升温速率对生物质与煤共热解特性影响的试验研究

Experiment for Heating Rate on Pyrolysis Characteristics of Biomass-coal Mixture

摘要: 采用热重分析法，在不同升温速率下，对生物质、煤以及生物质与煤的混合物进行热解试验，分析了升温速率对热解过程的影响，研究了生物质与煤热解特性的差异以及他们共热解时生物质对煤热解过程的影响。试验结果表明，随着升温速率的升高，热重曲线向温度高侧移动，生物质与煤的热解特性差异很大，并且在生物质与煤混合热解时，总体热解特性分阶段呈现生物质与煤的热解特性。

Abstract: The pyrolysis experiment on biomass, coal and biomass-coal mixture with various heating rates were carried out and analyzed by thermo-gravimetric analysis method. The effects of heating rates on the process of pyrolysis characteristics of biomass, coal and biomass-coal mixture were obtained and analyzed. The experiment results showed that the thermo-gravimetric curves move to the high-side of temperature while heating rate increases, there is a large different characteristic between biomass and coal, and the pyrolysis characteristic of biomass-coal mixture occur separately the characteristics of biomass or coal at different stages.
