| Abstract | ||
| Abstract The exhaust gases of gas turbines carry a significant amount of thermal energy that is usually expelled to the atmosphere without taking any further part in the power generation process. This low grade thermal energy can however be put into beneficial use as a heat source to a vapor absorption chiller that serves as cooling system to be operated during hot months to cool inlet air to the gas turbine to raise its power generation design level. This paper describes the thermal and economic advantages of using a Single Stage LiBr-H2O absorption chiller to boost the power output of a gas turbine generator with application to Mosul gas turbine power plant. The results showed that maximum increase in power output when inlet cooling involved is approximately 17.5%, which occurs in July and August being the hottest month in the year. The economic results showed that maximum economic saving of $34.9 million dollar which represent 8% saving can be obtained at inflation rate of 6% and interest rate of 1%.
