Questions regarding the design specifications for the torch system
Thread Content
Which standard specifies that the diameter of the inner tube of the flare (the tube through which the combustion exhaust gases pass) should be greater than or equal to the diameter of the main vent pipe running from the flare liquid separation tank to the flare? If there are no relevant regulatory requirements, are there any examples of torch system designs that do not follow this theory? I would appreciate some guidance from the experts here.
I have communicated with torch manufacturers abroad, and foreigners only care that the emission resistance drop meets the requirements; they do not need to follow the aforementioned rules. Moreover, you have got this one backwards; the diameter of the main pipe inside the torch area should not be smaller than that of the main pipe outside the area.
