Fuse on steam download#
Just to clarify, I didn't download Fuse models on Steam, I downloaded Fuse (V1.3). It's frustrating being a noob at anything, but I'm slowly learning. Or so has been my experience.Hi and once more thank you for your help. If you are in a state that requires a licensed operator it might be happening, otherwise you can bet they are clueless and isn't taking place.
Fuse on steam how to#
Operators need to know this as well as how to test boiler safety controls at least once a shift per day.
There are certain steps that need to be followed in order to take a boiler on/off line. Likely some of them manufacturer involved too. I'm likely to think you have a combination of events happening, a lot of them operator involved. In the end you might need a good stationary engineer, a good chemical company rep, and a good electrician all working together to solve the underlying problem. The problem with the Warwick control system is it requires power to the boiler to operate (and therefore deliver water to the boiler). I may not of caught it but I wasn't clear if the elements that are "blowing up" are on the boiler that is being taken off-line or on the one remaining on-line. Sadly I find some spec boilers for ultra-pure steam needs to be operated with reverse osmosis or deionized water with no chemical treatment. I have 40+ years of experience in a hospital setting and some degree of experience with boilers and water chemistry. I am also going to strongly recommend a water chemistry test. I will definitely post to this when we discover the cause. What if there is a neutral and it is tied to ground.? Thank you all again. It is a delta heater configuration, but I do not know if the feeds have a neutral or not coming from a wye source. I tend to think there is something happening between ground and the phases, but we have yet to discover that. I tend to believe there is an issue with the overall system not the generators specifically and that is what I'm trying to get our techs to discover. The water level control is via a Warrick control board and the elements are controlled via standard contactors. We have them in use elsewhere and we service them with our medical equipment in many places. I can tell you there is nothing special about it. I did mention today in a thread above it is a CES Chromalox generator, but the design is considered proprietary. We have had some "fires" lately and this is only one of them. You are all very kind to even give this thought.

We are currently (no pun intended) working with the facility to verify wire sizes feeding the generators, but I still can't intuitively say that this would cause enough of an increase to blow the fuses and elements since the system with two generators runs problem free when it is running.Īny insights or thoughts would be greatly appreciated.
Fuse on steam generator#
It would seem that only a surge in voltage could cause this, but removing the other generator from the circuit should not cause such an increase in voltage as to cause these failures. The failures only occur when a unit is taken off line, but not every time. When two are running normally there is no issue.ġ) The voltage at each heater phase to phase is within tolerance of +- 10% (It's actually closer to 5%)Ģ) The operating current at each phase of each element has been verified to be correct when operating normally.ģ) The proper heaters are installed for this application.Ĥ) There is no pattern as to which element heater or fuse will fail.ĥ) We have not been able to re-create the failure at will in order to capture possible voltage and current anomalies.
Only two generators are on at any one time as they are sequenced as the load requirement varies and there is a third for redundancy.įrom the time they were installed, when one of the two running generators is taken off line to start the other (the third one not on), fuses and heater elements will randomly blow on the one still on line. There are 4 - 45 KW heaters and each heater has two elements. Each generator has 24 - 80 amp fuses to protect the elements. I have a field situation where our customer has 3 - 180kw steam generators, 208V 3ph connected to their service. I hope I can get some insight as to what might be happening here.Īs an EE it would seem that this is pretty straight forward, but nothing is making sense. Hello! I am new to the forum, so please bear with me.
