Abstract

The invention discloses a residual heat-based coal drying system. The system comprises a residual heat oven and a coal conveyor which are connected with each other; and coal is conveyed into the residual heat oven through the coal conveyor for closed drying treatment. Because the temperature of the coal rises, sufficient combustion of the coal dried by the system is facilitated, and the coal consumption is greatly reduced. Furthermore, the coal grinding quality is remarkably improved.

Description

technical field [0001] The invention relates to the fields of energy saving, emission reduction and green environmental protection, in particular to a coal drying system based on waste heat. Background technique [0002] At present, the waste heat discharged by industries in our country can be seen everywhere, and a lot of waste heat is not well utilized, and most of the combustion methods are still coal-based. Most of the coal contains more than 10% free water, and the internal water contained is also about 10%. , so coal has to evaporate about 20% of the water during the combustion process, which greatly reduces the calorific value of coal and causes a lot of energy waste. Contents of the invention [0003] In order to overcome the problem of energy waste, the present invention provides a coal drying system based on waste heat. Based on the present invention, the waste heat discharged from industry can be fully utilized to dry coal, which is conducive to the full combust...
