Boiler feed pump (BFP) for biomass wasteBoiler feed pumps for biomass firing power plants applications are typically small/medium ring section type. Axially split multistage pumps are also available when required. The pump size and the design pressure will depend very much of type and the output of the power plant.
Boiler feed water and booster pumpsFeed 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.
Feed water pump (FWP) for gas-firedFeed water pumps (FWP) pump the feed water from the de-aerator through the HP heaters to the boiler. The major characteristic of the FWP is their high differential head. In all sizes of gas-fired combined-cycle power plants, the FWP are horizontal ring section type; occasionally, they could also be barrel or axially split type.
Feed water pumps for solar power generationFeed water pumps (FWP) pump feed water from the de-aerator through the HP heaters to the solar steam generator. The major characteristic of FWP is their high differential head. The FWP are usually horizontal ring section type, but depending on customer requirements, they can also be barrel or axially split type.
