The fineness of the milling product and the capacity of the pulverizer are strictly connected. With increased fineness grows the overall circulation rate of coal in the mill, coal retention time and the flow resistance. As a result, the maximum mill capacity decreases and the rate of change of operational parameters of the furnace system deteriorates. In extreme cases, the performance of the boiler may be limited, and therefore improving the fineness of milling

coal is received from a number of sources and stored in semi-segregated piles. The coal is removed from these piles and loaded into the mill silos. Each silo feeds a pulverizer, and usu-ally has a storage capacity of about eight hours. The main goal for a power plant is make sure that the most economic coal

Nov 01, 2009 The velocity data is that of the moving coal particles. See Figure 3. Air velocity in these pipes ranges from 110 to 120 fps. The difference between the air and coal velocities is the coal slip.
Aug 01, 2015 The operating window , specifies the safe operational limits for an individual mill in terms of the coal flow and air flow, such that if these constraints are obeyed during the operation, mill problems such as coal choking, erosion, fire or explosion in pulverized coal-air pipes or inside the mills can be avoided. The diagnostic system evaluates the condition of the mill by checking the proximity of the present working point of the mill
