Abstract:
China produces nearly seven hundred million tons of straw a year, about one third of them are directly burned after harvest in the farmland. This causes serious problems on environmental pollution and resource squander. In addition, Chinese farmlands are distributed; gathering of these resources is a waste of time and money. Thus, to solve these problems, small-scale, distributed applications are preferred. Gasification is an important utilization technology of biomass energy. Biomass gasification system for power generation is an effective method. Therefore, we developed a demonstration system of a 60kwe biomass gasifier connected with an internal combustion engine electricity generator. This gasifier has a wide-ranging adaptability of feed stocks; even simply cutted rice straw can be used without shaping into pellets. The innovative design, construction, and operation are presented detail in this paper. The influence of material quantity, equivalent ratio on gas yield rate, carbon conversion rate and gasification efficiency are detected. The product gas composition and its LHV are analyzed simultaneously.
