摘要
采用热重分析仪,对糠醛渣和烟煤、褐煤以及它们以不同比例所得的混合试样进行燃烧特性实验,结果表明:在煤中加入糠醛渣后,混合试样和煤相比其着火温度提前,综合燃烧性能显著提高,糠醛渣与褐煤混合比糠醛渣与烟煤混合具有较好的燃烧性能,且当糠醛渣与褐煤以2∶1的比例混合时混合试样的燃烧特性较好;最后通过数据分析,求解燃烧反应的动力学参数,为糠醛渣的经济利用提供了可靠的理论依据.
Combustion properties of furfural residue, bituminous coal and brown coal of themselves as well as a sample of the above items mixed in different proportions are studied with a thermogravimetric analyzer. The results show that the ignition temperature of the blends is lower than the ignition temperature of burning coal, the comprehensive combustion performance is obviously increased. The combustion behavior of furfural residue mixed with brown coal is better than furfural residue mixed with bituminous and the combustion behavior is good when furfural residue mixed brown coal at the proportion of 2 ： 1. Based on data analysis, the kinetics parameters of combustion reaction are achieved. It provides a stable theory foundation for economical application of furfural residue.
