Boiler Feed Pump - an overview | ScienceDirect Topics

For recirculation flow of a BFP (the pump has its suction from the deaerator), the pump entire/partial flow water from the BFP is returned to the deaerator during startup and at low load. Generally, the BFP handles the high flow at high differential pressure (DP); the pump sizes are large so even for small units such recirculation flow is necessary.

Combustion of fuel release flue gases which is a mixture of Carbon Dioxide, Carbon Monoxide, Sulfur Dioxide, H 2 O Vapor, Nitrogen or Nitro-Oxides, Oxygen and ash particles. The quantity of flue gases is also calculated using stoichiometry calculation when air reacts with the fuel. You can also refer to Thermodyne's Boiler Bible that provides you the general composition of above elements for various …
