One of the basic indicators of coal quality is high ash content, which indicates that the combustible components in coal are low
One of the basic indicators of coal quality is high ash content, which indicates that the combustible components in coal are low
During coking, it will reduce the strength of coke, increase the consumption of blast furnace volume, and reduce the production of pig iron
Ash content is a harmful substance. As the ash content in thermal coal increases, the calorific value decreases, the slag discharge increases, and the coal is prone to slagging; For every 2% increase in ash content, the calorific value decreases by about 100kcal/kg, ash content increases by 1%, coke strength decreases by 2%, blast furnace production capacity decreases by 3%, and limestone consumption increases by 4%.
