Firetube Boilers - National Board of Boiler and Pressure

This adversely affects boiler efficiency and can cause the tubes to overheat. Tube ends that are projecting beyond the tube sheet more than the Code allows can overheat and crack. If the tubes are attached to the tube sheet by welding, cracks in the tube ends can propagate to the tube sheet, and possibly run into the ligaments between the tubes.
