This paper examines various cogeneration alternatives available today and provides an economic comparison for a range of conditions that will enable the most significant factors to be considered in the selection of cogeneration alternatives, and to determine which alternatives are most suitable for the particular application. The cogeneration methods considered are: a combustion turbine electric generating unit followed by an unfired heat recovery steam generator, a combustion turbine electric generating unit followed by a supplementary fired heat recovery steam generator, a combustion turbine electric generating unit followed by a fully fired boiler, a combined-cycle combustion turbine electric generating unit followed by a supplementary fired high-pressure heat recovery boiler delivering steam to a noncondensing steam turbine-generator, a combined-cycle combustion turbine electric generating unit followed by a fully fired boiler delivering steam to a noncondensing steam turbine-generator, and a conventional coal-fired boiler and a noncondensing steam turbine-generator. It is concluded that over a wide range of financial and operating conditions, almost all of the cogeneration/combined-cycle alternatives are more economical than continued operation of an existing conventional boiler generating steam only.
