Detailed Description
Fig. 1 is a schematic structural diagram of an embodiment of the prior art. In the prior art, the furnace wall of the garbage incinerator comprises a side wall system consisting of a drying section side wall 7, a combustion section side wall 8, a burning section side wall 9 and a front side wall and a rear side wall which respectively correspond to a drying grate 4, a combustion grate 5 and a burning grate 6, and a hearth top wall system consisting of a front arch water-cooled wall 2 and a rear arch water-cooled wall 3. The side wall of the fire grate adopts a full heat insulation furnace wall or a full air cooling furnace wall.
