Cold Flare Vs Dry Flare
Cold Flare Vs Dry Flare
(OP)
Dear Eng Tips Community
Kindly any of you can explain briefly the different between Dry Flare and Cold Flare, it is associated with HP or LP flare? Is the Ignition system between them different?
I googling, but still not get good definition of that terms.
Thanks for your response and answer

So a cold or dry flare could be either a HP or LP flare system.
Remember - More details = better answers
Also: If you get a response it's polite to respond to it.
RE: Cold Flare Vs Dry Flare
As far as I know, either flame front generator or spark ignition type ignition systems can be used for any of these - redundancy in some of the subcomponents (including thermocouples for flame detection) for either of these is preferable. Talk to the flare tip vendor for many other details. If redundancy is provided, then overall reliability would be about the same for either types.
Typical problems associated with flares are
Failure to light up on startup
Flare tip thermal damage due to inferior materials or flame lick
Carbon deposition on the flare on LP flares and sometimes on HP flares
Smoky flares.
Some of these problems are due to operating the flare at low flows resulting in incomplete combustion and flame lick. Providing air or steam assist is often done on LP flares and for operational HP flare loads to enable good turndown and smoke free operation. In high H2S operation, sulphur deposition due to incomplete combustion around the flare tip is a danger.
