摘要： A pair of organic rankine cycle systems are connected in series with the geothermal fluid passing first through an evaporator of the first system and then through an evaporator of the second system before returning to a sink. Similarly, the cooling tower is arranged to provide cooling water to pass first through the condenser in one system and then through the condenser of the other system, to reduce the total flow required and the size of associated cooling hardware.

摘要： A burner assembly includes a catalyzed burner for combusting an anode exhaust stream from a polymer electrolyte membrane (PEM) fuel cell power plant. The catalysts coated onto the burner can be platinum, rhodium, or mixtures thereof. The burner includes open cells which are formed by a lattice, which cells communicate with each other throughout the entire catalyzed burner. Heat produced by combustion of hydrogen in the anode exhaust stream is used to produce steam for use in a steam reformer in the PEM fuel cell assembly. The catalyzed burner has a high surface area wherein about 70–90% of the volume of the burner is preferably open cells, and the burner has a low pressure drop of about two to three inches water from the anode exhaust stream inlet to the anode exhaust stream outlet. The burner assembly operates at essentially ambient pressure and at a temperature of up to about 1,700° F. (927° C.). The burner assembly can combust anode exhaust during normal operation of the fuel cell assembly. The burner assembly also includes an adjunct burner which can combust gasoline or anode bypass gas (the latter of which is a reformed fuel gas which is tapped off of the fuel cell stack fuel inlet line) during startup of the fuel cell power plant. Once start up of the fuel cell power plant is achieved, the burner assembly will need only combustion of the anode exhaust by the catalytic burner to produce steam for the reformer.
摘要翻译：燃烧器组件包括用于燃烧来自聚合物电解质膜（PEM）燃料电池发电厂的阳极废气流的催化燃烧器。涂覆在燃烧器上的催化剂可以是铂，铑或其混合物。燃烧器包括由格子形成的开孔，该细胞在整个催化燃烧器中彼此连通。用阳极排气流中的氢燃烧产生的热量用于生产用于PEM燃料电池组件中的蒸汽重整器中的蒸汽。催化燃烧器具有高的表面积，其中约70-90％的燃烧器的体积优选为开孔，并且燃烧器具有从阳极排气流入口至阳极排气口约2至3英寸水的低压降流出口。燃烧器组件在基本环境压力下工作，温度高达约1,700°F（927℃）。在燃料电池组件的正常操作期间，燃烧器组件可以燃烧阳极排气。燃烧器组件还包括辅助燃烧器，其可在燃料电池发电厂启动期间燃烧汽油或阳极旁路气体（其中后者是燃料电池堆燃料入口管路中的重新燃烧的燃料气体）。一旦实现燃料电池发电厂的启动，燃烧器组件将仅需要通过催化燃烧器的阳极排气的燃烧，以产生用于重整器的蒸汽。

摘要： Embodiments of an ORC system can be configured to reduce ingress of contaminants from the ambient environment. In one embodiment, the ORC system can comprise a pressure equilibrating unit that comprises a variable volume device for holding a working fluid. The variable volume device can be fluidly coupled to a condenser so that working fluid can move amongst the condenser and the variable volume device. This movement can occur in response to changes in the pressure of the working fluid in the ORC system, and in one example the working fluid is allowed to move when the pressure deviates from atmospheric pressure.

摘要： A method and system for generating electrical power for sub-sea applications includes assembling each of the main components (132, 138, 142, 146) of an organic Rankine cycle (ORC) system (100) inside a pressure vessel to form a series of vessels (104, 106, 108, 110) removably connected to one another and configured to be placed near, on or below a sea floor. The main components of the ORC system include an evaporator (132), a turbine (138), a condenser (142) and a pump (146). A working fluid (135) is circulated through the pressure vessels in order to generate mechanical shaft power that is converted to electrical power (P). In some embodiments, the ORC system includes at least one redundant component that corresponds to one of the main components. The working fluid may be circulated through at least one redundant ORC component such that the ORC system is able to continue operating when one of more of the main components is not operating properly. A control system (148) is used to monitor operation of the main components and at least one redundant ORC component. In some embodiments, at least one redundant ORC component is housed in a pressure vessel with its corresponding main component. In other embodiments, at least one redundant ORC component is housed in a separate pressure vessel.
