The RMH Group served as mechanical, electrical, and controls engineer for a project to add cogeneration capabilities to BYU-Idaho’s Rexburg campus heating plant. The project began with a conceptual study/economic analysis, which investigated the economic viability of adding cogeneration capabilities. Following completion of the conceptual study/economic analysis, RMH provided follow-on design for installation of a nominal 5.7MWe natural gas turbine with 50,000 pph HRSG that was calculated to have a simple payback of eight years. RMH’s design for the gas turbine featured a fully enclosed evaporative cooling system to increase the turbine output, as well as a turbine enclosure heat reuse system. These turbine system enhancement packages have less than a two-year payback, further improving the overall system payback.
