A system includes a retention system configured to support a heat exchanger along a flow path within a duct. The retention system includes a first sleeve configured to extend between opposite first and second walls of the duct, a first cable extending through the first sleeve, and a first bumper coupled to the first sleeve. The first bumper is configured to contact the heat exchanger. The retention system includes a first tensioner coupled to the first cable, wherein the first tensioner is configured to provide a first tension in the first cable. The first tension is adjustable to detune the natural frequency of the heat exchanger away from any excitation load frequencies caused by an exhaust gas flow through the duct.

A heat exchanger includes a casing configured to direct a working fluid therethrough, and at least one heat exchanger (HE) section in the casing. Each HE section includes a pair of spaced supports. The spaced supports include: an upstream support and a downstream support with at least one of them including a coolant carrying body configured to direct a coolant therethrough. A first cross-support couples to and extends between respective upstream and downstream supports; and at least one second cross-support couples to and extends between the respective upstream and downstream supports. Cross-supports are vertically distanced from adjacent cross-supports. A plurality of tube positioners coupled to each cross-support position a plurality of heat exchange tubes extending across a working fluid path through the casing. The tube positioners and the cooling of the cross-supports allows ferritic material to be used for once-through, duct-fired HRSGs.

Multiple cooled supports for heat exchange tubes in heat exchanger

A heat exchanger includes a plurality of heat exchange tubes arranged into a first row of tubes and a second row of tubes. A fixed mount fixedly positions the first row of tubes, and a movable mount makes the second row of tubes movable between an aligned position in which tubes in the second row are aligned with tubes in the first row, creating a linear flow path for the fluid through the tubes, and a non-aligned position in which tubes in the second row are not aligned with tubes in the first row, creating a curvilinear flow path for the fluid through the plurality of tubes. Heat is exchanged between the first fluid and a second fluid passing through the plurality of heat exchange tubes. The heat exchanger may be employed as an HRSG in a combined cycle plant, among other applications.

An adaptor assembly includes: an adaptor piece including: a forged outer wall defining a substantially cylindrical shape; a through hole disposed at a top portion of the adaptor piece, the through hole defining an adaptor center cavity; a threaded portion disposed beneath the through hole; and a second hole disposed beneath the threaded portion. The adaptor assembly includes a hex socket including external threading. A diameter of the through hole is smaller than a diameter of the second hole. The hex socket is inserted through the second hole and screwed into the adaptor piece such that the external threading mates with the threaded portion.

In-line orifice

Disclosed herein is a once-through evaporator comprising an inlet manifold; one or more inlet headers in fluid communication with the inlet manifold; one or more tube stacks, where each tube stack comprises one or more inclined evaporator tubes; the one or more tube stacks being in fluid communication with the one or more inlet headers; where the inclined tubes are inclined at an angle of less than 90 degrees or greater than 90 degrees to a vertical; one or more outlet headers in fluid communication with one or more tube stacks; and an outlet manifold in fluid communication with the one or more outlet headers; and a baffle system comprising a plurality of baffles; the baffle system being disposed adjacent to a tube stack so that the baffle system contacts a tube.
