  • 3 pass firetube boiler design

    A 3-pass firetube boiler design consists of three sets of horizontal tubes, with the stack outlet located on the rear of the boiler. A downdraft design keeps the cooler water from having an effect on the hot surfaces within the boiler. Generally speaking, a boiler with more passes provides more opportunities for hot gasses to transfer heat to
