Compact Construction
The Cannon Feedwater Heater is a compact and durable box-type unit constructed to rugged boiler standards. This is not a disposable unit like many other designs, and will last as long as your boiler.
Rigid Steel Construction
The rigid steel frame is built to support the tube core, removable panels, the inlet and outlet transition and a stack of reasonable height. The frame is designed so that the unit can be supported overhead, avoiding any undue structural loads on your boiler outlet
Performance
Cannon's high-performance Feedwater Heater will extract heat from your boiler stack gases. This heat is then returned directly to the water feeding the boiler, considerably reducing your fuel costs. Our ASME feedwater heater core features extended surface finned tube elements.
Removable Panels
The Feedwater Heater has removable panels on each side and one end for easy inspection and cleaning, if necessary. All four sides of the unit are insulated with panel-type construction and feature a stainless steel interior for added corrosion resistance. |

• Tubes do not have welds in the gas stream, (welds are a potential place for corrosion to start)
• Tubes are lightweight, 1" OD
• Tubes have metallurgical bond to the fins by nickel brazed fin attachments.
• Tubes are attached to headers with compression fittings, easing repairs and eliminating the need for boiler inspector costs.
• Various tube and fin material combinations are possible for superior heat transfer and fouling/corrosion resistance.
• Tubes, fins, and fin count are tailored to customer's fuel type and operation conditions.
• Headers are manufactured from heavy wall pipe, and are located outside the gas stream.
• All materials can be individually upgraded to more corrosion resistant grades.
• Side panels and header panel have fiberglass insulation seal welded between steel layers.
