coal-fired thermal power station is a power plant in which the prime mover is steam driven. water is heated, turns into steam, and spins a steam turbine, which drives an electrical generator, as schematically shown in fig. 1.9.after it passes through the turbine the steam is condensed in a condenser and recycled to where it was heated; this is known as a rankine cycle.
mills commenced. atrita pulverizer design the atrita mill is an attrition type, high speed and compact designed pulverizer. for over years, the atrita mill has been used for coal firing boilers to pulverize a wide range of fuels including eastern and mid-western bituminous coals, sub-bituminous coals, lignite and delayed coke. there are
