Feed water pumps (FWP) pump the feed water from the de-aerator through the HP heaters to the boiler. The major characteristic of FWP is their high differential head. In medium to large size coal- and oil-fired power plants, the main FWP are horizontal barrel type while booster pumps are horizontal single stage double suction type.
lexie@zozen.com > Get A Quote >The gravimetric feeder compensates for the variation in bulk density and feeds a fixed weight of coal in response to a boiler fuel demand. This ability to accurately weigh the coal provides significant improvement over volumetric types in terms of matching the fuel delivered by the feeder to the actual process energy required on coal fired units.

Furnace explosions due to any accumulation of combustible gases after a trip-out are avoided by flushing out such gases from the combustion zone before igniting the coal.
lexie@zozen.com > Get A Quote >High purity water is required as boiler feed water for steam generation during electricity production using steam turbines to protect the boiler tubes and turbines from corrosion, scale formation and structural defects. In conventional power plants – oil, coal, natural gas, nuclear – steam is generated at a pressure of 40–200 bar g and fed to a turbine, which converts the heat energy to mechanical energy that in turn …

They are common on steam locomotives after 1900 and are also used on ships and power stations. Known now as a spreader stoker they remain in use today especially in furnaces fueled by wood pellets or refuse.
