The German Navy launched the first Köln-class frigate in 1961 with 2 Brown, Boveri & Cie gas turbines in the world's first combined diesel and gas propulsion system. The Soviet Navy commissioned in 1962 the first of 25 Kashin-class destroyer with 4 gas turbines in combined gas and gas propulsion system. Those vessels used 4 M8E gas turbines ...
The original Ruston works (Waterside South, Lincoln) focused on Gas Turbine manufacture from 1967 becoming the head office of Ruston Gas Turbines. Napier Turbochargers, that had been owned by English Electric since 1942, moved to the site from Liverpool. With the change of ownership in 1989 the name was changed to European Gas Turbines Ltd.
Dry low emission (abbreviation DLE) is a technology that reduces NOx emissions that exhausts out of gas fired turbines. [1] [2] [3] [4]The amount of NOx produced depends on the combustion temperature. [2]
Fuels such as natural gas or oil can also be burnt directly in gas turbines (internal combustion), skipping the steam generation step. These plants can be of the open cycle or the more efficient combined cycle type. The majority of the world's thermal power stations are driven by steam turbines, gas turbines, or a combination of the two.
It is a CCGT type power station running on natural gas. There are two General Electric Frame 9FA gas turbines each rated at 250 MWe. The total thermal input is 1329 MW. Each gas turbine is connected to a heat recovery steam generator which connect to one steam turbine which has an output of 260 MWe. Steam is condensed using water from the River ...
The steam so produced is injected into the gas turbine's combustion chamber to increase power output. [3] The process can be thought of as a parallel combination of the gas turbine Brayton cycle and a steam turbine Rankine cycle. [4] [5] The cycle was invented by Prof. Dah Yu Cheng of the University of Santa Clara who patented it in 1976. [6] [1]

A closed-cycle gas turbine is a turbine that uses a gas (e.g. air, nitrogen, helium, argon, [1] [2] etc.) for the working fluid as part of a closed thermodynamic ...
Initially, the first engines developed (GT-300 and 302) did not have a regenerator, but adding regeneration to recapture heat from the exhaust gases was found to reduce fuel consumption by 1 ⁄ 2 for the second-generation GT-304, so subsequent generations of GM Whirlfire gas turbine engines incorporated a regenerator.
