Many of the existing pulverised coalfired (PCF) power stations are operated at a fixed steady load ( baseload operation). There is however a growing requirement for load following or flexible operation, which requires flexibility in most of the components of the power station. Flexibility and efficiency can be improved by close control of the coal []
Coal mill is an important component of the thermal power pla nt. It is used to grind and dry the moisturized raw coal and transport the pulverized coal #177; air mixture to the boiler. Poor dynamic performance of coal mill will lead to decrease in the overall efficiency of the power plant, slow load take up rate and fr equent shut down.

The liners are fastened to the inner side of mill shell (cylindrical part) to protect the shell from the impact of the steel balls. There are 600 liners of ten variants in each shell weighing tonnes. The original lift value of the liners is 55 mm. and the minimum lift allowed is 20 mm.
#0183;#32; Mill Bowl mills are employed to pulverize the precrushed raw coal to the required fineness before it is admitted into the boiler furnace for combustion. The mill output can be easily varied, as per the turndown ratio from its minimum to maximum load. Crushed raw coal at a controlled rate is fed into the revolving bowl of the Bowl Mill. Centrifugal force feeds the coal uniformly over

To summarize the coal mill controls, they may be divided basically into two major categories:. 1. To control the quality of coal being sent to the burners located on the furnace walls. The word quality here means the temperature and fineness of the PF. The set temperature values are dependent on the percentage of volatile matter that exists in the main fuel.

A raw mill is the equipment used to grind raw materials into quot;rawmixquot; during the manufacture of cement. Rawmix is then fed to a cement kiln, which transforms it into clinker, which is then ground to make cement in the cement raw milling stage of the process effectively defines the chemistry (and therefore physical properties) of the finished cement, and has a large effect upon the
Bowl mills are used for pulverizing 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.
#0183;#32;The crushed coal is then transported to the store yard. Coal is transported to bowl mills by coal feeders. 3. Bowl Mill. The coal is pulverized in the bowl mill, where it is grounded to a powder form. The mill consists of a round metallic table on which coal
