There are many effects of fuel moisture on unit operation, performance and emissions. its complexity can be grinding mill coal feeders provide coal to the coal pulverizers mills where the coal is pulverized and dried. dryer coal is easier to pulverize, and less mill power is needed to achieve the same coal fineness.
Coal, lignite or petcoke are ground in the pfeiffer vertical mill by using hot gases from a hot gas generator. the grinding plant can be inerted. the raw coal is dried while being ground in the mill even if feed moisture exceeds 25. the feed size that can be handled is up to 100 mm, making two-step pre-crushing unnecessary.Milling system operation. 9/4/2013 steag o&m company 14 •continue the feeder at minimum speed and establish coal feeding into the pulveriser. coal fed into mill gets pulverized and carried into furnace thus establishing coal firing. •check for any coal power leakage from coal pipes, mills feeder area and attend the same immediately.The coal is then fed to the hmv through the feed manifold. the depth that the feed is injected should be minimized to avoid possible bypass of light particles to the tailings stream. a feed sink plate is used to direct the feed downward into the vessel so that particles do not ‘raft’ across the width of the bath.
