The cooler is greater than 6" ID.
I was thinking that perhaps U-1(c)(2)(c) would apply since the cooler is required for the pump to operate. That would seem to satisfy the "integral part or component" phrase. The design requirements for the cooler are "derived" from the...
Our seal water coolers for the boiler circulating water pumps (BWCP) take their seal water supply from the suction of the BWCP. The BWCP has suction and discharge isolation valves and the seal water take off is between the suction isolation valve and the pump suction.

The unit is a 2950 psig utility boiler. I was going to use two isolation valves between the boiler and the chemical pump, but I don't think it could be considered an...
I'm attempting to understand a problem we had several weeks ago. I'm a mechanical engineer, so I probably don't have some of the terminology straight either.
We had several failures in the circuit breakers on equipment fed from our 5B 480V bus during a startup on our power plant. In one of...
I need to inject some chemicals into my boiler and have found an existing nozzle on the lower waterwall header. The nozzle is a dead leg with a "grayloc" blind hub on it which we use for cleaning the boiler. There are no valves between the header and the grayloc.
The chemicals will be...
