working principle of grinding mills in thermal power plants
How Does a Coal Power Plant Work Bright Hub Engineering
· Thermal-based power plants can produce electricity from coal or other fuel sources. The coal-fired process requires three different steps to turn energy released from burning coal to generating electricity for consumption. Coal fired power plants while producing power require a lot of water and produce a lot of pollutants like ash and CO2.

Chat OnlineThermal Power Plant Principle Parts Working
· In a thermal power plant to complete the cyclic operation we need to send water again to the economizer at high pressure. Steam exhausted from LP turbine is not in condensed form and it is not economical to compress the steam at a very high pressure around 150 Kg/cm2. So a device is needed which can condense the steam into water.
