Read MoreA closed pressure vessel known as Steam generator or Boiler is used to generate steam at desired pressure and temperature by transferring heat to water contained in a closed pressure vessel. Before we go in details of the boiler it is necessary to know few terms used in boiler.

Read More2015/3/17 · 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.
