  2. Davited front doors allow for total access to the return tubes without interference of baffles or inner doors.
  3. To assure ease of opening and closing, front and rear doors utilize studs with lugs and brass nuts.
  4. Customers have a choice of burner manufacturers to gain the most efficient operation. Standard burners are specifically matched with the pressure vessel for complete, efficient cobustion. Burners are available in either gas or oil, or in a combination of gas and oil using either air or pressure atomization of the oil.
  5. Air louver linkage and setting visible for ease of mointoring adjustment and cleaning.
  6. Control panel - burner, skid or boiler mounted for ease of installation and maintenance.
  7. Control circuit junction box with terminal strip with skid or burner-mounted control panel to permit ease of checkout of individual controls.

  9. Structural steel skid-type base. Supports and protects burner.
  10. Location of large diameter furnace in boottom third of the boiler proivides for complete combustion and maximum heat transfer while being in contact with coolest boiler water.
  11. Furnaces for Section I (high pressure boilers) 24" diameter and larger are of Morison corrugation design.
  12. Front/rear door gaskets are made of ceramic fiber for long life.
  13. Roller-bearing supported davit makes possible a reduced opening space and can be arranged for left or right hand opening.
  14. Two-inch mineral fiber insulation with 8-lb. density contivutes to jacket support and reduced sheel heat loss.
  15. 22-gauge galvanized/phosphate coated steel jacket is painted with a hard enamel finish.
