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 diagram of IGCC (integrated gasification combined cycle) power plant. TPD = tons per day, psi (unit of pressure) = pound-force per square inch. The diagram is based on: Jeff Crook, Back to the future, IET Power Engineer, June/July 2006, pp. 26-29 .
A process flow diagram (PFD) is a diagram commonly used in chemical and process engineering to indicate the general flow of plant processes and equipment. The PFD displays the relationship between major equipment of a plant facility and does not show minor details such as piping details and designations.
The basic operation of the gas turbine is a Brayton cycle with air as the working fluid: atmospheric air flows through the compressor that brings it to higher pressure; energy is then added by spraying fuel into the air and igniting it so that the combustion generates a high-temperature flow; this high-temperature pressurized gas enters a ...
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.
The software is used by plant developers (e.g. EPC) to plan process plants (chemical, energy, water / waste water, pharmaceuticals, oil, natural gas, food, etc.). It is also used by plant owner/operators in the mentioned industries, since COMOS not only supports engineering but also operational processes. There are regular user conferences.

A key issue in implementing IGCC is its high capital cost, which prevents it from competing with other power plant technologies. Currently, ordinary pulverized coal plants are the lowest cost power plant option. The advantage of IGCC comes from the ease of retrofitting existing power plants that could offset the high capital cost. In a 2007 ...
