The soot and scale problems - Danfoss Heating

Figure 1 shows a water or superheater tube with soot at the outside of the tube and scale at the inside. In a water tube boiler the hot combustion gases pass a bank of tubes at the outside and release their energy to the water or steam flowing inside the tube. Figure 2 shows a fire tube with soot inside the tube.
