Abstract
It is known that the efficiency of gas turbines is low, especially when operating in harsh conditions such as high air temperature. Therefore, the performance of gas turbines has been improved by intercooling and heat regenerative. In this work, the possibility of improving efficiency and production capacity was studied by injecting steam into the combustion chamber of a gas turbine, in the presence of intercooling and heat regenerative, the cooling process is carried out by pumping water to cool the compressor, so that it turns into steam, which is then injected into the combustion chamber after passing through a heat recovery steam generator HRSG. The focus has been on the study of the change in the ratio of water to air, as well as the amount of intercooling. The results showed that there is a possibility to raise the efficiency and production capacity at a high water-air ratio, the temperature of the combustion gases has decreased, which helps the turbine blades to withstand, and the production of nitrogen oxides polluting the environment has decreased.
