Test results of a steam injected gas turbine to increase power and thermal efficiency
The desire to increase both power and thermal efficiency of the gas turbine (Brayton cycle) engine has been pursued for a number of years and has involved many approaches. The use of steam in the cycle to improve performance has been proposed by various investigators. This was most recently proposed by International Power Technology, Inc. (IPT) and has been tested by Detroit Diesel Allison (DDA), Division of General Motors. This approach, identified as the Cheng dual-fluid cycle (Cheng/DFC), includes the generation of steam using heat from the exhaust, and injecting this steam into the engine combustion chamber. Test results on an Allison 501-KB engine have demonstrated that use of this concept will increase the thermal efficiency of the engine by 30% and the output power by 60% with no increase in turbine inlet temperature. These results will be discussed, as will the impact of steam rate, location of steam injection, turbine temperature, and engine operational characteristics on the performance of the Cheng/DFC.
