Influence of climatic parameters on optimal design of supercritical power plants

Environmental controls and increasing dependence on fossil fuel fired plants have resulted in an on-going worldwide effort for optimal design of thermal power plant cycles. An effective measure to improve heat rates of steam power plants has been the use of steam at supercritical pressures and elevated temperatures. A considerable body of literature and on-site experience exits for the optimal design of such systems. Although such plants have been in use in developed countries, their use is being considered only now for developing countries such as India, where climatic conditions are vastly different. The ambient and cooling temperatures influence the selection of critical optimal parameters such as reheat pressures, thus affecting the cycle heat rate and net work output of the cycle
