Analyze of gas turbine performances with the presence of the steam water in the combustion chamber

The role of gas turbine m the nuclear and conventional power industries has received considerable attention over the past several decades. However, in order to improve the performances of gas turbine, different methods such as regeneration, intercooler intermediate, pre-heating and injection of the steam water have been used. This later method is the more beneficial to increase efficiency. The steam water injection at the upstream of the combustion chamber has been proposed. The main purpose of the present work is to analysis the effect of the environmental conditions on the thermodynamic cycle processes of gas turbine, by using analytical relations. The quantity of water vapor carry' through will be injected only when the ambient conditions become higher than standards. The influence of inlet temperature and pressure, ambient temperature and the combustion comber temperature over a wide operating range are evaluated. Design data of an industrial gas turbine are employed to show the variation of injected steam water. The results obtained of infection are in good agreement with the qualitative variation of these, conditions in the case of normal operation without infection of the steam. For better illustration of the physical phenomena, the results are represented in the form of curves into both two and three dimensions.
