A gas-fired power plant, sometimes referred to as gas-fired power station, natural gas power plant, or methane gas power plant, is a thermal power station that burns natural gas to generate electricity. Gas-fired power plants generate almost a quarter of world electricity and are significant sources of greenhouse gas emissions. [1]
A combined cycle power plant is an assembly of heat engines that work in tandem from the same source of heat, converting it into mechanical energy. On land, when used to make electricity the most common type is called a combined cycle gas turbine (CCGT) plant, which is a kind of gas-fired power plant.
A gas turbine or gas turbine engine is a type of continuous flow internal combustion engine. [1] The main parts common to all gas turbine engines form the power-producing part (known as the gas generator or core) and are, in the direction of flow: a rotating gas compressor; a combustor; a compressor-driving turbine.
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.
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 ...
It had a CCGT-type power station that runs on natural gas. It had one General Electric 50Hz H-class system [5] (9H) gas turbine which achieves a firing temperature well above 2,600F linked on a single-shaft to a heat recovery steam generator and a GE steam turbine. It had black start capability, using a 33MWe
The Medway Power Station, a combined-cycle gas turbine (CCGT) power station in Kent, UK, with two gas turbines and one steam turbine, is rated 700 megawatts. [28] The rated capacity of a power station is nearly the maximum electrical power that the power station can produce.
In this example the syngas produced is used as fuel in a gas turbine which produces electrical power. In a normal combined cycle, so-called "waste heat" from the gas turbine exhaust is used in a Heat Recovery Steam Generator (HRSG) to make steam for the steam turbine cycle. An IGCC plant improves the overall process efficiency by adding the ...
