基于模糊数学的玉米秸秆与煤混合燃料特性分析

Analysis of Characteristics of Corn Stalk-and-Coal Mixed Fuel Based on Fuzzy Mathematics

为了对玉米秸秆和煤混合燃料特性进行综合评价,结合模糊数学对混合燃料的工业分析结果进行了分析.将质量分数为10%～90%的玉米秸秆与煤混合制成混合燃料,综合考虑了混合燃料的挥发分、发热量、硫含量、灰分、燃料价格等指标,通工业分析得出了基本数据,依据模糊数学决策法对数据进行分析,得出不同混合比例下的混合燃料综合性能并进行了比较,为生物质和煤混合燃烧利用提供一定的参考.

Research was conducted on proximate analysis data of mixed fuel of corn stalk and coal based on fuzzy mathematics to make the synthesis evaluation for fuel characteristics of the mixed fuel.The experiment of mixed fuel was carried out in a series of mixture ratios with corn stalk mass percent ranging from 10 % to 90 %.Several data were gotten by proximate analysis with considering indexes of volatile matter,heat value,sulfur content,ash,fuel price.The data was analyzed through fuzzy mathematics method,and synthesis characteristics of mixed fuel in different mixture ratios were calculated and compared.Some references may be provided for co-combustion utilization of biomass and coal.
