Abstract：Determination of calorific value of high-ash coal and high-volatile coal were analyzed. It is shown that for high-ash coal, the results of coal sample with padded asbestos wool and lens wiping paper wrapped were basically the same, combustion was fully and the error meet the “Determination of calorific value of coal” ( GB/T213-2008 ) repeatability requirements.For high volatile coal, in addition to measuring method “Determination of calorific value of coal” (GB/T213-2008) mentioned, the measurement method of reducing coal samples could be adopted.Reducing coal sample method was easy to operate, reducing test timeand increasing efficiency.
