2. Air preheater - Wikipedia

   en.wikipedia.org/wiki/Air_preheater

   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.

3. Heat recovery steam generator - Wikipedia

   en.wikipedia.org/wiki/Heat_recovery_steam_generator

   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 ).

4. Boiler (power generation) - Wikipedia

   en.wikipedia.org/wiki/Boiler_(power_generation)

   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.

5. Combustion Engineering - Wikipedia

   en.wikipedia.org/wiki/Combustion_Engineering

   Combustion Engineering (C-E) was a multi-national American-based engineering firm that developed nuclear steam supply power systems in the United States.Originally headquartered in New York City, C-E moved its corporate offices to Stamford, Connecticut, in 1973.

6. Thermal power station - Wikipedia

   en.wikipedia.org/wiki/Thermal_power_station

   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 ...

8. Feedwater heater - Wikipedia

   en.wikipedia.org/wiki/Feedwater_heater

   A Rankine cycle with two steam turbines and a single open feedwater heater. A feedwater heater is a power plant component used to pre-heat water delivered to a steam generating boiler. [1] [2] [3] Preheating the feedwater reduces the irreversibilities involved in steam generation and therefore improves the thermodynamic efficiency of the system ...
