Apache - 2 Pass Dry Back

1. Single source responsibility: Apache boiler/ burner units are covered by Superior's warranty, effective for 18 months from shipment or one year from date of start-up. See warranty for complete details.
2. Front doors allow 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 manufactures to gain the most efficient operation.
5. Standard burners are specifically matched with the pressure vessel for complete, efficient combution. 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.
6. Air louvers and linkage settings have been positioned for the optimum ease of monitoring and adjustment.
7. At your option, the control panel can be burner mounted, skid mountd, or mounted on the side of the boiler for ease of maintenance and access.
8. A control circuit junction box complete with terminal strip is standard on all Apache boilers with a burner mounted, or skid mounted control panel. This junction box and strip allow the easy check-out of individual controls.
9. Factory-installed gas train is equipped with main gas pressure regulator. Standard gas trains comply with UL requirements and can be modified to meet IRI, FM, NFPA-8501 and oter codes.
10. Structural steel skid-type base, supports and protects burner.
11. Location of large diameter furnace in bottom third of the boiler provides fot complete combution and maximum heat transfer while being in contact with coolest boiler water.
12. Furnance for Section I (high pressure boilers)24" diameter (400 sq. ft.) and larger are of a Morison corrugation design.
13. Front/rear door gaskets are made of ceramic fiber for long life.
14. Roller-bearing supported rear door davit makes possible a reduced opening space and can be arranged for left or right hand opening.
15. Two-inch fiber insulation with 8-lb density contributes to jacket support and reduced shell heat loss.
16. 22-gauge coated steel jacket is painted with a hard enamel finish.
17. Turbulators are standard equipment in the 2 1/2" O.D. tubes to provide efficiencies of 80% or greater.
18. Front smokebox and doors are lined with ceramic fiber blanket.
