摘要： Aspects of the invention provided herein include heat engine systems, methods for generating electricity, and methods for starting a turbo pump. In some configurations, the heat engine system contains a start pump and a turbo pump disposed in series along a working fluid circuit and configured to circulate a working fluid within the working fluid circuit. The start pump may have a pump portion coupled to a motor-driven portion and the turbo pump may have a pump portion coupled to a drive turbine. In one configuration, the pump portion of the start pump is fluidly coupled to the working fluid circuit downstream of and in series with the pump portion of the turbo pump. In another configuration, the pump portion of the start pump is fluidly coupled to the working fluid circuit upstream of and in series with the pump portion of the turbo pump.

摘要： A turbopump system includes a pump portion including a housing having a pressure release passageway disposed therein. The pump portion is disposed between a high pressure side and a low pressure side of a working fluid circuit. A drive turbine is coupled to the pump portion and configured to drive the pump portion to enable the pump portion to circulate a working fluid through the working fluid circuit. A pressure release valve is fluidly coupled to the pressure release passageway and configured to be positioned in an opened position to enable pressure to be released through the pressure release passageway and in a closed position to disable pressure from being released through the pressure release passageway.

摘要： A heat engine system and a method are provided for generating energy by transforming thermal energy into mechanical and/or electrical energy, and for controlling a thrust load applied to a turbopump of the heat engine system. The generation of energy may be optimized by controlling a thrust or net thrust load applied to a turbopump of the heat engine system. The heat engine system may include one or more valves, such as a turbopump throttle valve and/or a bearing drain valve, which may be modulated to control the thrust load applied to the turbopump during one or more modes of operating the heat engine system.

摘要： Aspects of the invention disclosed herein generally provide heat engine systems and methods for generating electricity. In one configuration, a heat engine system contains a working fluid circuit having high and low pressure sides and containing a working fluid (e.g., sc-CO2). The system further contains a power turbine configured to convert thermal energy to mechanical energy, a motor-generator configured to convert the mechanical energy into electricity, and a pump configured to circulate the working fluid within the working fluid circuit. The system further contains a heat exchanger configured to transfer thermal energy from a heat source stream to the working fluid, a recuperator configured to transfer thermal energy from the low pressure side to the high pressure side of the working fluid circuit, and a condenser (e.g., air- or fluid-cooled) configured to remove thermal energy from the working fluid within the low pressure side of the working fluid circuit.
