#0183;#32;For coalfired power plants, the response time of the coal mills is critical for the overall reaction time to changing demand. Flexible operation or load following requires that the output of the plant can be made to vary in accordance with demand and in accordance with allowable ramp rates.
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.

#0183;#32;Large coalfired power plants were typically designed as a base load units. Any changes in load level, as well as startup time, are noticeably slow on that kind of units. However, in order to adapt to changing market conditions with increasing number of renewable energy sources, coalfired power plants need to improve their flexibility. In the paper, 200 MWe class unit has been taken into
A pulverized coalfired boiler is an industrial or utility boiler that generates thermal energy by burning pulverized coal (also known as powdered coal or coal dust since it is as fine as face powder in cosmetic makeup) that is blown into the firebox.. The basic idea of a firing system using pulverised fuel is to use the whole volume of the furnace for the combustion of solid fuels.

In the Bexbach and Heilbronn (unit 7) hard coal fired power plants, units with an installed capacity of 750 and 800 MWeI respectively, the single coal mill/burner level operation was tested and
#0183;#32; pulverizer/mill system One of the critical power plant components that is relied upon to convert the energy stored in coal into electricity is the coal pulverizer or mill. The coal flow is controlled by the feeder, allowing coal to flow into the pulverizer mill. The pulverized coal and air mixture is then transport to the boiler burner panels.
#0183;#32;A typical MPS89 pulverizer found in many coalfired power plants. Combustion of coal particles beneath the grinding zone is not a serious problem, as long as the mill is in operation.

There are many types of mills and bowl mill is one of them, all these mills can face coal hangup. For taking corrective action during a coal hangup in bowl mills the operator will have to know the reason for such a hangup, how the plant will respond, what he has to respond to and what the local operator will have to do. This will reduce the chance of mill trip and bring back boiler to
