pretreatment of raw coal
Molecular formula :
MW :

nature : coal gangue contains, moisture and ash, or that they processed, from the perspective of fuel use, it will lower transport efficiency, reduce boiler and equipment utilization, and increase the construction costs use and operating costs. For example, coal moisture to 0% and 25%, a difference of boiler efficiency by about 5%. In order to improve the quality of coal, according to the nature of different coals and the use of different purposes, the right of coal for coal preparation, dehydration dry ash from coal slurry and modulation handle processing, integrated to improve efficiency in the use of coal.
