Finned Tube Bundles
Tube Bundle construction is rigid and self-supporting in nature. Tube bundle consist of two headers, each at one end and connected with finned tubes. Tubes are usually made of Carbon steel tubes SA214 (ERW) but not restricted to this material of construction and fins of aluminium.
Typical design of tube bundle is either of the Single or Multi-rows tube design with a two pass arrangement of fluid through the tubes. The steam is condensed in the Condensing section of Bundles (referred as K Bundles) and the non-condensable gasses are extracted from the Dephlegmator Section (referred to as D-Bundles).
Single Row Tube Bundles
- Large area
- Low Pressure loss
Multi-Row Tube Bundles
- High Heat Transfer Coefficient
- Various type of fin configurations are available e.g. fins like KL,L,LL ,Extruded Fins.
