Steam Boilers

ddlong1286@yahoo.com

Hi all,

The company I work for is looking at replacing 2 Pacific Steel Boilers, M# 415-BG, 2100MBH, 47 HP. The control panel is M# NP240-G-E, 3500MBH.

My question is what would be a good replacement boiler? Do they make copper fin tube steamers?

The system has a vacuum pump, ITT M# 10VLR2-20-35.

Thanks
Don

is one brand, flexible steel tube types, not copper. Miura is another, more of a steam generator. I am not familiar with Pacific and what footprint they take up so am erring on the side of smaller boilers.

Firetube boilers such as Cleaver-Brooks can do well in the lower horsepowers but water tube boilers can tolerate higher pressures. I am not sure what pressure or process you are running.

Hi Brad,

Heating with radiators and one steam coil in ductwork. Low pressure, but not sure how low.

The boss mentioned copper fin tube, but had not heard of a manufacturer for this type boiler for steam.

Forgot Crane Co. was on tag with the Pacific name. Approx. 5 ft wide and 8 ft long.

Hi Don

I would go with Bryan at least as a place to start. They have a few models. I do imagine it is low pressure, not process like a laundry for example.

Get modulating fire if at all possible.

The steam coil unless it is cast iron (and assuming that the radiators are also cast iron) would dictate a fairly constant pressure operation and with traps. Not a "cycle" approach as you might on an average house.

If the coil is low-mass and is obviously heating air (also low mass hence volatile to changes), you can see how that zone may suffer unless the steam pressure is always available.
