2015/3/17 · Steam, Boiler, and Blowdown Pressure are the same. Combustion Efficiency is the % of fuel energy that is directly added to the feedwater and not otherwise lost or used. Blowdown Rate is the % of incoming feedwater mass flow rate that leaves the boiler as a saturated liquid at boiler pressure.
Boiler Feed Pump - an overview | ScienceDirect Topics
1.4 Boiler Feed Pumps. The outlet of a deaerator is connected to the boiler feed pump (BFP) suction and from there to the popular term of the working fluid—feedwater—to reach the boiler proper. It impels the FW with requisite pressure that dictates the working or operating point of steam generation.
