UNIT FOR RECOVERING HEAT OF EXHAUST GASES OF TESTED JET GAS-TURBINE ENGINE Russian patent published in 1994 - IPC

FIELD: application of waste heat of engines. SUBSTANCE: all heat-exchange apparats are turned on at maximal temperature of exhaust jet (near 2000 deg.). Adjustable flaps are mounted in perpendicular to flow of exhaust jet and are closed. The other adjustable flaps are mounted in parallel to the flow. When temperature of gas jet is significantly lower than 2000 deg., the adjustable flaps are placed into the position to prevent access of exhaust gases to heat-exchange apparatus being switched off. After being cooled in heat-exchange apparatus, exhaust jet enters exhaust pit. EFFECT: improved efficiency of operation. 1 dwg
