In a simple cycle gas-turbine, also known as open-cycle gas-turbine (OCGT) generators, hot gas drives a gas turbine to generate electricity. This type of plant is relatively cheap to build and can start very quickly, but due to its lower efficiency is at most only run for a few hours a day as a peaking power plant. [8]
The gas-generator cycle, also called open cycle, is one of the most commonly used power cycles in bipropellant liquid rocket engines. Propellant is burned in a gas generator (or "preburner") and the resulting hot gas is used to power the propellant pumps before being exhausted overboard and lost.
A simple-cycle combustion turbine (SCCT) is a type of gas turbine typically used in the power generation, aviation , and oil and gas industries (for electricity generation and mechanical drives). The simple-cycle combustion turbine follows the Brayton Cycle and differs from a combined cycle operation in that it has only one power cycle (i.e. no ...
Didcot OCGT is an Open Cycle Gas Turbine that was originally part of Didcot A. Built in 1968, it uses four open-cycle gas turbines, which are each powered by a pair of Rolls-Royce Avon engines to generate 100MW of electricity. [50] The site was made separate from the Didcot A station as part of the decommissioning process. [51]
The LMS100 PA produces approximately 100 MW at an efficiency of around 46% LHV in open cycle operation. It is currently the largest and most efficient aero-derivative gas turbine. It is able to produce full rated power in under 10 minutes. [citation needed] The LMS100 comprises a low-pressure compressor, an intercooler, a supercore and a power ...
A similar diagram (ancestry unknown) appears on page 36 of IGCC 101 for Public Utilities Commission of Colorado / Steve Jenkins / URS Corporation / February 12, 2007. Context indicates that this applies to the Polk power station which started up July 1996. There are many other relevant diagrams in that PDF.
The plant consists of a single 270 MW conventional steam turbine and three 85 MW open-cycle gas turbines. The plant is fuelled with natural gas, which is supplied from the Bórd Gais network and diesel oil is used as an alternative fuel when natural gas supply is low. [5] [6]
