Abstract
A steam engine (10) has an engine case (14), a stator (20) with a radially-inner surface (52) with a plurality of recesses (54), a steam generator (12) and a rotor 5 (22) that has a steam distribution chamber (44) arranged to receive steam from the generator and a plurality of steam distribution channels (46) having outlets (50) for the flow of steam into the stator recesses (54). The rotor has pressure relief ports (60) for the flow of steam from the recesses (54) into the engine case (14) and then to a condensation circuit (66). The engine operates without a boiler and produces 0 steam by injecting water into the generator (12) where it is rapidly vapourized. The rotor (22) is the only moving part and the engine can produce a wide range of power outputs.
