Rows of heat exchange tubes are supported by transversely disposed support strips having a plurality of U-shaped members interconnected end to end in a manner so that said strips act as a structural member supporting the weight of the tubes and additional support elements from all rows above a given row. Each leg of each U-shaped member converges upwardly or downwardly at an angle of about 8.degree. to 15.degree. with the vertical.

Support for heat exchange tubes

A heat exchanger is retrofitted by removing old heat exchange tubes. If there is no access passage into the shell, an access hole is cut in a wall of the shell. Modules preformed from zig-zag elements are introduced through the access passage and assembled into a tube support panel within the shell between adjacent support plates. The heat exchanger is retubed so as to support the new tubes by the existing support plates and by said panels.

Method of retrofitting a heat exchanger

A condenser shell for a large steam condenser is installed at a building site of a power plant without any tube bundles. One or more years later, the tube bundles are designed, constructed and installed in the shell.

Condenser construction with delayed tube bundles

Rows of heat exchange tubes are supported by transversely disposed support strips having a plurality of V-shaped members interconnected end to end in a manner so that said strips act as a structural member supporting the weight of the tubes and additional support elements from all rows above a given row. Each leg of each V-shaped member has a generally triangular tab bendable out of the plane of its associated leg.

An L-shaped member is used for positioning a plurality of tube support plates at predetermined spaced locations on the L-shaped member with the tube holes of the support plates aligned. The L-shaped member is portable and includes a plurality of longitudinally separated members for locating the tube support plates with a predetermined spacing between each tube support plate.

Method for constructing a steam condenser

The system for condensing gases such as steam includes a housing with a gas inlet. At least one vertical column of vertically spaced separate tube bundles are in the housing. A separate water conduit is connected to the inlet of each of the separate tube bundles.

Surface condenser with vertically separated tube bundles

An L-shaped member is used for positioning a plurality of tube support plates at predetermined spaced locations on the L-shaped member with the tube holes of the tube sheets aligned. The L-shaped member is portable and includes a plurality of longitudinally separated members for locating the tube support plates with a predetermined spacing between each tube support plate.
