  • What Is Boiler Combustion? (with pictures)

    2019-8-4 · The combustion area of a boiler normally has tubes containing water and steam passing through an open box that may contain burners and controls. Tube design can improve efficiency, by using multi-pass systems. Water tubes entering the boiler may first pass through the flue gas zone, which takes some of waste heat and preheats the water.
