Jet steam engine

Abstract

A simply constituted steam engine efficiently obtains mechanical energy not only from a heat source of a high temperature but also from the exhaust heat of an internal combustion engine and various kinds of heat sources of a low-temperature state such as the solar heat. In the engine, a rotor (5) having a folded jet pipe (51) is rotatably supported in a sealed container (1) filled with a liquid. A heating portion (9) is inserted in a center cylinder (50) at the center of the rotor, and a fluid of a high temperature is passed therethrough to vaporize the liquid sucked through the suction pipe (52) of the rotor (5). A mixture of steam and liquid is jetted from the jet pipe (51) due to the pressure of the steam that is vaporized to rotate the rotor (5) . A check valve (53) for jetting and a check valve (54) for suction are disposed at the ends of the jet pipe (51) and the suction pipe (52). The jetted steam is guided to a condenser (2) disposed on the sealed container (1), and is condensed and is refluxed into the sealed container (1). A vacuum pump (23) is connected to the condenser (2), and the pressure in the sealed container is held at the saturated steam pressure.

Description

technical field [0001] The present invention relates to a steam engine for converting thermal energy into mechanical energy such as rigid body kinetic energy, and in particular to a steam engine that efficiently generates mechanical energy from a relatively low-temperature heat source. Background technique [0002] In recent years, from the viewpoint of environmental protection, resource saving, and energy saving, the development of utilization technologies of various energy resources has progressed. Among them, there are technologies for obtaining mechanical energy from thermal energy existing in nature such as solar energy. In addition, a technology has been developed that uses exhaust gas from an internal combustion engine such as a diesel engine or waste heat discarded to coolant to generate power and recovers the power to improve the thermal efficiency of the internal combustion engine. [0003] A heat engine (engine) is used when converting thermal energy into mechanic...
