    • Overview· PDF fileThe coal-feed hopper runs along the entire coal-feed end of the furnace. Acoal grate is used to control the rate at which coal is fed into the furnace, and to control the thickness of the coal bed and speed of the grate. Coal must be uniform in size, as large lumps will not burn out com-pletely by the time they reach the end of the grate. As the bed thickness decreases from coal- feed end to rear end, different …

Boiler feed water and booster pumps | Sulz

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.

Gravimetric and Volumetric Coal Feed Systems for Boile

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.

    Characteristics of boiler feedwater - Lennte

    • OverviewA low-pressure fire-tube boiler can usually tolerate high feed-water hardness with proper treatment while virtually all impurities must be removed from water used in some modern, high-pressure boilers. Only relatively wide ranges can be given as to maximum levels of alkalis, salt, silica, phosphates etc, in relation to working pressure.

Thermal power station - Wikiped

The boiler furnace auxiliary equipment includes coal feed nozzles and igniter guns, soot blowers, water lancing, and observation ports (in the furnace walls) for observation of the furnace interior. 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.

Boiler Feedwater - an overview | ScienceDirect Topi

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 …

Mechanical stoker - Wikiped

A mechanical stoker is a mechanical system that feeds solid fuel like coal, coke or anthracite into the furnace of a steam boiler. 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.
