Function

Three pass fire tube boiler

Generally speaking, a boiler with more passes provides more opportunities for hot gasses to transfer heat to the water in a boiler and operate more efficiently, however, boiler efficiency is highly affected by tube design, and not simply the number of passes. It is possible for a 3-pass boiler with a tube design (such as XID boiler tubes) that allows more heat transfer time to deliver the same or higher efficiency rating than a 4-pass boiler with standard tubes.

3 pass firetube boilers offer:

  • maximized heat transfer

  • minimal refractory

  • high steam/water storage

  • effective handling of wide load demands
