Superior Firetube Boilers
Superior two-pass, three-pass or four-pass Scotch Marine (Fire Tube) boilers are available in dryback, wetback, steam or hot water versions; from 15 to 1,800 HP with pressures to 300 psig.
Superior Scotch Marine boilers are rated to 81% minimum efficiency. They are designed with davited rear doors for minimum maintenance and rugged construction for extra-long life. UL listed boiler/burner packages for firing gas, oil or a combination of both. They are factory tested and checked for optimum
operating efficiency.
The Superior Firebox is competitively priced, efficient and flexible three-pass boiler design allowing fuel flexibility for gas, oil, heavy oil, and combination gas/oil.
The firebox boiler is ASME Code constructed & stamped with the thickest boiler steel in the industry for 15 psi steam/30 water and registered with the National Board of Boiler Inspectors. The boiler includes unified refractory base floor, steel skids and lifting eyes.
Our compact, space saving vertical boilers provide exceptionally high efficiencies, lower fuel costs, and extremely rugged construction.
The compact, space saving vertical four-pass shock-proof design has no tubes to loosen or burn out. The Superior Vertical Tubeless Boiler allows convenient access to "eye high" burner and solid-state controls for trouble free operation. Factory assembled and fully automatic. UL and ASME CSD-1 approved. Simple and inexpensive to install.
The Superior Cheyenne combines extremely high efficiencies with the more rugged and durable construction for which Superior is known, for output capacities of between 3,800 – 11,400 MBH. (paragraph) The Cheyenne is available for firing natural gas or fuel oil with minimum turndown of 6:1 and 3:1 respectively. State-of-the-art Siemens LMV combustion controls are standard. Stainless steel tubing in condensing section and rifled tubes in the second pass maximize heat transfer and condensate flow. Large waterside volume eliminates minimum flow requirement.
