Abstract: While present energy needs can be met with available supplies of fossil fuels, the need to plan for the eventual elimination of dependence on premium fuels in utility and industrial applications remains urgent. Along with continuing awareness of the need for non-petroleum-based power and heat production is the renewed interest in cogeneration systems, for reasons of both energy conservation and the economies possible in meeting industrial/commercial process and space heat needs. One of the most promising power conversion technologies for these needs is the closed cycle gas turbine (CCGT) configured for power and heat production. The CCGT offers the ability to operate with a wide range of fuel types and qualities and to provide congenerated heat and power over a wide range of power-to-heat ratios. Additionally, the CCGT has the unique advantage of operating over a wide capacity range at no significant compromise in efficiency. Closed cycle gas turbines have been in commercial use, principally in Europe, for over four decades. That experience base, combined with emerging awareness of potential CCGT applications, could lead to the operation of coal-fired CCGT cogeneration systems in the U.S. within the next decade. This paper discusses the multi-fuel capability of the CCGT and compares its performance as a flexible cogeneration system with that of a more conventional steam turbine system.
