I have a problem that pops up every now and then that seems like it should be easily understandable and easy to fix.
I work on the 18 kw electric boiler that supplies steam to the steam room in one of the first athletic clubs in the USA. I have the steam pressure set for 5 psig on the boiler. I...
The bad out of the box Honeywell FSG control.
A week after I replaced the second control I received a call from my friend at Honeywell. I expected the call since I marked the two control I sent back to his attention. He asked me how the new control was working and I told him just find. Then he...
Wow, the long post I just typed disappeared before I posted it. I have a love/hate relationship with this new wireless Apple mouse. Anyway, less than 2 hours till Ash Wednesday. It's hard to imagine but at the moment the French Quarter has maybe 150,000 to 200,000 people in it, 90% drunk and by...
Hey people, don't you know it's Fat Tuesday??
This is the down side to smart phones. It's Mardi Gras, I'm in the French Quarter of New Orleans. There are so many people on Bourbon Street that it takes 20 minuets to cross the street. There are at least 700,000 people on Canal Street waiting for...
Good post jraef
Initially I did assume that external source was an electrical service of some kind but then I realized it could be anything.
The only thing I disagree with you on is, "But from a forensic standpoint, what Yaskawa is saying is, it wasn't the result of a failure of one of their...
Skogsgurra, you are probably right but guesses are not what I was looking for. The front end of the drive was pristine, even under a 10x ocular. If 'itsmoked' is correct in that it is possible to short certain front end terminals together or a terminal to ground and cause the damage found in...
"PLEASE no need to comment on this next step" was an effort on my part to inform everyone that I fully understood how foolish it is to work inside a hot panel, VFD or not, 120 v or 480 v. I get it. I worked on radars in the military that operated at over 50kv. After de-energizing the system you...
I installed two new identical Yaskawa VFD Model CIMR-P7U47P51B-107 to drive new identical 10 hp 480Vac 3ph motors. This was as simple an application of VFDs as you get. No network control, nothing unusual. The only problem I had was terminating the signal wires that connected the two units so...
I just received my copy of ASME PTC 4 2008 and was surprised to find it didn't include a short form for the so called abbreviated efficiency test like PTC 4.1 did.
Is the short form no longer used?
Where can I get a copy of the short form from PTC 4.1?
I can't find a good copy anywhere on the...

rmw, you're right, natural gas should burn clean and usually does. That's a tribute to modern gas burners but the combustion of natural gas is a little more complicated than is usually shown in text books. The equation of methane is often used to illustrate the combustion of natural gas as
CH4 +...
Having spent 36 years in the boiler business I've seen a lot of sooted up boilers but I never gave a lot of thought to the soot distribution on the heating surfaces. But now I'm writing a book on packaged boilers and would like a better explanation than.. 'that's just the way it is."
I'm...
I'm starting a project to upgrade the control system on a 600 hp steam boiler. I could use AutoFlame but would prefer not to. I have no experience with Honeywell's ControLink system but it looks on paper to meet my needs.
Anyone with experience with the system?
Thanks
Steve
