Dimple Jacket Heat Transfer Calculations

The dimple jackets are generally limited to 300 psig design pressure while half coil jackets can be used up to a design pressure of 750 psig.

Dimple jacket heat transfer calculations.

Heat transfer can be augment ed by increasing jacket velocities through the use of jacket baffles. Jacketed vessel heat transfer calculation estimates overall heat transfer coefficient for a vessel with an agitator along with heating cooling medium flowing in jacket spiral jacket or half pipe coil. For differential heating or cooling jackets can be segmented into zones. Dimple jackets are frequently used to heat or cool process vessels in the chemical process industries cpi.

Correlations used to determine the overall heat transfer coefficient and the frictional. Stamped dimple jacket is an efficient heat transfer surfaces for the most diverse range of in tank and on tank applications. Chemical engineering calculations to assist process plant operation and maintenance engineers. This module will deal with indirect heating.

For half pipe coil jacket the higher heat flux rate may require multiple sections of jackets to avoid having condensate covering too much of the heat transfer area. Dimple jackets have far better heat transfer characteristics than conventional jackets due to the turbulence gen erated by the dimples. Vessels can be heated in a number of different ways.
