Cogeneration by Steam Injection to Gas-Turbine Engines
Maurer, Jack R.
Waste heat from the exhaust gas of a gas-turbine engine can be utilized to generate steam for industrial processing. The Cheng cycle has been proven to be economical in modifying existing engines and flexible in meeting a specific demand of power and steam variations. However, in designing such a power plant, many governing parameters need to be investigated for optimum operations. A computer program has been developed to analyze a combined Brayton gas-cycle and Rankine steam-cycle for variable-load users of power and steam cogeneration. The objective is to make maximum use of available energy with minimum impact on environment. The program was verified using available laboratory data for 100% power delivery. The amount of cogenerated steam and the thermal efficiency of the energy system were calculated as a function of compressor pressure ratio and turbine inlet temperature when the percentage of power reduction is specified.
