摘要： Provided herein are a heat engine system and a method for generating energy, such as transforming thermal energy into mechanical energy and/or electrical energy. The heat engine system may have a single charging pump for efficiently implementing at least two independent tasks. The charging pump may be utilized to remove working fluid (e.g., CO2) from and/or to add working fluid into a working fluid circuit during inventory control of the working fluid. The charging pump may be utilized to transfer or otherwise deliver the working fluid as a cooling agent to bearings contained within a bearing housing of a system component during a startup process. The heat engine system may also have a mass control tank utilized with the charging pump and configured to receive, store, and distribute the working fluid.

摘要： The present invention is directed at the thermodynamic property amplification of a given thermal supply, provided by hydrocarbon combustion or in the preferred application heat provided by low-grade geothermal energy from the earth, for a vapor power cycle. The present invention achieves the desired objectives by segregating the compressible supercritical energy stream from the heat exchanger (boiler) into hot and cool fractions using a vortex tube, where the hot temperature is elevated above the heat exchanger temperature; and adding back heat (enthalpy) to the cool stream increasing the cool temperature to that of the geothermal heat exchanger. The heat-exchanger (boiler) supercritical gaseous mass flow segregated by a counterflow vortex tube (or bank of vortex tubes) forms hot and cool fractions where the hot temperature is raised above the heat-exchanger supply temperature, and heat (enthalpy) is added to the cool stream thereby increasing the cool temperature to that of the heat exchanger supply temperature.

摘要： A method of increasing the efficiency of a power cycle of a steam turbine at supercritical steam conditions comprises the steps of, first expanding the working medium at supercritical steam conditions to a pressure higher than the critical pressure and then dividing the working medium into first and second streams. The first stream is expanded in the turbine, with interstage reheating, and multi-stage regenerative feed water heating is effected by condensing extraction steam and cooling the second stream by heat exchange with the feed water preliminary heated by the regeneration extractions whereupon the second stream is mixed with the feed water and returned to the first expanding step to complete the cycle.
摘要翻译：一种在超临界蒸汽条件下提高蒸汽涡轮机的动力循环效率的方法包括以下步骤：首先在超临界蒸气条件下将工作介质膨胀至高于临界压力的压力，然后将工作介质分成第一和第二流。第一流在涡轮机中膨胀，级间再加热，多级再生给水加热是通过冷凝提取蒸汽并通过与再生提取预先加热的给水进行热交换来冷却第二流来实现的，因此第二流是与进料水混合并返回到第一个扩展步骤完成循环。
