Introducing the New Hurst Series 250W Boiler

The WetBack Advantage
Dry backs boilers are subject to deteriorating rear refractory, leaking baffles, leaking door seals, and often found with a heat-stressed rear tube sheet. Fragile refractory baffling and door seals will require continuous monitoring, maintenance, and replacement, costing thousands of dollars in materials and specialized labor costs over the life of the boiler. In addition, broken baffles and leaking seals will short-circuit the boiler’s gas flow, causing high stack temperatures and lowering efficiency until repairs can be made. This can bring your production process to a costly halt.

All of those frustrating problems have been designed out of the Hurst Series 250W Wet back. It has a full wet back radiant heat transfer area that promotes superior internal water circulation and rapid heat absorption. The 250W’s 2-pass design allows the fire tubes to expand and contract at its own rate without tube-to-sheet stress. All fire tubes are mechanically rolled, flared and beaded, making any tube service a simple matter. The only rear refractory in this design is a manway plug which allows access to the furnace for service and annual inspection.

The Hurst 250 Series Boilers have been designed and developed specifically for the International Market, and engineered to fit easily in a 40-ft shipping container. The advanced design enables Hurst to provide a full wet-back scotch marine boiler with a larger furnace, and a lesser amount of technically enhanced tubes.
