    Abstract: Methods and systems relate to an oxy-boiler used to generate steam injected into a well for assisting recovery of hydrocarbons. Operating conditions of a burner for the oxy-boiler limits oxygen contamination in a resulting flue gas for carbon dioxide recovery and limits size of the oxy-boiler, which may thus be located proximate the well rather at a central processing facility. In contrast to a direct steam generation approach where resulting carbon dioxide is mixed with steam, the oxy-boiler also enables selection of a desired level of carbon dioxide injection, which may be provided with the flue gas that may be exhausted from the oxy-boiler at an injection pressure.

Because these actuators have no rotating or sliding mechanical components, wear and associated maintenance are reduced. Each deformable actuator has a portion made of shape memory alloy that has been trained to change shape in a specific manner when heated to a temperature above a transition temperature. In addition, each shape memory alloy actuator is shaped to act as a fairing to reduce aerodynamic drag.

  • Patent number: 8601815
    Abstract: A system and method for generating, transmitting and receiving power includes providing a source of non-optical power, such as thermal energy, which is converted into electricity. The non-optical power is converted into an optical power beam which is directed into a hollow pipe and transmitted along a length thereof. The hollow pipe may have an inner reflective surface, or lenses or collimators to direct the light therethrough. Upon exiting the hollow pipe, the optical power beam is converted into electricity.

  • Publication number: 20130305722
    Abstract: A method for operating a steam power plant at low load is suggested comprising the extraction of live steam LS before the last superheater SH3 and/or resuperheated steam before the last resuperheater RSH2 and using the thermal energy of this steam in other heat sinks. Thus, nearly constant steam parameters of the live steam LS are achieved and the overall efficiency of the steam power plant remains at a high level.
