Thanks for the info and sharing your knowledge
I’ve done the repair/replace engineering on petroleum and natural gas fires with far less fuel feeding the fire.
It is amazing how much damage can be done in a 4 hour burn. Steel structures that were coated with fire protection that now simply don’t exist.
(The fire protection material does work, the equipment or valving last long enough to get the shutdown procedures accomplished so the fire doesn’t continue to burn new sources of fuel.)
