We are working on a project that will be taking a building off central steam plant and installing one new boiler and one used boiler and duplex boiler feed pump. The boilers are manufactured by Hurst Boiler. They are forced draft boilers. One is a 30 hp and the other is 40 hp. They will operate at approximately 8 psi.
We only have 84" from the concrete pad to the rafters in the basement. The steam outlet on the 30 hp boiler is 59" from the pad and the 40 hp boiler is 72" from pad to steam outlet. In order to make a header and have enough room to pipe into the top of the header, the header will be very low (maybe only 10" above the water line on the 40 hp boiler)
1.) Will that be enough room to prevent any problems?
2.) Do you see any problems with unequal water lines?
