A tube and shell heat exchanger with annular distributor has openings ... said annular space extending in direction of the heat exchanger axis from an area where this annular space surrounds a portion of the flow space within the shell in the proximity of the tube sheet to beyond the shell side surface of said tube sheet in the direction toward ... Design Method For Annular Distributors - Process Heat ... When the required slot area becomes too large, you may have to change other dimensions of the exchanger (e.g. length, diameter, baffle spacing, etc) to properly fit the annular distributor. It bothers me to have to change my exchanger design just because of an annular distributor design method that I don't fully understand. Open Area Calculator | Hendrick Manufacturing

How to determine which impingement protection method is best An annular distributor can be installed along with an expansion joint to save on cost and space. If an exchanger's processes easily give way to thermal expansion, this is a good solution. The installation will help to reduce erosion and vibration, but will also help decrease risk of uneven expansion that could damage the shell or the tubes. Tube and shell heat exchanger with annular distributor Sep 10, 1985 · In accordance with this invention a tube and shell heat exchanger is provided having an annular distributor surrounding the shell in the area where the shell is attached to the tube sheet and extending past the shell side surface of the tube sheet. Preferably the annular distributor extends significantly past the entire tube sheet. US Patent for Method for varying shell fluid flow in shell An annular distributor is conventionally designed such that the ratios of nozzle-to-annulus flow area and annulus-to-slot flow area provide a recovery of static pressure by virtue of reduced momentum with passage through the nozzle, annulus, and shell slots.
