Coal type determines the composition of coal and it reflects the degree of oxidation during coalifiion. Based on the van Krevelen diagram (van Krevelen, 1993), coal consists of three key material groups including vitrinite, liptinite and inertinite, which are composed of distinct constituents called macerals. Table compares the key characteristics of coal macerals (van Krevelen, 1993).

A line diagram of ball mill using two classifiers is shown in figure. It consists of a slowly rotating drum which is partly filled with steel balls. Raw coal from feeders is supplied to the classifiers from where it moves to the drum by means of a screw conveyor. As the drum rotates the coal get pulverized due to the combine impact between coal and steel balls. Hot air is introduced into the ...

A simplified block flow diagram (BFD) ... The pulverization of coal is performed in the coal mill, while the hot flue gasses from PH (Hfg 4) are used for preheating and drying of the raw coal. The stream of preheated coal (Fl ph) is then transferred into the rotary kiln burner. A planetary clinker cooler (CC) is used to cool down the clinker from approximately 1400°C to 100°C. The planetary ...

Most coals, as they are dug from the ground, have some amount of moisture associated with them. Gentle heating of coal at a temperature slightly above the boiling point of water causes a loss of weight from the sample that is defined as moisture. The moisture content of coals ranges from about 5% to almost 70%. Moisture is an undesirable ...
Mill Control The Mill Control is a set of logic that regulates each pulverizer on the unit and sets the amount of coal fed to the mill, the amount of primary air flowing through the mill, and the temperature of the coal/air mixture leaving the mill. The mill control strategy is dependent upon the type of mill being used on a particular unit.
· Schematic diagram of coal mill The mass of coal to be pulverised depends on the mass flow of the raw coal,, the return flow of the particles rejected by the classifier,, and the grinding rate which is proportional to the mass of raw coal on the grinding table, . (1) The mass of pulverised coal on the table depends on the grinding rate and the amount of coal picked up by the primary air from ...
by summing the coal flow for each mill. The type of coal flow measurement varies from plant to plant, and may be derived from feeder speed, mill differential, feeder demand, etc. A mill model is included to more accurately convert the coal flow measurement into a representation of the energy release in the furnace. The coal flow is converted to a BTU value and is calibrated on line using the ...
· 1. INTRODUCTION Coal mill is an important component of the thermal power plant. It is used to grind and dry the moisturized raw coal and transport the pulverized coal 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 frequent shut down.
