A combined cycle power plant has a number of gas turbines each feeding exhaust gas to an associated heat recovery steam generator to generate steam which is supplied to a common header. Provision can also be made for supplementary firing of the heat recovery steam generator to produce additional steam flow. The combined cycle plant also has a steam turbine with a special control system to
The whole power plant then uses less than 10% of the water required for a wet-cooled plant j, but some power (around 1-1.5% of the power station's output) is consumed by the large fans required. k This is direct dry cooling, using air-cooled condenser (ACC) and the only nuclear power plant where it is in routine use is for the very small

A combined combustion and steam turbine power plant which includes a steam turbine unit, a boiler unit for supplying steam to the steam turbine unit, and a combustion turbine unit with an exhaust gas duct structure for supplying the turbine exhaust gases to the boiler unit, has at least one heat recovery steam generator arranged in the exhaust gas flow downstream of the boiler unit and
2021-3-18 · 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.The same principle is also used for marine propulsion, where it is called a combined gas and steam (COGAS) plant.
2020-6-26 · It is also possible to use the steam from the boiler for heating purposes so such power plants can operate to deliver electricity alone or in combined heat and power (CHP) mode.. Mechanism. Combined cycle power plant as in name suggests, it combines existing gas and steam technologies into one unit, yielding significant improvements in thermal efficiency over conventional steam plant.
Steam boiler efficiencies range from 70 to 85 % HHV depending on boiler type and age, fuel, duty cycle, application, and steam conditions. 4.5.5 Process Steam and Performance Tradeoffs Heat recovery methods from a steam turbine use back pressure exhaust or extraction steam.
2019-12-12 · In an oxy-combustion pulverized-coal-fired power plant (PC), a high CO2 content flue gas could be obtained, and this allows CO2 sequestration in an efficient and energy-saving way. To better understand the thermodynamic characteristics of the oxy-combustion process, a detailed exergy analysis of a 600 MWe oxy-combustion PC was carried out. The whole oxy-combustion PC system was
