油页岩与煤的混烧特性研究
-
摘要: 使用STA409型热综合分析仪进行了桦甸油页岩与高硫合山煤的混烧特性实验研究，得到了油页岩和高硫煤混烧的TG和DTG曲线，分析了不同Ca/S对油页岩和高硫煤混烧特性的影响规律，同时运用Freeman-Carroll法计算得到了不同Ca/S下的油页岩燃烧特性化学反应动力学参数。研究表明，在高硫煤中加入少量的油页岩，高硫煤的燃烧特性有所改善，燃烧特性趋好；油页岩的加入使得高硫煤低温段的燃烧产物初析温度降低，着火温度提前；在高硫煤中加入20%左右的油页岩作为可燃脱硫剂从燃烧角度讲是切实可行的。Abstract: Using thermal synthesis analyzer experimental research on the combustion characteristic of Huadian oil shale and Heshan coal mixture was studied. The effect of different Ca/S ratio on the combustion characteristic of the mixture was analyzed using the Thermal Gravity (TG) and Differential Thermal Gravity (DTG) curves. The kinetic parameters of combustion were obtained with Freeman-Carroll method. The results showed that the combustion characteristic of Heshan coal with small amount of oil shale added was improved. The initial temperature of pyrolysis of Heshan coal was decreased and the ignition temperature was lowered. About 20% of oil shale added in Heshan coal is feasible for desulfurization of the mixture during combustion.
