The invention relates to a heat exchange device comprising a channel wall defining a flow channel with an inlet for receiving a gas flow. The device further comprises one or more heat exchange surfaces positioned inside the flow channel creating different parallel flow paths for the gas flow through the flow channel, at least one of the heat exchange surfaces embedding one or more flow paths for a fluid heat exchange medium. The one or more deflection elements are positioned inside the flow channel and are attached to the channel wall to deflect the gas flow away from the channel wall.

Proposed is a connection tube support of a waste heat recovery boiler supporting a connection tube unit having a plurality of connection tubes that is disposed inside a waste heat recovery boiler and perform heat exchange between a fluid flowing inside and exhaust gas flowing outside, wherein the connection tube support includes a header storing fluid flowing through the connection tube unit and supporting one end of the connection tube unit by being connected to one end of the connection tube unit, and a tube sheet supporting a circumferential surface of each of the plurality of connection tubes, wherein the tube sheet has the plurality of connection tubes having been passed therethrough and is provided with a plurality of support holes respectively supporting circumferential surfaces of the plurality of connection tubes having been passed therethrough.

A spiral finned condenser is provided, which comprises: a condensing pipe and a fin; the fin is spirally wound on a surface of the condensing pipe; the condensing pipe forms a cubic structure by means of a plurality of turns and bends. The condenser further comprises a fixing bracket which is clamped and fixed on the condensing pipe. The condenser has the advantages of having a small size, a compact structure and good cooling effects.

Disclosed is: A casing of a heat recovery steam generator has a sidewall, and heat exchanger coil located therein capable of exchanging heat from hot exhaust gas flow into the casing, with a gap between the end of the coil and a sidewall. A baffle system for closing the gap after the coil is installed in the casing comprises a mount attached to the coil near the gap, and a baffle plate associated with the mount and movably supported thereby. The configuration of the mount and baffle plate are such to allow the baffle plate to be capable of moving from a retracted position withdrawn from the sidewall, to an extended position closing the gap. A retainer can hold the plate in the retracted position. The retainer can release, for example, by being temperature sensitive. The mount can have a support that engages the coil.

In a clip for holding a tube element, a first fitting part is provided on one side surface of the clip, and a second fitting part is provided on the other side surface. A back surface holding part is provided on an open side of the clip, and a front surface holding part is provided on an unopened side. Furthermore, a tongue piece is provided between the back surface holding part and the front surface holding part.
