Boiler (power generation) - Wikipedia

22/1/2019 · A steam boiler is a power generation device, used for generating steam by applying the heat energy to water. The pressure range of earlier boilers ranges from low pressure to medium pressure (7 kPa to 2000 kPa/ 1psi to 290 psi). The present boilers are more useful because it works with high pressure than old ones.

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.

28/9/2016 · If you have a boiler set at 7 psi, the steam temperature is about 232 ° F. Steam traps will open once the steam temperature drops 10 ° to 20 °. The discharge temperature of the trap will be between 212 ° and 222 ° into a pipe at atmospheric pressure. At those temperatures, the water flashes to steam.

Steam Boiler Pressure

In steam boiler technology, it is routine for all pressures to be stated as excess pressure relative to an atmospheric pressure of 1 bar. The unit [bar] or [barg] is used at these points. The excess pressure is therefore converted to absolute pressure as follows: Conversion from excess pressure to absolute pressure

17/3/2015 · 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.
