  • Boiler Efficiency and Steam Quality: The Challenge of

    When a steam valve opens, two problems occur in the boiler. First, steam pressure drops rapidly. The drop in steam pressure itself causes additional entrainment as explained in Case II above. Second, the interface between water and steam rises.

  • Is superheated steam pressure and temperature the same as

    Answer (1 of 5): No it isn't. Superheated steam cannot exist in a boiler drum, it can only exist in a moving fluid. This is why the superheater tubes are separate from the rest of the boiler tubes, where the steam has to be moving to have heat imparted to it. If there is no movement, the superhea

  • Steam Boiler - Definition, Working Principle, Types, and

    What is a Steam Boiler? 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 …

  • Steam Calculators: Boiler Calculator

    Mar 17, 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.
