Abstract:

In order to rationally and effectively utilize various biomass and solid waste resources in China, biomasscoal coupled power generation is proposed. However, due to the high investment and lack of subsidy policy for electricity price, the promotion is very difficult. Matching the production of various biomass and solid wastes up with the conventional operational parameters of thermal power units, and comparing the investment of biomasscoal coupled power generation projects with conventional biomassfired projects, a reasonable solution is proposed. It is suggested that municipal sludge can be directly blended and burned, which is economical and convenient.The biomass burning system with circulating fluidized bed boiler is simple and moneysaving in blending and combustion.The biomass burning system with pulverized coal boiler is complex and moneyconsuming,which can be improved by biomass gasification and byproducts making.General industrial solid waste from cities can be blended and burned in circulating fluidized bed boilers, but the impact on environment needs to be analyzed.
