The combined power plant has importance features is its relatively low capital investment and environment advantages compared with the conventional power plant. The conventional power plants have lower efficiencies. Now a days for the new integration improvement system is the combined cycle power plant. In current situation the combined cycle power plant is new technology and its offers optimum efficiency to any of the gas turbine power plant. In this paper comparing four different cycles to analysis optimization of waste heat Recovery: i. Gas turbine, ii. Reheat steam turbine, iii. Steam turbine without Reheat, iv. Steam turbine power plant. The new integration system combined cycle plant would produce 100 MW of power (67 MW from the gas turbine and 33 MW from the steam turbine). The gas turbine cycle is more effective using the combined cycle power plant and its higher efficiency. The initial way to adopted is the four cycle of the possible of the combined power plant. Now, the selection of gas turbine cycle, the next step is to analysis the impact of the steam cycle design and parameters on the general performance of the plant. Each alterative cycle was analysed, getting to find the simplest possible option from the standpoint of overall efficiency, installation and operational costs, maintainability and reliability for a combined power station. There are several schemes are proposed for investigation. During this paper to seek out the overcome of the restrictions of the traditional analyses and to extend our knowledge a few plant, advance Heat Recovery Steam generator with low emission exergy have been developed. Resulting in the Gas turbine output is 67.8 MW, steam turbine output is 34.8 MW. Steam cycle efficiency is 22.5% and the overall efficiency is 53.2%. Net power output of plant 101.4 MW. Utilization rate of waste heat energy 62.4%. The results indicated that the utmost exergy loss within the turbine cycle occurs within the combustion chamber thanks to its high irreversibility because the second major exergy loss is in HRSG, the optimization of HRSG has a crucial role in reducing the exergy loss of combined cycle.
