X-Series Single-Pass Fire Tube Boiler

Sellers Fire tube boilers were originally designed to solve the problems that are inherent to the traditional scotch marine boiler design. All firetube boilers distribute energy through a collection of water-backed tubes to enable heat transfer. The Sellers Boiler is innovative in how it distributes that energy at the point of combustion, rather than a turnaround chamber. Uniform application of combustion energy eliminates thermal shock and allows relief of any possible energy buildup in the vessel through a rear relief door, which is unique in the industry.

In a traditional Scotch Marine Boiler, by contrast, 100% of the combustion energy feeds into the furnace. Because of its design flaws, the scotch marine boiler still presents the risk of thermal shock, resulting in a myriad of associated issues that will ultimately require significant maintenance and loss of operation time.
