Drum Type and Once Through Boiler Design

A closer regime of operation is expected in once through boilers. The absence of the drum makes it possible to reduce the overall cycle time for the once through boiler. However, the overall plant cycle time may not vary only marginally. Once through boilers life …

Boiler (power generation) - Wikipedia

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.

ONCE-THROUGH BOILERS

Once-through boilers are generally associated with high pressure operation and the feed water enters at high sub-critical (>180 bar) or supercritical pressure whilst superheated steam leaves at a pressure some 20–30 bar lower. Sliding pressure operation is adopted to accommodate requirements of …

Once-Through Boilers | Boilers - Product Lineup

Once-through boilers are able to produce steam at higher pressures and temperatures than drum boilers. In thermal power plants, raising steam conditions (pressure and temperature) can enable efficiency gains in power generation equipment, allowing an operator to reduce its fuel consumption and CO 2 emissions. Mitsubishi Hitachi Power Systems (MHPS) delivered its first supercritical pressure
