摘要
利用高温导热系数测试仪、TGA/DSC1同步热分析仪研究了罐式煅烧炉煅后焦的导热系数、比热容等热物理性能。结果表明:随着温度的升高,煅后焦的导热系数和比热容均升高,当温度超过200℃时,导热系数和比热容均出现异常变化,煅后焦的氧化起始点为200℃;对导热系数实验数据进行了回归分析,得到了煅后焦的导热系数实验关联方程。
Thermo - physical properties of calcined petroleum coke were studied by coefficient of heat conductivity testing instrument and TGA/DSC1 syn chronization thermal analyzer. The results showed that the coefficient of heat conductivity and specific heat of calcined petroleum coke increased with the temperature increasing. When the temperature exceeded 200℃, the coefficient of heat conductivity and specific heat capacity were unconventionality. The oxidating point was 200℃. An equation was obtained based on the experimental data.
