: Kind of scary how many places are starting to go with low surface area boilers to get around regulations. It is only a matter of time before someone is seriously injured.
I doubt it will be the low water content boiler itself that actually kills somebody. I think it will be the casual attitute toward steam and hot water under pressure that they foster. Plant management routinely (and incorrectly) assumes that because they no longer require licensed operators, that they're now not under ANY regulations.
From what I've seen, it will be a piping failure, or more likely, a deaerator failure that kills somebody. I've seen a number of DAs in low water content plants that have a faction of the safety valve capacity they should have, based on the size of the steam PRV that feeds them.
