So this Boiler trip.
My inside job has three 43bar Stork HP boilers as part of my responsibility.
Had to change fuel from fuel oil and fuel gas to just fuel gas. Outside guy shut correct valves at correct time, all groovy. Then an alarm sounded and the emergency low pressure fuel safeguard activated.
So no fuel at all now.

So the down wiggle top right trend box is the total refinery steam pressure. Got down to 38bar from 43.
The boiler output that tripped lower left. The other boiler picking up some load lower right.
Had liquid fuel fires back in within 5 minutes and then sent someone to check what went wrong, all the time wondering if it was a mistake on my part. Outside guy found a wire hanging out of a termination box. Clearly broken previously and never reported. Vibration from fuel change must have shaken it loose therefore 'zeroing' instrument.
Had our favourite instrument guy remake the lead and carried on with the job.
I made this face.

Refining. 99% boredom, 1% terror.
