Steam Sparger Velocity Restriction - Industrial ...

2011-1-20  I have to design a steam sparger system.I am getting confused about the velocity restriction in the spargers. In some document I 'm finding it should be lower than 4 cm/sec,Where as in document from MOTT corporation the restriction for non agitated system is 0.68m/sec. Also from some document I am finding that the restriction of hole size is 3-8mm.

Sparger Design Guide - Mott Corporation

2020-6-5  Sparger sizing is based on the superficial gas exit velocity from the porous sparger surface, expressed in feet per minute (FPM), calculated from actual cubic feet per minute per square foot of sparger surface area (ACFM/Ft.2). ACFM is calculated at the liquid pressure and temperature at the sparger,it is not based on gas pressure.

Steam Sparger Calculation - Student -

2011-11-9  Please check your heat balance again. 124 kW is 124 kJ/second, or 4.46e5 kJ/hour. At 2 bar g the latent heat of steam is about 2160 kJ/kg, making the steam flow about 210 kg/hour. But this is for heating only. If you need steam for stripping the color and odor you will need more than this. Knaebel Sparger.pdf 122.19KB 413 downloads

Pool stratification and mixing induced by steam

2018-10-1  The inclination was attributed to the downwards component of the steam velocity at the sparger hole outlet. This component is not negligible since the area ratio between injection hole to pipe cross section is about 0.41 and the wall thickness is only 4 mm, not big enough to re-direct the flow to a complete horizontal direction.

Multiple-hole effect on the performance of a sparger ...

An experimental study has been carried out to investigate an I-type sparger performance in view of pressure oscillation and thermal mixing in a pool. Its pitch-to-hole diameter, P/D, varies from 2 to 5. The test conditions are restricted to the condensation oscillation regime. In the present study, two different hole patterns, staggered and parallel types, are employed under various test ...
