Boiler Feed Water Pump Working Principle and Operation

The boiler feed pump function is to supply pressurized feed water to the boilers maintain the water inventory at various operating loads. 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.

Boiler and Feedwater Pump Efficiency Optimization

The power plant's control system can use the high pressure differential measurement to automatically set the feedwater rate depending on the boiler load demand. At lower demand periods, less steam is used to power the steam turbine driven pump and less feedwater is consumed.

High Pressure Condensate Return (HPR) - Industrial steam

SEQUENCE OF OPERATION: Steam from the boilers is supplied to all of the corrugators. Steam in the corrugators gives up its latent heat of evaporation, and possibly smallamount of sensible heat. Resultant liquid flows by gravity to the steam traps. As the traps cycle, high temperature condensate flows to High Pressure Condensate (HPR) receiver.

Characteristics of boiler feedwater - Lenntech

Feed-water purity requirements therefore can vary widely. A 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

Why Economizer and Air Pre-Heaters are Provided in Boilers

When air pre-heater is not provided the boiler efficiency will be around 74 % only. Thus we can conserve about 20% extra fuel when we provide both economizers and air pre-heaters in boilers. Economizer. The feed water from the high pressure heaters enters the economizer and picks up heat from the flue gases after the low temperature superheater.

DESIGN AND ANALYSIS OF HIGH PRESSURE FEEDWATER

proven design methodology to design high pressure feedwater heater. The design of shell and tube configured feedwater heater requires the knowledge of a number of factors on both shell side and tube side. An exhaustive list of these items and existing standards to select these are well documented.Author: Suhas D. Ambulgekar, B. S. Gawali, N. K. Sane, Vinaykumar Kabra, Ajit GavaliPublish Year: 2016[PDF]Designing a high pressure feed water heater - ee.co.zahttps:// pressure (HP) feed water heaters are used to heat up the boiler's feed water at high pressure and temperature before it passes back to the boiler. Fig. 1 shows an example of a shell and tube type heat exchanger which would be fitted between the feed pump and boiler. Fig. 2 shows an example of three HP heaters connected in series.
