Our coal pulverizer maintenance program has the following goals.
RPM has experience rebuilding and repairing many key components of different types of coal pulverizer systems including CE MPS FW BampW or hammer mills and others If you have a specific coal mill not listed above Contact Us We may already support your mill or we may be able to engineer a solution specific to your needs.
Some of our key areas of expertise with rebuilding and maintaining coal pulverizer systems are outlined below.
2 Coal pulverizermill 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.

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.

Coal pulveriser mills coal mill pulveriser lube oil The pulveriser grinds the coal to dust in rotating grinding rollers and sieves so that it can be used as fuel The pulveriser lube oil is subjected to extreme levels of very fine particles and many power plants believe the.
Boilers for steam generation in power plants and process industries use coal as fuel The percentage of boilers operating with coal as fuel outnumbers the boilers using all other fuels combined Coal is pulverized before firing for achieving a stable and efficient combustion Many types of pulverizers are used in boilers by different designers.
Pulverized coal is the most efficient way of using coal in a steam generator The coal is ground so that about 70 will pass through 200 mesh 0 075 mm and 99 will pass through 50 mesh 0 300 mm A pulverized coal boiler can be easily adapted for other fuels like gas if required later without much difficulty However during the design stage it is possible to make boilers firing multiple fuels With pulverization technology large size boilers could be designed manufactured erected and run much more efficiently.
Mainly there are three types of pulverizer used in industry the slow speed mills like ball tube mills the medium speed mills like bowl ball and race roller mills fall in this category and the third type is the high speed impact mill The slow speed and medium speed mills are selected for coals ranging from sub bituminous to anthracite The high speed mills are used mainly for lignite.
While selecting a pulverizer the coal characteristics play an important role The Hardgrove index total moisture input coal size output fineness and mill wear have direct impact on the mill output.
Ball tube mills are either pressurized or suction type In the pressurized type the hot primary air is used for drying the coal and to transport the milled coal to the furnace In this type leakage in the mill area is high.
In the suction type the exhauster is used for lifting the milled coal from the pulverizer to the furnace through a cyclone The tube mills have a large circular drum with adequate ball charge which is rotated at about 70 of the speed at which the ball charge would be held against the inner surface by centrifugal force In this mill the grinding balls can be replenished on the line.
This type of mill uses a central horizontal shaft which has a number of arms and a beater of different design is attached to these arms to beat the coal to be pulverized High speed impact mills are mainly used in pulverizing lignite Today all boiler designers opt to use ball or vertical spindle mill for coal other than lignite.
While selecting the type of mill boiler designers must clearly understand the coal characteristics the overall system being used and the maintenance requirement It is always seen that if the advantage of the mill alone is considered then the overall boiler economics can prove to be different.
