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 pressure is the key factor for determining the need for a condensate polishing system. With a steam generator plant with low steam pressures (below 40 kg/cm2 ), the requirement of the CPU is usually avoided. Hard scale formation and boiler metal corrosion can easily be prevented through FW treatment before sending to the boiler proper.
