Combined Cycle Power Plant Ccpp
1. High efficiency:
The efficiency can be up to 60%.
2. Environmental compatibility:
Modern combustion engineering also means that the emission of exhaust gases can be controlled and minimized. Compared with all other conventional thermal plants, such as coal-fired power plants, carbon dioxide and nitric oxide emissions are very low when plants are fired with natural gas.
3. Low installation cost
Combined cycle equipment is pre-engineered and factory-packaged to minimize installation time and cost.
4. Fuel Flexibility
Combined-cycle plants operate efficiently by burning a wide range of fuels ,ranging from clean natural gas and distillate oil fuels to ash bearing crude oil and residual oil fuels. Operation with coal-derived gas fuels has been applied in many commercial-size combined-cycle systems.
5. Rapid start-up
Its operational flexibility allows rapid start-up, minimal shut-down times and fast and efficient adjustment to varying load demands
6. Short construction period
The very powerful gas tur
bine allows for a compact power plant, which minimizes the construction time to around just two-and-a-half years.
7. Less staff and space requirement
Gas-fired combined-cycle power plants are often built on a modular basis, being composed of several different units. Each unit is practically a self-contained power plant that can be operated indepemdently of the others, which requires comparatively fewer staff.
