“…Rice [2] developed a steam injected gas turbine cycle with a topping in which a HP steam is first expanded in a back-pressure steam turbine, producing power, and then is injected into the combustion chamber of the gas turbine. Borat [3] found that the efficiency and the net output of the gas turbine increased considerably, of the order of 20-40 percent with the steam injection. Poullikkas [4] reviewed the gas turbine technologies and emphasized on various advance cycles involving heat recovery from the gas turbine exhaust, such as, the gas to gas recuperation cycle, the combined cycle, the chemical recuperation cycle, the Cheng cycle, the humid air turbine cycle, etc.…”

A gas turbine performance prediction tool has been implemented using a simulation software package to accurately predict the performance of SGT5-4000F heavy-duty gas turbines.Comparing the results obtained from this simulation with data collected from the field, a significant agreement between them is found within an acceptable tolerance of about 4%. The model has been built to work at both steady state and transient combining the control protocols, thus achieving the maximum allowable output power with various operating parameters.This study aims to use the implemented model to investigate the effect of Steam Injection Gas Turbine cycle (STIG) as well as the change in ambient temperature on the performance of the unit in terms of both output power and efficiency. The results indicate a significant improvement in performance using this specific technology.

“…Rice studied about a steam injected gas turbine cycle with a topping in which a high pressure (HP) steam is first expanded in a back‐pressure steam turbine, producing power, and then is injected into the combustion chamber of the gas turbine. Borat found that the efficiency and the net output of the gas turbine increased considerably, of the order of 20–40% with the steam injection. Poullikkas reviewed the gas turbine technologies and emphasized on various advanced cycles involving heat recovery from the gas turbine exhaust, such as, gas to gas recuperation cycle, CC, chemical recuperation cycle, Cheng cycle, humid air turbine cycle, etc.…”

SUMMARYThe attractive features of a combined cycle (CC) power plant are fuel flexibility, operational flexibility, higher efficiency and low emissions. The performance of five gas turbine‐steam turbine (GT‐ST) combined cycle power plants (four natural gas based plants and one biomass based plant) have been studied and the degree of augmentation has been compared. They are (i) combined cycle with natural gas (CC‐NG), (ii) combined cycle with water injection (CC‐WI), (iii) combined cycle with steam injection (CC‐SI), (iv) combined cycle with supplementary firing (CC‐SF) and (v) combined cycle with biomass gasification (CC‐BM). The plant performance and CO2 emissions are compared with a change in compressor pressure ratio and gas turbine inlet temperature (GTIT). The optimum pressure ratio for compressor is selected from maximum efficiency condition. The specific power, thermal efficiency and CO2 emissions of augmented power plants are compared with the CC‐NG power plant at the individual optimized pressure ratios in place of a common pressure ratio. The results show that the optimum pressure ratio is increased with water injection, steam injection, supplementary firing and biomass gasification. The specific power is increased in all the plants with a loss in thermal efficiency and rise in CO2 emissions compared to CC‐NG plant. Copyright © 2013 John Wiley & Sons, Ltd.
