The specific embodiment

As Fig. 1, Fig. 2, shown in Figure 3, the airtight container that body of heater is welded by base plate 1, four blocks of coaming plates 7 and upper cover plate 13, two parallel dividing

plates

5,12 of welding are divided into preheating cabinet 20,

middle incubator

21 and 22 3 water tanks of high-temperature cabinet with inner chamber in the body of heater, and the through hole on the dividing

plate

5,12 flows the water of three casees.Water inlet pipe 10 is installed in the top of preheating cabinet 20, the middle and lower part of incubator 21 and high-temperature cabinet 22 during outlet pipe 23 is installed in respectively.

As Fig. 1, shown in Figure 3, burner hearth 24 is installed in the bottom of high-temperature cabinet 23, comprise that the water tank bottom plate 15 of two hearth walls 18 and fire bars 17 high-temperature cabinet bottoms is located in the upper end of hearth wall 18, some smoke pipes 6 of the vertical welding in water tank bottom plate 15 upper ends, smoke pipe 6 lower ends and burner hearth connect, and upper end and 9 welding of last smoke chamber also connect, some horizontal water tubes 16 of lower horizontal welding of water tank bottom plate 15, tube wall exposes in burner hearth, and two ends and high-temperature cabinet connect.
