HedgeBird Posted March 29, 2012 Share Posted March 29, 2012 Howdy, I found a used boiler on auction that I am considering making an offer on. Steam boilers are not exactly my forte and I would appreciate any insight or suggestions from folks that might be more familiar with steam appliances. First off, here is the equipment I am looking to power with steam: - 300 Gallon Mashtun - pipe-in-pipe heat exchanger with 60+GPM circulator pump (10BLL) - 150 Gallon Plated Pot Still - fully-jacketed (5BBL) possible later expansion - 300 Gallon Stripping Still, or smaller continous sripping still Working under the assumption that I need 50,000 BTU per 1BBL of boiling capacity I need about 750,000 BTU.. The used unit I found is a 20HP (I beleive thats about 700,000 BTU) Hurst natural gas boiler bought new in 2004 and used for 3 years. Thats a bit shy of my estimate, but I am also looking at pre-heating mash water via the still condensor, or an in-line water heater, so perhaps thats not a big deal.. Obviously thought I want to be able to run both the still and mush tun at the same time.. I guese my questions would be: I understand its suggested to get one boiler to run everything and not dedicated boilers for each piece of equipment. Would those folks currently using steam agree with this? Is this unit large enought the have reasonable boil times? Is it possible to oversize the boiler? Is anyone familiar with this brand (Hurst) Based on the description provided, how much would a reasonable offer on this unit be? What would a great deal be?
