UNIT1 THERMAL POWER STATIONS Introduction
India has large deposit of coal (about 170 billion tonnes), 5th largest in world. Indian coals are classified as AG grade coals. In Steam power plants, the heat of combustion of fossil fuels is utilized by the boilers to raise steam at high pressure and temperature. The steam so produced is used in driving the steam turbines or sometimes steam engines couples to generators and thus in ...
Coal Grinding
However, the provision for inertization of coal mill circuit and fine coal bins (with CO2, N2 or CO2+N2 to replace O2 which promotes spontaneous ignition of fine coal) is strongly recommended to be available. Gas analyzers and explosion vents are essentially provided in mill circuits to monitor the potential of fire/explosion and mitigate fire/explosion incident respectively. Drying and ...

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 ...
Coal handling plant in a thermal power generating station
· 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 particles fall. This table is rotated with the help of a motor. There are three large steel rollers, which are spaced 120" apart. When there is no coal, these rollers do not rotate but when ...
