Video – “Captor Hoods – Basic Principles and Design Theory/Equations”
Latest OXYL8 LEV training video (Aug 17) on YouTube which provides an introduction to the basic operational principles of Captor Hoods and an outline of the mathematical theory for Captors.
Fletchers Nomogram equations are discussed and reference made to an OXYL8 (free to download) Excel spreadsheet which will do all the hard number crunching for Fletcher’s Equations in a trice!
Using the spreadsheet it is possible to calculate in seconds – the required Hood Entry (Face Velocity) required for a given size and shape of hood, with the process operating at a pre-determined distance from the hood entrance.
The free design spreadsheet can be downloaded here:- Fletcher Excel Spreadsheet (see bottom of link page)
