This article gives a general information about the Combined Cycle Power Plants which is an energy production system allowing to produce Steam, Heat and Electricity together in an energy efficient way. Combined cycle is the alternative power generating system which provides maximum efficiency and minimum impact on the environment. Off all processes available today for power generating in industry and utilities, there is no doubt that the combined cycle system offers the best prospects for the future. [1-27]
Combined cycle system has great development potential in the fields of technology and application and features above all; environmental compatibility, greater fuel efficiency, lower investment costs with a faster rate of amortisation. The present state of gas turbine technology featuring a wide range of outputs allows for a great variety of applications in many different fields. These include; smaller in-plant power supply units for factories needing process heat for production, industrial power plants, utilities for district heating. Here, of course we are referring not only to building new power or heat facilities but also to upgrading or retrofitting existing ones. [1-27]
