Boiler Feed Booster Pumps & Balancing Axial Thrust | Pumps

Dec 08, 2017 · Q. What is a boiler feed booster pump, and why are they required in some power plants? A. Large fossil fuel power plants use high pressure and temperature boiler feed systems, which generally require large or high speed boiler feed pumps with controlled-compression gasketed joints. This is accomplished by selecting pumps of either barrel (BB5) (see Figure 3.8) or ring-section (BB4) design.

Boiler feed water and booster pumps | Sulzer

Feedwater pump for high differential heads. 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.

Steam Boiler Feed Pumps & High Pressure Boiler Feed Water

Industrial boilers, for example on board a marine vessel, in a large industrial factory or power plant, are fed either fresh water or steam by a high pressure boiler feed pump. As the water or steam is fed round a system, they are sometimes referred to as boiler circulation pumps. As taking suction from a condensate system is a high pressure application, steam boiler feed pumps are generally high head, low flow pumps, making multistage pumps …

How to increase water pressure in a shower with a combi boiler

Ideally, the combi boiler flow rate for a good shower should be at least 12 - 15 litres a minute. The flow rate simply refers to how much water can pass through the appliance to feed taps and showers once the boiler is working. Choosing a powerful combi boiler with a good flow rate will help you to optimise hot water pressure around your home.
