CONSTRUCTION FEATURES:

  • Davited front doors and split/hinged rear doors that allow access to return tubes for ease in cleaning and maintenance.
  • Front smoke box and doors are lined with space-age ceramic fiber.
  • Large furnace with large diameter and sufficient length provides required furnace volume assuring complete combustion of fuel, especially for heavy oil. Furnace is of ring-reinforced type, providing a very rigid structure and additional heating surface from the stiffener rings.
  • 3-Pass design for optimum efficiency and economical operation.Burners are available in gas, light or heavy oil, and combustion; with air or steam combustion, and pressure atomization of the oil.
  • Structural steel skid base supports and aesthetically projects the boiler vessel and the burner.
  • Front and rear doors are held shut using studs with lugs and brass nuts for easy removal.
  • Wet-back design turnaround eliminates the need for refractory lining, baffles, gaskets and provides additional primary heating surface for increased efficiency.
  • Two inch thick 132 kg/cu cm density mineral wool insulation reduces heat loss through the shell surfaces.
  • Round smoke outlet requires only a stub shack for proper draft.
  • Stainless steel finish for shell, to provide aesthetics and durability.
  • Capacities from 60 to 1500 Bo. HP (940 to 23,500 kg/h).
  • Operating Pressure of up to 270 psig (18.63 Bars).
  • High efficiency, attaining thermal efficiency of up to 93% at MCR when firing heavy oil (based on LHV) 3 pass wet-back design combined with a generous heating surface of 5 sq/ft per BoHP. Wet back design eliminates heavy refractory at rear door reducing maintenance cost.
  • Highly efficient full modulation U.S. made Industrial Combustion Burner, air/steam atomized burner with 5:1 turn down, attains very high combustion efficiencies even at low loads.
  • Large heating surface and high efficiency burner, translates into large savings in fuel cost High quality fittings and components
