	18. Ceramic Fiber Blanket: Front and rear smokebox and doors are lined with space-age ceramic fiber blanket. 17. X-ID® Tube Design: 3 pass X-ID® tube design for optimum efficiency and economical operation. 16. Galvanized Coated Steel Jacket: A 500 degree Fahrenheit acrylic silicone based paint finish is applied to the 22-gauge phosphate galvanized coated steel jacket. 15. Insulation: Two inch 8-lb. density mineral fiber insulation with an R factor of .27 which reduces heat loss through the jacket and provides jacket support. 14. Lifting Eyes: Heavy steel lifting eyes for ease of handling. 13. Stack Outlet: Flanged round rear smoke outlet requires only a stub stack for proper draft. 12. Rear Doors: Split/hinged rear doors provide access to the rear tubesheet and third pass tube. 1. Single Source Responsibility: Superior Boiler Works, Inc. Seminole Boiler/Burner units are covered by Superior’s warranty* of 18 months from date of shipment or 1 year from date of startup. 11. Wetback Turnaround: Wetback turnaround eliminates the need for refractory lining, baffles, gaskets and provides additional primary heating surface for increased efficiency. Separate tube sheets allow for differences in expansion due to varying temperatures of the gasses. 10. Furnace: Large diameter furnace provides for complete combustion and maximum heat transfer. Furnaces for Section I (HIGH PRESSURE BOILERS) 24’’ diameter and larger are of the Morison corrugated design. 9. Boiler Skid: Structural steel skid-type base supports and protects burner. 8. Gas Train: Factory mounted and wired gas train complete with main gas pressure regulator. Standard gas trains comply with UL requirements. IRI or FM and other code requirements available upon request. 7. Boiler Junction Box: Control circuit junction box with terminal strips to permit checking individual control operations. 6. Burner Control Panel: Burner or boiler mounted for ease of operation and maintenance. 5. Air louver: Air louver, linkage and setting is visible for ease of monitoring, adjustment and cleaning. 4. Burner: Customer choice of single source of superior package or choice of burner manufacturers for efficient operation and ease of maintenance. Burners are specifically matched with the furnace diameter and length for complete/efficient combustion. Burners are available in gas or light or heavy oil and combination with air or pressure atomization of the oil, and Low NOx capabilities. 3. Studs, Washers and Brass Nuts: Front and rear doors are closed using studs with washers and brass nuts for ease of opening and closing. 2. Davited Doors: Davited doors allow for total access to the return tubes without interference of baffles or inner doors.

Waterside access is provided by (2) 3” x 4” handholes located in front tubesheet near the bottom of the shell in addition to (2) handholes on the bottom centerline. (1) 3” x 4” handhole or (1) 12” x 16” manway on the top centerline and (1) 3” x 4” handhole in the rear tubesheet.	All Superior Boiler Works Super Seminole Boiler/Burner units are manufactured to ASME code requirements with each unit inspected by a National Board of Boiler & Pressure Vessels registered inspector.	Demand 3/4” thick tubesheets and 9/l6” minimum tube hole ligament to decrease the possibilities of ligament cracks, warped and overheated tubesheet and better tube holding capabilities.

Full Front Tubesheet access is provided by split/davited doors. No electrical or fuel connections or linkage need be disconnected for access to the fireside. Front smokebox and doors are lined with ceramic fiber blanket.	Super Seminole’s 3-pass X-ID® design maintains gas velocities for effective heat transfer with moderate gas side pressure drops resulting in efficient gas to water heat transfer and reduced blower motor loads.	Hot water boilers reducing return nozzle provides increased return water velocity and aids natural internal water circulation.

Super Seminole’s Wetback turnaround eliminates refractory baffles and gaskets.	Steam boilers _ large disengaging area and dry plate (high pressure) or dry pan (low pressure) at the steam outlet assures high quality, dry steam.	Super Seminole Boiler/Burner units are factory firetested to check electrical components for proper operation and adjustment of the fuel/air ratio for smooth ignition and firing.

Superior Boiler Works, Inc. has been manufacturing Scotch Marine Boilers in Hutchinson, Kansas since 1940. The Seminole 3-Pass Wetbacks design was added to the Superior Boiler Works’ line of equipment in 1969 in response to a growing market demand for a full Wetback Firetube boiler. Many of the same unique maintenance features available on other Superior Boiler Works, Inc. Scotch Marine Boilers were incorporated into the Seminole design. In our continued efforts to improve the design and performance we have introduced our “Super” Seminole (XI-D) 3-pass boiler. The “Super” Seminole Line will offer incredible efficiencies that will be unparalleled.
