A conceptual design study of an air preheater system for the MHD Component Development Integration Facility (CDIF) at Butte, Montana was performed. This heater will be part of the facility and will provide hot air for combustor testing. System reliability and low maintenance are emphasized; control accuracy within 1 percent of absolute temperature and pressure and repeatability are required. The system is to heat 20 lbs/sec of air at a maximum inlet pressure of 190 psia and at an outlet temperature of 3000/sup 0/F with 1500/sup 0/F inlet. Operation at lower airflow pressure and temperature is required. A complete statement of the design requirements is given. Systems using two to six heat exchangers operating in series and parallel modes were studied. The trade-off studies provided comparative measures of capital cost, operating cost, utility requirements, leakage losses, sizes and other engineering detail. A system arrangement was selected based on these studies. Conceptual design drawings and an engineering analysis were prepared, program plans for design and construction were defined, and estimates were made of cost and schedule. A system with four heat exchangers operating in staggered parallel was selected. This system is sized for full operation on three heat exchangers allowing one unit to be down for repairs. Plan and elevation views of the selected system are shown.
