I didn't think about you using anything other than a pressure boiler. The only nonpressure gasification boiler I know of is the garn and I wouldn't think of going with anything that wasn't gasification because of the amount of wood you are talking. If you go with a non pressure boiler then going nonpressure would be ok. No sence using a heat ex if you don't have to. But remember that chemicals are very expensive for the large gals you are talking.Frozen Canuck said:leaddog; ok, if I go the pressurized route does that limit my boiler choices to only those designed to operate under pressure? Could I install some sort of motorized valve between boiler & storage that would allow any boiler to operate in the system??
Just a side note for you (math majors) how much force is involved in a vessel 10,000 gal - 15,000 gal at 30 psi? Hopefully not as much as my paranoid mind just imagined! :bug: :bug: :bug:
I don't see where you would have any problem with pressure as the only place you would build high pressure would be in a overheat situation and I can't forsee you overheating 10000gals.
