    Boiler (power generation) - Wikipedia

    2019-5-4 · A boiler or steam generator is a device used to create steam by applying heat energy to water.Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (7–2,000 kPa or 1–290 psi) but, at pressures above this, it is more usual to speak of a steam generator.

    2019-5-16 · Heating accounts for about 55 per cent of what you spend in a year on energy bills, so an efficient boiler makes a big difference. All well-maintained boilers burn their fuel very efficiently, but they inevitably lose some heat in the hot gases that escape up the flue (a pipe for extracting fumes and supplying fresh air to the boiler).

    2003-10-30 · In once-through boilers the determination of specific enthalpy after the evaporator is based on the temperature. The reason for this is the unclear state of supercritical steam after the evaporator in once-through circulation. The temperature after the evaporator in once-through boilers is typically between 400 and 450 °C. 4.
