The work was undertaken to formulate a quantitative mechanism which would facilitate evaluation of power plant waste heat utilization potential. Heat at usable temperatures is made available by extraction from the turbine. Incremental rates for reductions in electric output and heat rejection are obtained for various amounts and locations of waste heat extraction. The maximum justifiable investment MJI, for a waste heat system, is calculated using a present worth criterion and at constant thermal input to the turbine cycle. A series of thermal market prices is applied in order to determine the sensitivity of the MJI to potential market values. Results for a typical medium sized plant are summarized. Author
