ABSTRACT:
Heat recovery systems are useful, for example, in vehicles that generate large amounts of heat energy during operation. The heat energy is used to drive a dual pressure turbine for producing useful work. In order to fully utilize the great majority of the heat energy produced, the engine exhaust is used to convert a fluid to a gas and superheat the gas to a preselected temperature at a preselected pressure. A first stage of the dual pressure turbine receives the superheated gas and directs the gas at a supersonic velocity against the blades of the rotor. The gas exiting the first stage and the superheated gas at a lower preselected temperature is controllably and substantially separately directed to a second stage at substantially the same velocity. This heat recovery system fully utilizes the heat energy generated by the engine and substantially eliminates the sooting and the formation of oxides within the exhaust system. The dual pressure turbine effectively utilizes the superheated gases to produce useful work at a high system efficiency.
