Standard Features
Durability
Built in accordance with the ASME Code, the wet
back design has proven to give much longer useful life cycles than dry back
boilers.
Quality
Each unit is tested and
inspected and registered with the National Board of Boiler and Pressure
Vessel Inspectors.
Design
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.
Efficiency
The Euro Series is designed for optimum fuel efficiency and has
proven in certified tests to meet, and often exceed, the efficiencies of four-pass
boilers.
Low Maintenance
There are no refractory baffles to replace or maintain. Elimination
of these will result in thousands of dollars in savings.
Tube Sheets
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.
Easy Access
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.
Compact
With 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.
Combustion
Hurst uses name brand burner components with proven reliability.
Every unit is boiler/burner compatible and tested at the factory prior to shipment.

Euro Series is a full wet-back radiant heat transfer area that promotes superior internal water circulation and rapid heat absorption. Separate reare tubesheets allow each pass pass of tubes to expand and contract at its own rate without tube-to-sheet stress. Tubes are mechanically rolled, flared and beaded, making any tube service a simple matter. The only refractory in this design is a rear plug which allows access to the furnace for inspection.
