A trans-critical thermodynamic system includes an expansion device and a separator. The expansion device receives a supercritical fluid containing solutes. The expansion device is operable to expand the supercritical fluid to produce a sub-critical gas by reducing a temperature and/or a pressure of the supercritical fluid. The separator removes the solutes from the sub-critical gas.

Trans-critical thermodynamic system and method for removing solutes from fluid

A sensor assembly is shown for sensing a crossing of the critical point in a system utilising a working fluid in a transcritical cycle passing through the critical point. A first broadband acoustic sensor is located upstream of a component and a second broadband acoustic sensor is located downstream of the component, each of which are arranged to detect high-frequency and low-frequency sounds caused by the crossing of the critical point. A flow regulation device regulates flow of working fluid through the component in response to the output of one or both of the first broadband acoustic sensor and the second broadband acoustic sensor, thereby adjusting the location of the crossing of the critical point.

Sensor assembly

A turbomachine () configured to compress supercritical carbon dioxide is shown. The turbomachine comprises, in fluid flow series, an inlet (), an inducerless radial impeller () having a plurality of blades, and a fully vaneless diffuser (). The radius of the inlet (r) is from 25 to 50 percent of the radius of the impeller (r).

Turbomachinery

A turbomachine () configured to compress supercritical carbon dioxide is shown. The turbomachine comprises, in fluid flow series, an inlet (), an inducerless radial impeller () having a plurality of backswept blades () each of which have a blade exit angle (&#x3c7;) of from &#x2212;50 to &#x2212;70 degrees, and a fully vaneless diffuser ().

A steam generator comprising a vessel having an inlet and an outlet, and in use a primary fluid flow enters the vessel through the inlet and exits the vessel through the outlet. A plurality of modules are connected in series and at least partially housed within the vessel, and each module comprises at least one tube. The modules are arranged such that at least one tube of one module is coaxial with at least one tube of an adjacent module so as to define a conduit through which a secondary fluid can flow from one module to an adjacent module.

Steam generator

There is disclosed herein a heat exchanger and an associated method of manufacture. The heat exchanger comprises a flow conduit for accommodating flow of a heat transfer fluid. The conduit is wound around a central axis so as to form a plurality of turns, for example in a helical fashion. A support member for the conduit is formed of a sheet material shaped to extend in a circumferential direction about the central axis, wherein the support member is common to said plurality of turns. A plurality of fasteners are arranged to attach the conduit to the support member at spaced locations along its length.

Heat exchanger support

A rotary actuator has a driven element including a plurality of recesses that are spaced in a circumferential arrangement around an axis of rotation of the driven element by a spacing angle, and first, second and third latch elements that are each movable between a retracted position, and an extended position in which it is engageable with a corresponding one of the recesses. Sequential movement of the first, second and third latch elements between retracted and extended positions causes rotation of the driven element.
