3 pass firetube boiler design

4 pass firetube boiler design

A four-pass boiler design consists of four sets of horizontal tubes, with the stack outlet at the front of the vessel. A downdraft design keeps the cooler water from having an effect on the hot surfaces within the boiler. 4-pass boilers leverage natural draft operation which allows cool water to contact the hottest part of the boiler.
