There are two types of air preheaters for use in steam generators in thermal power stations: One is a tubular type built into the boiler flue gas ducting, and the other is a regenerative air preheater. [1] [2] [7] These may be arranged so the gas flows horizontally or vertically across the axis of rotation.
The Cyclone Mark V Engine is a steam engine in which the engine, steam generator, condenser and feed pump are integrated into a single compact unit. The company Cyclone Power Technologies of Pompano Beach, Florida was founded by inventor Harry Schoell to develop and market this engine.
A heat recovery steam generator (HRSG) is an energy recovery heat exchanger that recovers heat from a hot gas stream, such as a combustion turbine or other waste gas stream. It produces steam that can be used in a process ( cogeneration ) or used to drive a steam turbine ( combined cycle ).
The Primary air fan takes air from the atmosphere and, first warms the air in the air preheater for better economy. Primary air then passes through the coal pulverizers, and carries the coal dust to the burners for injection into the furnace. The Secondary air fan takes air from the atmosphere and, first warms the air in the air preheater for ...
[48] [49] In 2014, Alstom sold its steam auxiliary components activities (air preheaters and gas-gas heaters for thermal power, other industrial heat transfer equipment, and grinding mills) to Triton Partners for €730 million. [50] In November 2014 Alstom was awarded a $429.4 million contract to modernise 85 trains for the Mexico City Metro ...
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.

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 ...
