Benefits of technology

[0008]Among the benefits of this system are a smaller total condenser package, more efficient steam distribution and the potential for using “hyper thin” wall tubing. This system for supporting tubes changes the flow characteristics of the shell side fluid resulting in an enhanced condensate rate. This technology is particularly suited to utility-sized applications which require the suspension of thousands of individual tubes. Finally, maintenance costs are greatly reduced because the tubes are better protected from both mechanical and chemical damage, while heat transfer is more uniformly maintained throughout the bundle.

Problems solved by technology

The type of support plates which promote longitudinal flow, however, do not possess adequate strength to withstand the stresses that follow from greater flow and require alternate ways of strengthening the structure around them.
Problems with insufficient reinforcement include flow-induced vibration which can cause tube damage.

Embodiment Construction

[0015]Referring now to FIG. 1, an exterior view of the installation 10 which includes two steam surface condenser shells 11 and 13 utilizing the support system of the present invention is shown. This Figure depicts the tube bundle 15 being slidably removed from one of the condenser shells 11 with the tube bundle 15 riding on rails 17 which carry the tube bundles by their support plates 19.

[0016]Referring now to FIG. 2, a typical tube bundle module is shown with the individual tube support plates 19 being supported by a pair of longitudinal framework members 21 along each side. The framework members extend between end plates 23 so that the individual tubes are supported along their entire length.

[0017]Regarding FIG. 3, the need in the art for high performance steam condensers with proper internal support of the shell sidewalls 31 (shown in phantom), is provided by the framework shown. The shell reinforcement of the invention keeps the shell sidewalls from collapsing inwardly due to t...

Abstract

A condenser shell internal support structure includes horizontal rails and vertical beams which can individually support a variety of shapes and configurations of tube bundle modules. Each module includes an end frame and longitudinal framework members that hold each of the parallel tube bundle support plates. The reinforcement framework supports at least one tube bundle and also opposing sidewalls of the shell. The framework further comprises laterally disposed crossbeams extending between and affixed to the opposing shell sidewalls.

Description

RELATED APPLICATION[0001]This patent application is related to provisional patent application Ser. No. 61 / 186,646 entitled “Condenser Shell and Tube Bundle Support Plate Construction” filed on Jun. 12, 2009, priority from which is hereby claimed.FIELD OF THE INVENTION[0002]This invention relates to the construction of a heat exchanger condenser shell which houses a plurality of tube bundles held in position by support plates.BACKGROUND OF THE INVENTION[0003]The heat exchange condenser transfers heat from one fluid to another by passing one fluid through tubes housed within an outer shell through which a second fluid such as steam passes that contacts the surface of the individual tubes. The second fluid passes through the interior of the shell so as to heat or cool fluid within the tubes. Examples of this technology is shown in several of my previous patents for example, U.S. Pat. No. 4,579,304 entitled “Tube Bundle Support” and my pending patent application published as US2009 / 0032...
