They are specking out a johnson firetube boiler for the new biomass plant being built this spring.(25,000 lb. hr. boilker) I do not know anything about Johnson boilers or firetubes for that matter, we have all watertube. How will cleaning a firetube boiler be as compared to a watertube? We will be burning the gas from the wood chips so I assume it will be very clean. Is punching the tubes on such a unit difficult? We have a air driven tube cleaner. How about the reliability/durability of the Johnson boiler? any Pros or Cons? Thanks.
