I ran into a working rice coal burning steam boiler in Brattleboro Vt.

Its a steel  National Radiator Company  It has the main name plate stamped into

it with the Big  "H"  symbol  Relief valve cap. 5360 lbs /hr  and then it has the

letters - HSB  17271               Boiler Number AC6015            S/N 8334

does any one know what the HSB stands for? Also what that means for the

number after it of 17271?



Still looking to find out what the letters HSB 17271 mean.

    My guess???

    My guess is the big "H" somehow ties back to Hoffman and "HSB" Hoffman Steam Boilers or Hoffman Speciality Boiler (Products or Division)??? I did find this:

     the Hartford Steam Boiler Inspection and Insurance Co. (HSB) and worked in the Codes and Standards (C&S) Group in Hartford, Conn.

    HSB

    It probably is : the Hartford Steam Boiler Inspection and Insurance Co. (HSB) and worked in the Codes and Standards (C&S) Group in Hartford, Conn.  The numbers are probably a product number.

    The History of Hartford Steam Boiler . The Hartford Steam Boiler Inspection and Insurance Company was founded on June 30, 1866. Our first president considered HSB as THE JOHNSTON BOILER An Integral Part ofAmerican History Since 1 864 COMPANY STORY , — h. .. Realizing that here, lumber was king, IN 1864 JOHN WATT JOHNSTON SBS – Scandinavian Boiler Service was founded in Florida, USA in 1995. Today it is a global marine service and repair organization.
