In this case it looks like LED6 is on, which points to a problem with the turbo temp being too high.? Not sure if this is the same for the NT20.? Maybe a failure of the temperature switch? When you press the stop button are you in local mode? If the controller is in remote mode, you may need to send the stop command through the software.

Re-tubing boilers is common. Properly done, the boiler's life is extended, not shortened. We are fans of retubing, especially on a relatively young boiler. How long should a boiler last? It depends greatly. A boiler should last 20 or more years, if water treatment is done properly (remove oxygen down to single digit part-per-billion range, soften/polish the hardness out, maintain an appropriate concentration of corrosion inhibitors). You mentioned that this boiler supplies humidification loads, which means 100% makeup water (process and heating boilers have return condensate, their makeup rates are much lower, 10-20% makeup). 100% makeup needs excellent water treatment to prevent corrosion in the boiler (which causes the tube leak). If you can't implement good treatment, you will be back in 7 years replacing tubes. With good treatment, it can go 20 years. One issue some facilities have with humidity-producing boilers is a desire to avoid using corrosion inhibitors as they are concerned they could be deleterious to human health when added to air. When running with no corrosion inhibitors and a carbon steel boiler, a boiler will not last long at all.

One boiler has tubes that have leaked and we can either re-tube the boiler (7 years old) or purchase a new boiler. What is the collective wisdom out there around the risk of lifetime of a re-tubed boiler? Thanks and Happy 4th Rick Richard H.

In-Reply-To: References: Message-ID: <5D1F7C15.5040204@cns.fas.harvard.edu> Hi Ryan, Here at Harvard CNS, we don't have a specific response plan for an "unknown odor". We have ambient gas sensors for all of the toxic gases that we use, and flow sensors for the fume hood exhaust, both of which trigger cleanroom evacuations as necessary. However, when we do encounter an unknown odor, we pursue it vigorously, to make sure it is not a sign of trouble. For chemical spills, even of relatively benign materials, our protocol is to evacuate the cleanroom if any detectable odor is noted during or after cleanup, even if hand-held VOC sensors don't sense anything. The reason for this is to prevent potential exposures to our more sensitive/vulnerable users (pregnant women, etc). Typical issues have involved photoresist trash bags (which we now double-bag in front of a fume hood to minimize odors). One of the more tricky ones to isolate was when someone was baking resist on full wafers, in an unvented oven outside the photo bay. Took us quite a while to isolate that one.

If anyone can share an overview of your procedures or any information regarding actual incidents involving unknown odors and methods to safely determine the source of the odor that would be great.

Rick From: Maxwell, Dan [mailto:DMaxwell at hallam-ics.com] Sent: Wednesday, July 03, 2019 4:19 PM To: Morrison, Richard H., Jr ; labnetwork at mtl.mit.edu Subject: RE: Steam boiler question Rick: I have run your question by our Director of Engineering. Re-tubing boilers is common. Properly done, the boiler's life is extended, not shortened. We are fans of retubing, especially on a relatively young boiler. How long should a boiler last? It depends greatly. A boiler should last 20 or more years, if water treatment is done properly (remove oxygen down to single digit part-per-billion range, soften/polish the hardness out, maintain an appropriate concentration of corrosion inhibitors). You mentioned that this boiler supplies humidification loads, which means 100% makeup water (process and heating boilers have return condensate, their makeup rates are much lower, 10-20% makeup). 100% makeup needs excellent water treatment to prevent corrosion in the boiler (which causes the tube leak). If you can't implement good treatment, you will be back in 7 years replacing tubes. With good treatment, it can go 20 years. One issue some facilities have with humidity-producing boilers is a desire to avoid using corrosion inhibitors as they are concerned they could be deleterious to human health when added to air. When running with no corrosion inhibitors and a carbon steel boiler, a boiler will not last long at all.
