油页岩与煤的混烧特性研究

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.
