I should have been clearer, we mix two gas streams for burner fuel gas for the 4 big boilers. One stream is natural gas coming in by pipeline, the 2nd stream is the gas / h2s mix were its 32% h2s. The h2s gas mix makes up 15% of final mix after adding in pipeline gas, so our burners see only about 4.8% h2s. You only need 100ppm h2s to be lethal so...
I see absolutely nothing wrong with that.
ReplyDeleteThanks Phil, the inspector withdrew his strike on me as well....
DeleteI wouldn't accept that on ours, we burn 32% h2s in ours and because of that everything is welded and no brass.
DeleteOn a commercial unit its fine

As a former electrician, looks good to me! lol
ReplyDeletePeople still use gate valves?
ReplyDeleteYeah, I didn't quite understand that multi-valve setup on that line, and the pipework didn't look great. This is much better.
