  • Flue-gas stack - Wikipedia

    Flue-gas stack. A flue-gas stack, also known as a smoke stack, chimney stack or simply as a stack, is a type of chimney, a vertical pipe, channel or similar structure through which combustion product gases called flue gases are exhausted to the outside air. Flue gases are produced when coal, oil, natural gas, wood or any other fuel is combusted

  • 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
