POWER PLANT BYPRODUCTS Three general classes of byproducts from electric power plants can be used in the manufac-ture of portland cement: fly ash, bottom ash/boiler slag, and flue gas desulfurization (FGD) materials. Fly ash and bottom ash/boiler slag contain large amounts of silica and alumina as well as calcium and iron [TFHRC 2002].
objective of plant chemical control. The method of maintaining steam purity depends on the manner in which the steam is produced. Plants with drum-type steam generators — both conventional boilers and heat recovery steam generators (HRSGs) — maintain steam purity by taking advantage of the physical separation that occurs

The energy efficiency of a conventional thermal power station is defined as saleable energy produced as a percent of the heating value of the fuel consumed. A simple cycle gas turbine achieves energy conversion efficiencies from 20 to 35%. Typical coal-based power plants operating at steam pressures of 170 bar and 570 °C run at efficiency of 35 to 38 %, with state-of-the-art fossil fuel
Water Treatment for High Pressure Boilers in Sugar Plants Impurities present in water used for steam generation and other power plant and process (or absence) of pretreatment equipment; chemical treatment added to a boiler to condition these impurities often will contribute to boiler deposits.

A fossil fuel power plant (FFPP) (also known as steam electric power plant in the US , thermal power plant in Asia , or power station in the United Kingdom (UK) is an energy conversion center designed on a large scale for continuous operation. Just as a battery converts relatively small amounts of chemical energy into electricity for temporary or intermittent use, the FFPP converts the energy
power plant boiler steam drum internals Boiler steam drum is very important part of any power plant .it is also called "heart of boiler "Because of its importance in steam generation. Boiler steam drum acts as reservoir which provides necessary head for circulation of water through evaporation zone.
