Built-in accordance with the ASME Code, the wet back design has proven to give much longer useful life cycles than dry back boilers.
Each unit is tested and inspected and registered with the National Board of Boiler and Pressure Vessel Inspectors.
Hurst Boiler utilizes state of the art computer design techniques in every boiler. This accounts for accurate calculations of construction materials and optimum utilization of the boiler”s performance criteria.
The Series 500 is designed for optimum fuel efficiency and has proven in certified tests to meet, and often exceed, the efficiencies of four-pass boilers.
There are no refractory baffles to replace or maintain. Elimination of these will result in thousands of dollars in savings.
The wet back has independent tube sheets with uniform temperatures. Three and four pass dry back boilers have tube sheets with large temperature variations and this results in premature tube failure and cracks in the tube sheets.
Since there is no large refractory rear door, one man can easily remove the rear cover plates for access to the tubes. Front doors can be opened without removing burner components or controls.
With the computer-aided design, Hurst has made the wet back a space-saving workhorse without sacrificing the principle of 5 sq. ft. of heating surface per BHP.
Hurst uses name brand burner components with proven reliability. Every unit is boiler/burner compatible and tested at the factory prior to shipment.
