摘要
将玉米秸秆与煤进行不同比例的混合得到相应的混合燃料,通过对其进行工业分析,得到不同比例混合燃料的挥发分、固定碳、硫含量、发热量、灰分,对工业分析各组分值进行方程拟合,分析玉米秸秆掺入比例对混合燃料各组分的影响。结果表明:混合燃料的挥发分、固定碳、硫含量、发热量、灰分与玉米秸秆掺入比例的变化均呈线性关系,但变化幅度不相同。通过对混合燃料进行工业分析,并对各组分与玉米秸秆掺入比例的变化进行方程拟合,比较准确地得出了混合燃料各组分的变化率和变化趋势,为生物质和煤混合燃料的发电利用提供了一定的参考。
Blend fuel of corn stalk and coal was made in a series of blend ratios with corn stalk.Several data were gotten by proximate analysis with considering indexes of volatile matter,fixed carbon,sulfur content,heat value and ash.The regression equations of the data were gotten through regression analysis for the relationship between blend ratios of corn stalk(BRCS)and proximate analysis data(PAD).The result showed that there was linear relation between PAD of the blend fuel and BRCS,and linear equation slope absolute value of volatile matter,fixed carbon,sulfur content,heat value and ash were 8.49,7.64,5.45,4.85,3.97,respectively.Volatile matter content increased with the increase of BRCS,and other PAD was opposites.Variation rate and variation tendency of the blend fuel PAD was gotten through proximate analysis and fitted equation,and some references may be provided for power generation using blend fuel of biomass and coal.
