    • A drive system for driving a load (21) by means of a gas turbine (3). The gas turbine comprises a gas generator (5) having a gas-generator rotor (5R) and comprising at least one gas-generator compressor (9) and one high-pressure turbine (11) driving the gas-generator compressor. The gas turbine further comprises a power turbine (7) having a power-turbine rotor (7R), which is torsionally independent of the gas-generator rotor (5R). The load is connected to the power-turbine rotor (7R). The system further comprises an electric motor/ generator (23) mechanically connected to the gas-generator rotor (5R) and electrically connected to an electric power grid (G). The electric motor/generator (23) is adapted to function alternatively: as a generator for converting mechanical power from the gas turbine (3) into electrical power; and as a motor for supplementing driving power to the load (21). A set of movable nozzle guide vanes (15) is arranged at the inlet of the power turbine (7).

    • A power generation system that includes a heat source loop, a heat engine loop, and a heat reclaiming loop. The heat can be waste heat from a steam turbine, industrial process or refrigeration or air-conditioning system, solar heat collectors or geothermal sources. The heat source loop may also include a heat storage medium to allow continuous operation even when the source of heat is intermittent. Heat from the heat source loop is introduced into the heat reclaiming loop or turbine loop. In the turbine loop a working fluid is boiled, injected into the turbine, recovered condensed and recycled. The power generation system further includes a heat reclaiming loop having a fluid that extracts heat from the turbine loop. The fluid of the heat reclaiming loop is then raised to a higher temperature and then placed in heat exchange relationship with the working fluid of the turbine loop. The power generating system is capable of using low temperature waste heat is approximately of 150 degrees F or less. The turbine includes one or more blades mounted on a rotating member. The turbine also includes one or more nozzles capable of introducing the gaseous working fluid, at a very shallow angle on to the surface of the blade or blades at a very high velocity. The pressure differential between the upstream and downstream surfaces of the blade as well as the change in direction of the high velocity hot gas flow create a combined force to impart rotation to the rotary member.
    • 一种发电系统,其包括热源回路,发动机回路和热回收回路。 热量可以是来自蒸汽轮机,工业过程或制冷或空调系统,太阳能集热器或地热源的废热。 热源环路还可以包括一个热存储介质,即使当热源间歇时也允许连续的操作。 来自热源环路的热量被引入热回收回路或涡轮机回路中。 在涡轮机循环中,将工作流体煮沸,注入涡轮机,回收冷凝和再循环。 发电系统还包括具有从涡轮机回路提取热量的流体的热回收回路。 然后将热回收回路的流体升高到更高的温度,然后与涡轮机回路的工作流体进行热交换。 发电系统能够使用低温废热约为150华氏度以下。 涡轮机包括安装在旋转构件上的一个或多个叶片。 涡轮机还包括一个或多个能够以非常浅的角度将气态工作流体以非常高的速度引导到叶片或叶片的表面上的喷嘴。 叶片的上游表面和下游表面之间的压差以及高速热气流的方向的变化产生组合的力以赋予旋转构件旋转。
