基于CO2气体释放法的煤燃烧特性研究

A new low-cost apparatus used to study the character of coal combustion in place of thermograimetric analyzer was developed based on the CO2 release. In order to prove the new idea, CO2 concentration of four coal samples during ignition, combustion and burnout was measured by means of the apparatus developed by the authors. The characters of special machanism based on the relation between the temperature and CO2 concentration (t-CO2), also the derivative curve Dt-CO2 were obtained. The change of CO2 can indirectly estimate the coal combustion characters.
