Coal mill is used to grind, pulverize and dry coal before the coal is transmitted the boiler. The coal is feed into the coal mill via a inlet pipe so that the roller coal mill such as ball mill or vertical mill can pulverize the coal into particles.
Coal mill scheme. The coal is fed to the coal mill through the central inlet pipe, where it is pulverized by a series of large balls separated by two types of rings. The pulverized material is carried out in the mill by the flow of air moving through it. The primary air is a mixture of cold air and air heated by the preheaters.
conditions inside the coal pipe. Source: Storm Technologies Inc. The isokinetic coal sampling method, although more difficult, is the best option for determining the true mill coal fineness produced and to calculate pulverizer performance. We perform isokinetic coal sampling after the dirty air velocity probe traverses are completed.
This will reduce the chance of mill trip and bring back boiler to normal condition at the earliest possible. The reasons for coal hangup to mills can be many, like large raw coal size, jamming of feeder, jamming of coal chute from bunker due to high moisture in coal, foreign material at row coal inlet to feeder, etc.
Aug 29, 2010· Bowl mills are used for pulversing coal in pulverized coal fired boilers. The coal to the mill is fed by a coal feeder from the coal bunker. There are many type of feeders used for coal feeding like the belt feeder which can be in volumetric or gravimetric mode, the chain link feeder, the drag feeder, etc. Row coal from the yard is sized in crushers and stored in coal bunkers.
To summarize the coal mill controls, ... The raw (coal) feed enters the mill through a central delivery pipe and falls under gravity onto the Grinding Table; ... In many applications, there is an elbow, scroll or turning head in the coal pipe at the burner inlet. Such inlet devices result in ''roping'', or an uneven distribution of coal ...
