| Description |
The purpose of turbine technology is to extract the maximum quantity of energy from the working fluid, to convert it into useful work with maximum efficiency, by means of a plant having maximum reliability, minimum cost, minimum supervision and minimum starting time. It has been found that a newlineconsiderable amount of heat energy goes as a waste with the exhaust of the gas newlineturbine. This energy must be utilized. The complete use of the energy available to a newlinesystem is called Total Energy Approach. The objective of this approach is to use all newlineof the heat energy in a power system at the different temperature levels at which it newlinebecomes available to produce work, or steam, or the heating of air or water, thereby newlinerejecting a minimum of energy waste. Development of mixed cycle is the efficient newlineand effective effort in this direction. The concept and development of mixed cycle originated from the utilization of waste heat of thermal power plant. The heat rejected by gas turbine is highly appreciable as the exhaust temperature varies from 450oC to 650oC depending upon pressure ratio and turbine inlet temperature. This energy goes as a waste if it is rejected to atmosphere. This waste heat energy may be utilized to produce steam in a heat recovery steam generator (HRSG). The steam generated in HRSG may be expanded in steam turbine to newlinedevelop additional power based on Rankine cycle. This combination may term as newlinegas/steam combined cycle power plant. The gas cycle (Topping cycle) and steam newlinecycle (Bottoming cycle) may use separate generator or a single generator. It is newlinedesirable that the exhaust temperature of gas turbine should be above 570oC otherwise the steam cycle will be inefficient resulting in lower combined cycle efficiency.
