摘要
就添加煤灰对低灰高挥发分煤发热量的影响,及煤灰添加量和煤灰中硫含量对煤发热量的影响进行研究.结果表明,添加煤灰可有效解决低灰高挥发分煤测发热量时易喷溅的问题.煤灰中硫含量对煤发热量的影响较小,煤灰加入量为0.1g/g煤时,可保证测量的准确性和可靠性.
The impact addition coal ash on the calorific value of low ash and high volatile coal was studied.The influence of the amount and the sulphur content of coal ash on calorific value of coal was investigated.And the results showed that the problem of splashing of low ash and high volatile coal during calorific value test was effectively solved by addition coal ash.And there was a little effect of calorific value with sulphur content in coal ash.The quantity of coal ash was confirmed 0.1 g/g coal,while the calorific value of coal can ensure the accuracy and reliability.
