Title: steam boiler for stuart triple
Post by: pip jones on December 21, 2010, 02:04:59 pm
can anyone tell me if there is a boiler made to suit the stuart triple. it must produce about 4lbs steam per hour at 150psi, and i am struggling to find something suitable. regards, pip jones.

pip....talk with mailto: mike@maccsteam.com   boilers....his largest boiler [6" horizontal] is listed as follows...I would suggest you simply confirm your intended engine as your specification requirement [4lbs steam per hour] is questionable .....Derek

thanks derek. the problem is i have been told that the triple will only run efficiently on 120-150psi, and the maccsteam boiler is only rated at 80psi. it will obviously run on this pressure, but not to its full potential. regards, pip
