FB-S Horizontal Firetube Steam Boiler

• High Efficiencies, High Performance
• Long Lasting Heat Exchanger Life

The FB-S is a traditional three-pass, wet-back horizontal firetube boiler. The first pass flows through the furnace from front to back. The furnace is corrugated to maximize efficiency while also minimizing thermal stress. Flue gasses then travel from the combustion furnace to the front chamber forming the second pass. For the third pass gases flow through tubes to the back of the boiler stack and out the exhaust vent, located conveniently in the back of the boiler. The second and third passes travel through heavy-duty seamless tubes.

The FB-S boiler has a liberal steam release area, making it an ideal choice for low pressure steam applications
