Robust Pressure Vessel

The Fulton Classic offers a cutting-edge design backed by industry-leading simplicity. For instance, the furnace or pressure vessel demonstrates remarkable simplicity by being a pipe within a pipe.

The top mounted burner delivers a spinning cyclonic flame down the center furnace chamber. This same flame is sent back up the exterior of the vessel. While this design is simple, it delivers exceptionally even heating bolstered by a forgiving and durable design.

The Fulton Classic Combustion Process

The Fulton Classic delivers unparalleled durability and reliability for a virtually endless list of applications. Regardless of your needs, the Fulton Classic's combustion process is the same.

  1. Air is pulled into the power burner where it delivers optimum combustion after being mixed with fuel.

  2. After the ignition assembly ignites the fuel/air mixture, the first pass is completed by sending a spinning cyclonic flame down the length of the chamber.

  3. The flame retainer rings increase occupancy time of the flue gas, which improves heat transfer.

  4. Flue gases are sent back from the base of the chamber and return over the heat convection fins surrounding the entire water jacket. This process constitutes the second pass and functions to transfer additional heat to the water in the vessel.

  5. All flue gases are collected at the top portion of the boiler and seamlessly expelled through the flue outlet.
