生物酶处理对煤炭存储热值及堆煤温度影响的试验研究

Experimental study on the effect of biological enzyme treatment on coal storage calorific value and coal pile temperature

电厂煤场储煤量巨大,储存期较长,减少煤炭在存储过程中的热值损失和自燃现象,能够提高电厂的经济效益。通过在某煤场煤堆喷洒生物酶,获得了生物酶在大规模煤堆上使用时对煤堆热值及温度的影响数据。结果表明,生物酶处理技术对于降低煤炭储存过程中的热值损失有一定效果,经处理的煤堆储存期温度升高,不利于减少煤堆的自燃。

The coal storage of the power plant coal yards is huge,and the storage period is long. Reducing the loss of calorific value and spontaneous combustion of coal during storage period can improve the economic efficiency of power plants. Through spraying biological enzymes on the coal pile of a coal yard,the data of effect of biological enzymes treatment on large-scale coal pile calorific value and temperature is obtained. The results show that the biological enzyme treatment technology has a certain effect on reducing the loss of calorific value during the coal storage period. The temperature of the treated coal pile during storage period will rise,which is not conducive to reducing the spontaneous combustion of the coal pile.
