A preliminary design for a Dresser-Rand DC990 industrial gas turbine engine modified for intercooling and recuperation (ICR) is presented. The DC990 was selected because its configuration is amenable to intercooling and because it is in the power range of interest. Based upon preliminary estimates, engine power output will increase from 6000 bhp to 8400 bhp at design point. Design point specific fuel consumption will be reduced 26% to a heat rate of 6300 BTU/bhp-hr. Moreover, the DC990 ICR engine maintains a high thermal efficiency during part-load operation. These performance improvements are achievable using proven, low-risk technology. The resulting combination of low fuel consumption and low maintenance costs makes the DC990 ICR gas turbine engine an attractive engine package for several applications.
