Also, the HRSG division manufactures and distributes HRSGs (Heat Recovery Steam Generator
) to combined-cycle power plants at home and abroad.
The standby steam and power concerns were addressed by the installation of a 200 psig (1379 kPa) natural gas turbine-generator combined heat and power (CHP) unit to increase overall thermal efficiency and produce steam via a combination heat recovery steam generator
and natural gas-fired duct burner of standby power at 4,160 V via a natural gas-turbine generator.
The combined cycle plant's main components are a gas turbine, a steam turbine, a heat recovery steam generator
and two generators.
It will be used in conjunction with a heat recovery steam generator
(HRSG) and SCR system built by Rentech Boiler Systems in Abilene, Texas for installation on a gas fired turbine at the Rand Whitney Paper Mill, Connecticut.
In repowering the plant, the original boiler was replaced with a heat recovery steam generator
and a combustion turbine that can bum natural gas and fuel oil.
GE also provided accessories and auxiliary systems, Mark V control panels, three heat recovery steam generator
boilers and three air coolers for cooling process gas.
AT A fuel price of $6 per million British thermal units (MMBtu), solar steam generators produce the lowest cost steam at $17 per tonne of steam, compared to $20 per tonne from cogeneration using a fully burdened once-through heat recovery steam generator
(OT-HRSG) and $27 per tonne for an environmentally burdened gas-fired once-through steam generators (OTSG).
A typical industrial CHP application for gas turbines is a chemicals plant with a 25 MW simple cycle gas turbine supplying base-load power to the plant with an unfired heat recovery steam generator
(HRSG) on the exhaust.
Under the terms of the contract, Alstom will supply a fully integrated turnkey power plant, which will comprise one combined-cycle unit, oneagas turbine, one heat recovery steam generator
, one steam turbine, one turbogenerator and a distributed control system.a Ghannouch will be the third power plant constructed by Alstom for STEG in Tunisia, after the combined-cycle power plants of Sousse and Rades, which went online in 1994 and 2001 respectively.
Hoping to diversify the country's hydro-power dominated energy mix, the EIB wants to help Latvenergo replace an existing CHP plant with a modern gas-fired combined cycle unit, heat recovery steam generator
and steam turbine.
