Integrated Gasification Combined Cycle (IGCC) An Integrated Gasification Combined Cycle ( IGCC) is a technology that aims to extract the maximum energy out of a fuel that is burnt. In the case of coal, the carbon conversion efficiency in an IGCC plant is higher than that in a conventional pulverised coal (PC) fired power plant.
The project centered on the elimination of a coal boiler at the Wade Power Plant and the installation of a gas turbine combined heat and power system. Project includes the demolition of Boiler 1, a 215,000 lb/hr coal-fired stoker boiler and the conversion of Boiler 2, also a 215,000 lb/hr unit, from coal to natural gas.

Boiler Combined-Cycle Power Plant OVERVIEW: To improve the thermal efficiency and environmental characteristics of coal-fired power-generation systems, The Chugoku Electric Power Co., Inc. and the Hitachi Group developed the first commercial 250-MW PFBC (pressurized fluidized bed combustion) combined-cycle power plant in Osaki.
Typical thermal efficiency for utility-scale electrical generators is around 37% for coal and oil-fired plants, and 56 – 60% (LEV) for combined-cycle gas-fired plants. Plants designed to achieve peak efficiency while operating at capacity will be less efficient when operating off-design (i.e. temperatures too low.)
The thermal stress caused by load cycling of coal-fired and combined-cycle plants increases operating & maintenance costs according to a National Renewable Energy Laboratory (NREL) study, Power Plant Cycling Costs. For North American power producers, the aging workforce is another challenge.
CO 2 emissions from power plants using combined cycle technology are about 50 percent lower than most coal-fired plants. Emissions of NOx and SO 2 are 80 to 90 percent lower.

Combined cycle plant for power generation is a plant that converting the energy in natural gas/fuel into electrical power involves the creation of mechanical work which is then transformed into electric power by a generator. The term “combined cycle” referred to the multiple combination of thermodynamics cycle to generate electricity.
The thermal efficiency of today’s combined-cycle power plants are much higher than conventional steam power plants. For example, a combined-cycle power plant with the F-class gas turbine having firing temperatures between 1300 and 1400°C attains thermal efficiency of 55–57%.
As coal-fired power plants gradually become less sustainable, combined-cycle power plants offer an alternative for domestic power generation that is both cleaner and more efficient. Advances in hydraulic fracturing technology and the resulting shale gas boom have made natural gas the fuel of choice for an increasing number of private investors and consumers.
EUROWATER has supplied water treatment plant for one of Poland's largest Combined Cycle Gas Turbines with a generation capacity of 400 MVe and 240 MWt, located in the town of Stalowa Wola. This project is one of the first state-of-the art large CCGT gas fired power projects in Poland and part of Poland's drive to reduce reliance on use of coal for power generation.
Combined cycle power plants integrate two thermal cycles, operating at a high- and low-temperature range, respectively, to yield higher plant efficiency and output than either cycle operating alone. Each cycle operates with separate working fluids and the two cycles are integrated by exchange of heat from the high-temperature (topping) cycle to the lower temperature (bottoming cycle).

Basic combined cycle. One is the Joule or Brayton cycle which is a gas turbine cycle and the other is Rankine cycle which is a steam turbine cycle. The cycle 1-2-3-4-1 which is the gas turbine power plant cycle is the topping cycle. It depicts the heat and work transfer process taking place in high temperature region.
In fossil and combined cycle plants, high-energy piping (HEP) systems, including main steam, hot reheat, cold reheat, and feedwater piping, are critical in terms of personnel safety and overall plant longevity.
son, a typical natural gas combined cycle power plant will have emissions of 800-900 lbs/MWh, and a coal plant will have CO 2 emissions near 2,000 lbs/MWh.

Integrated gasification combined cycle (IGCC) plants use a two-step process to create electricity. In the first step, coal is converted into synthetic gas or syngas . In the second step, the gas is used to power a steam turbine, with waste heat from the turbine being recovered to provide additional power (hence the term "combined cycle").
