Abstract
A non-vitiated compressed air heater facility that can heat a non-vitiated compressed air from around 1,100 degrees F. to over 1,600 degrees F. using three heat exchangers oriented in a vertical direction and connected in series, where each heat exchanger uses a number of heat pipes with burners to produce a hot gas at around 2,000 F that counter flows with non-vitiated compressed air flowing over the heat pipes to add heat to the non-vitiated compressed air flowing through the heat exchangers. The non-vitiated compressed air heated to at least 1,600 F can be used to test an aero vehicle in a wind tunnel under high Mach # conditions, or can be used to supply non-vitiated compressed air to test a large combustor of a gas turbine engine.
