  • Steam Pressure Reduction: Opportunities and Issues

    Steam Pressure Reduction: Opportunities and Issues varies directly in proportion to the boiler's net stack temperature (the difference between the flue gas tem- Using the ABMA standard radiation loss chart, this would yield a savings of 0.2% of the fuel input.Learn More

  • 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.Learn More

  • Boiler – Fundamentals and Best Practices

    Steam Production At normal atmospheric pressure, any further addition of heat to water at 100°C will not increase the temperature but will convert some of the water into steam In order to convert water into steam 2,257 kJ/kg (971Btu/lb) of additional heat must be added This cannot be detected as a rise in temperature and is called the LatentLearn More

  • Boiler (power generation) - Wikipedia

    Supercritical steam generators are frequently used for the production of electric power. They operate at supercritical pressure. In contrast to a "subcritical boiler", a supercritical steam generator operates at such a high pressure (over 3,200 psi or 22.06 MPa) that actual boiling ceases to occur, the boiler has no liquid water - steam separation.Learn More

  • Calculate How To

    Oct 28, 2018 · Instant steam production means that the production of steam begins a few minutes, generally 2-3, after the ignition of the burner. In water tube steam generators, water flows into the tube bundles with a high exchange surface and is heated by the combustion gas; smoke tube boilers instead have water surrounding the tubes.Learn More

  • Boiler Project Fundamentals - AIChE

    Heat-recovery steam generator A heat-recovery steam generator (HRSG) is a type of heat exchanger that recovers heat from a hot gas stream and produces steam (Figure 1). The steam can be used in a process or used to drive a steam turbine for electricity production. You might choose an …Learn More
