dpc,
I agree with you both. This facility has a majority of fused disconnects and very few breakers for motor protection, so I think they were trying to shoot me a line of BS when they said it was against code. This place is a little old school and stuck in their ways and they just don't...
I am doing a new installation of some switchgear. Our current standard voltage at my facility is 575 V 3 Phase. The design for the motor controls is to have a breaker and not a fused disconnect. I was told that this is against code. My source said that this application is OK for 480 but not...
Thanks for all the help that I have recieved. With the help of your post I have calculated all my measurements. Now I have to incorporate my calculations.
Thanks again.
Thanks for the replies. They were a big help. I have found calculations for the velocity and have figured that out. I am working on a mass flow calculation now and the number I am coming up with is a little to high in my opinion. I am still working on it and will eventually get it. But I...
I am trying to figure out how much air flow is going through a square duct. I have airfoils in line and measuring differential pressure across them. I have the range of the transmitter but don't know how many inches of differential is equivilant to lbs/hr. I have tried to find venturi...
Thanks rmw for respnding to this forum. What I mean by bark air wide open is that the dampener coming off the fd fan is operating at 100% open. The type of grates are traveling grates. It is a CE four corner burner system.
I have a controls issue with a bark and gas fired boiler. I new at this so I need a little help. Our operators are running the boiler with bark air wide open at all times. I was given the assignment to redesign that system. I've trying to find control schemes on the web and have not had any...
