Feedwater Heaters: Not to Be Ignored | Engineering360
2016-5-17 · Feedwater Heaters: Not to Be Ignored Victor Rodgers | May 17, 2016 Power plant feedwater heaters (FWHs) make the most of the heat from condensation to preheat water destined for the boiler. In doing so, they reduce the amount of fuel required to bring the water up to temperature. Placement of high pressure and lower pressure heaters in
LG High Pressure Boiler Feed Water Pump
Boiler feedwater heaters are designed to improve boiler efficiency by extracting heat from streams such as boiler water blowdown and turbine extraction or excess exhaust steam. Feedwater heaters are generally classified as low-pressure (ahead of the deaerator), high-pressure (after the deaerator), or deaerating heaters.

Boiler Cycling Considerations – babcock.com
Feedwater flow is started when the initial load is applied to the turbine. Because little extraction heating is available, feedwater temperature is initially low. A thermal shock can occur as extractions are cut into feedwater heaters and the temperature can increase several hundred degrees F (C) in a few minutes.
Boiler Feedwater Heater – ProSonix
A ProSonix heater can be installed in boiler feedwater applications to heat up the returned condensate with low pressure steam from the turbine. Boiler Feedwater Heaters via Direct Steam Injection High Turndown on both steam and liquid allow for process flexibility and process condition variations.
Feedwater Heater Tubes, High Pressure & Boiler Feed
2019-7-8 · In steam power plant, feedwater heaters allows the feeadwater to be brought upto the saturation temperature very gradually. The purpose of feedwater heaters is they provide efficiency gains in the steam cycle by increasing the initial water temperature to the boiler, so there is less sensible heat addition which must occur in the boiler.
