Ohio Special Steam Boiler

  • Up to 82% Efficiency

The Sellers immersion fired Ohio Special steam boiler meets Ohio regulation for unattended boilers.

The boiler is a horizontal, single pass, firetube boiler designed to burn natural gas. The unique burner assembly delivers pre-mixed air and gas through multiple nozzles. The air-gas mixture is ignited as it exits each flame retaining nozzle at high velocity The resulting flames are long and small in diameter. The flame from each of these nozzles is directed into a 2″ O.D. tube that is completely immersed in liquid. There is a separate tube for each flame with the same amount of heat going into each tube. These small diameter flames burn in the first half of the tube lengths. Therefore, the “fire shines“ on half of the heating surface in the single pass boiler — 50% of the total heating surface is radiant heating surface.
