Single pressure HRSGs have only one steam drum and steam is generated at a single pressure level, whereas multi pressure HRSGs employ two (double pressure) or three (triple pressure) steam drums. As such, triple pressure HRSGs consist of three sections: an LP (low pressure) section, a reheat/IP (intermediate pressure) section, and an HP (high ...
By 1905, when steam turbines were coming into use on fast ships (such as HMS Dreadnought) and in land-based power applications, it had been determined that it was desirable to use one or more Curtis wheels at the beginning of a multi-stage turbine (where the steam pressure is highest), followed by reaction stages.
It will supply a new low-pressure turbine, complete inner part of the high-pressure turbine, valves, generator and spare parts as required. [6] At Finland's Hanasaari heating plant, Doosan Škoda Power is currently modernising the existing Škoda back-pressure steam turbine, adding 3D blading rotors and new diaphragms, inner casings and turning ...
It has two water/steam drums. The low-pressure drum is connected to the low-pressure economizer or evaporator. The low-pressure steam is generated in the low temperature zone of the turbine exhaust gasses. The low-pressure steam is supplied to the low-temperature turbine. A super heater can be provided in the low-pressure circuit.
Monotube steam generator: A single tube, usually in a multi-layer spiral, that forms a once-through steam generator. The first of these was the Herreshoff steam generator of 1873. [38] Multi-tube boiler: fire-tube boiler with multiple small fire-tubes, rather than a single large flue.
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.
A 60 kW generator set fueled by waste motor oil [44] Chuk Williams' steam-powered land speed record car, [6] [45] followed by a land speed record car built by Cyclone Power Technologies [46] A speed boat designed to break the steam-powered water speed record. [12] A multi-fuel engine to provide hydraulic power to forklift trucks [47]
Steam generator (auxiliary boiler), a steam-powered boiler used on ships to produce a low-pressure steam, heated by a high-pressure steam supply rather than a flame. Steam generator (boiler), an oil- or gas-fired boiler, based on a low-water content monotube coil. Steam generator (nuclear power), a heat exchanger in a pressurized water nuclear ...
