Description

technical field [0001] The invention relates to a device and process for comprehensive utilization of waste, in particular, to a device and working method for comprehensive utilization of low-quality coal, biomass and solid waste. Background technique [0002] During the production and processing of coal, a large amount of low-quality coal will be produced, and its utilization rate is low or even discarded. Large quantities of biomass produced in nature are also often placed on hold. A large amount of solid waste will be generated in the process of resource extraction and production. The above-mentioned low-quality coal, biomass and solid waste not only reduce the utilization rate of resources, but also cause certain environmental problems. If it is utilized, there will be great development potential. At present, some efficient and clean technologies have been used to utilize these fuels, but there are also problems such as low conversion efficiency of equipment and singl...
