fire ammonia and pulverized coal aimed at reducing CO 2 emissions from coal-fired power plants. Not only CO 2 emissions but also ash accumulation in the furnace, ash disposal, and sulfidation corrosion can be reduced by changing part of the fuel used in a coal-fired power plant from coal to ammonia. However, doing so raises
In coal milling for power stations, a 'closed-loop' process is used in which the rejects from the classifier are returned to the mill for regrinding. In VSMs, the re-circulation loop is within the mill, but some mill types would have an external loop. In fact, there are a number of re-circulation loops within a mill system.
