生物质与煤的混合燃烧实验研究

为了解生物质和煤的混燃特性,利用热天平对生物质、煤及其混合试样进行了热重实验研究,考察各试样的着火温度、燃烧速率最大时温度、燃尽温度和最大燃烧速率等燃烧特征参数,并对实验数据进行了分析处理,求出了反应的动力学参数活化能E和频率因子A.结果表明,同烟煤比较,生物质有较低的燃烧特征温度和较快的燃烧速率;在烟煤中加入生物质共燃后,着火燃烧提前,同时可以获得更好的燃尽特性.

Experimental Research on Co-combustion of Biomass and Coal

In order to obtain the co-combustion properties of biomass and coal, the thermal gravimetric analyses were used to study the properties of blended samples, the combustibility characteristic parameters such as ignition temperature, peak temperature at maximum weight loss rate, burnout temperature, and maximum rate of combustion would be investigated.After dealing with experimental data, the kinetics parameter E and A were obtained.The experimental results show that the lower ignition temperature and better b...
