Advanced technology cogeneration system conceptual design study: closed cycle gas turbines
The importance of the study results to the industrial sector can best be illustrated by a review and contemplation of the Task III results. The objective of Task III was to apply what was learned about steam and closed-cycle gas turbine cogeneration systems during Tasks I and II, on a site specific basis, to the much broader industrial sector as a whole. The Task III data shows that the industrial sector can benefit, and can afford to benefit, from the use of coal-fired cogeneration systems provided: (a) The industrial site is located in a DOE region that is not predominately based on cheap hydroelectric or nuclear utility power. (b) The specific site is based on using gas and/or oil as the separate generation boiler fuel. (c) The local utility will at least tolerate, or work with, the industrial cogenerator. (d) The industrial site has a minimum heat-to-power ratio of about 1.0 or the local utility will pay a fair price for the power exported from the industrial site. If all or most of the above conditions are met or approached, the industrial site owners should consider cogeneration. The steam cogeneration systems can provide the industrial owner an attractive return-on-equity and return-on-investment. However, the emerging technology of the closed cycle gas turbine shows a return-on-equity significantly better than that for the equivalent steam cogeneration system as shown in Figure 3. The significance of the Task I and Task II effort to the industrial sector is that these parts of the study verified the results of Task III by conducting a detailed cost and thermodynamic analysis on a selected industrial site cogeneration system.
