Techno-Economic Design Tools Used in Selecting Industrial Energy Recovery Systems
This paper presents computer-based procedures used to perform techno-economic evaluations of industrial heat sources as candidates for energy recovery. The procedures are based on four versatile and easy-to-use computer models, two for technical evaluations and two for economic evaluations. The four models are explained in detail and are applied to several industrial heat recovery examples. Given a specific heat source, the technical evaluation consists of determining the energy recovery system's design, performance, and initial installed cost. A flexible investment analyses is procedure forms the basis of the economic evaluation; payback period (in years) and percent of return on investment are calculated for competing alternative heat recovery systems, assuming that income is generated from avoided energy costs (that is, from the savings generated by using the heat recovery equipment). The documentation effort for the computer programs, relating to program use and program maintenance, is also explained.
