For the type of three pass fire tube boiler, each set of tubes that hot combustion flue gas travels through before making a turn within the boiler, is considered a "pass." Three pass firetube boiler designed by Shengli Boiler consists of three sets of horizontal tubes, with the stack outlet located on the rear. A downdraft design keeps the cooler water from having an effect on the hot surfaces within the boiler.

 

In a word, a boiler with more passes provides more opportunities for hot gasses to transfer heat to the water in a boiler and operate more efficiently, at the same time, boiler efficiency is deeply affected by the tube design, and not simply the number of passes. It is possible for a three pass boiler with a tube design that allows more heat transfer time to deliver the same or higher efficiency rating than a four pass boiler with standard tubes.
