Evaluation of the Impact of High Exhaust Temperature in Steam Turbine Operation

Steam turbine which operates due to dynamic action of the steam has a very high exhaust temperature. This work is done on the evaluation of high exhaust temperature in steam turbine operation. Optimizing process operating conditions can considerably improve the turbine water rate, which in turn will significantly reduce energy requirement. This work is further designed for particular operating conditions like steam inlet temperature and turbine exhaust pressure/exhaust vacuum, steam inlet pressure, which affects the performance of the turbines in a significant way. Variations in these parameters affect the steam consumption in the turbines and also the turbine efficiency. Improving the power output of the turbine, thermal efficiency and specific steam consumption in conventional steam power plants is inclusive. Four cycles, i.e; rankine cycle, regenerative cycle, superheat cycle and cogeneration cycle are considered to formulate the data and obtain a better result in steam turbine power.
