Boiler Feed Water Pump Working Principle and Operation

Jul 18, 2018 · Boiler feed water pumps are commonly centrifugal pumps. To ensure a high enough head and pressure, Boiler feed Pumps have been arranged in series (multistage pumps). A feedwater pump is most often driven by an electric motor for energy efficiency. Often two steam turbine-driven (turbo pump) and two electric feedwater pumps are used

Proper Boiler Feed Water Temperature Management | Powerhouse

Pre-heating the feed water to achieve an ideal boiler feed water temperature will allow the boiler to run most efficiently as the heat input required to raise the temperature of the water up is reduced. The difference between 140°F and 180°F in boiler feed water temperature equates to about a 3-4% difference in boiler efficiency.

The Importance of Boiler Water and Steam Chemistry

At a minimum, boiler feedwater must be softened water for low pressure boilers and demineralized water for high pressure boilers. It must be free of oxygen and essentially free of hardness constituents and suspended solids. Recommended feedwater limits are shown in Table 1. Use of high purity feedwater minimizes blowdown requirements in drum

High Pressure Boiler: What is it? Types & Characteristics

The division of megapascal pressure (MPa) determines whether a boiler is low and high pressure. Boilers that produce pressure above 80 MPa are considered to be high pressure. Low pressure boilers have a MPa below 80 MPa. Water circulation can be forced or natural. If the water is pumped, it is forced.

Difference Between Low- and High-Pressure Boilers | Hunker

A boiler is an appliance designed to heat water and produce energy. The heat is applied to water in an enclosed container before being distributed throughout the system. The major difference between a low-pressure and a high-pressure boiler is the amount of pressure per square inch and pounds per square inch gauge that the boiler produces.
