Operation and maintenance schedule of a steam turbine

Working Principle. Both gas and oil fired boilers use controlled combustion of the fuel to heat water. The key boiler components involved in this process are the burner, combustion chamber, heat exchanger, and controls. The burner mixes the fuel and oxygen together and, with the assistance of an ignition device, provides a platform for combustion.

An introduction to steam generation and distribution

1.1.2 Boiler " A boiler generates steam at the desired pressure and temperature by burning fuel in its furnace. Boilers are used in both fossil-fuel and nuclear-fuel electric generating power stations. A boiler is a complex integration of furnace, super heater, reheater, boiler or evaporator, economizer, and air

Working Pressure and Temperature Boilers are classified as either low pressure or high pressure and are constructed to meet ASME Boiler and Pressure Vessel Code requirements. Low-pressure boilers are limited to a maximum working pressure of 15 psig (pound-force per square inch gauge) for steam and 160 psig for hot water (2).

Basic Layout and Working of a Thermal Power Plant

Boiler blowdown is water intentionally wasted from a boiler to avoid concentration of impurities during continuing evaporation of steam. The water is blown out of the boiler with some force by steam pressure within the boiler. Bottom blowdown used with early boilers caused abrupt downward adjustment of boiler water level and was customarily expelled downward to avoid the safety hazard of

Chemical Recovery Boilers in Pulp and Paper Plants - Part

Almost two third of electricity requirement of the world is fulfilled by thermal power plants (or thermal power stations).In these power stations, steam is produced by burning some fossil fuel (e.g. coal) and then used to run a steam turbine.Thus, a thermal power station may sometimes called as a Steam Power Station.After the steam passes through the steam turbine, it is condensed in a
