Porter, R W

This study presents an evaluation of Organic Rankine Cycles (ORC) as combined with topping cycles incorporating gas turbines or diesel engines, and with subsequent waste heat utilization. The potential benefit of the proposed organic-Rankine-combined-cycle cogeneration of useful heat and electricity is more flexibility in meeting demands for the two products, by varying the mode of operation of the system. A thermal-economic analysis is developed and illustrated with cost and performance data for commercially available equipment, and with general economic parameters reflecting current regulations and market conditions. The performance of the ORC and of the entire combined cycle is described. Equations are presented for evaluating the various thermodynamic and economic parameters, and the resultant cash flows. Criteria are developed in order to assess whether or not the addition of an ORC to a cogeneration system without ORC is viable based on rate of return on incremental investment. Examples are given to illustrate how the method may be applied, namely to serve proposed commercial energy facilities for the North Loop Project and for Illinois Center, in Chicago. While results indicate that the proposed system is potentially viable, it is not viable under conditions prevailing in Chicago for the selected case studies.
