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

Abstract

Abstract:

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.

Key words:

coal field, coal storage, storage, biological enzyme, caloric value, coal pile temperature, spontaneous ignition
