Abstract

The pollutants exceeding the standard exists in the coal furnace in the current coal slime drying system. In order to solve the industrial application difficulty of coal slime in coal mine, by using low concentration coal bed methane regenerative oxidation reactor instead of coal furnace to produce the high temperature flue gas and combining with slime drying system, a low concentration coal bed methane regenerative oxidation slime drying system which is applied to coal slime drying is formed. Taking the scale of a single regenerative oxidation reactor which processing capacity is 100,000m3/h as an example, the thermal calculation of the whole coal slime drying system is carried out. The results show that the system can dry coal slime 39t/h and has a large-scale effect.
