recovery from biomass using the above appts..
