PROBLEM TO BE SOLVED: To provide a water-cooled wall structure for a stoker type incinerator that can improve the durability of a furnace wall in a high heat load region and effectively use heat energy generated from incineration. SOLUTION: The water-cooled wall structure, which is for a stoker type incinerator 10 for firing waste 30 moved on a fire grate 11 as supplying air from primary air inlets 12 positioned under the fire grate 11 and secondary air inlets 16 positioned in a furnace wall over the waste, arranges water pipes 26 at least in a high heat load region of a furnace wall positioned under the secondary air inlets 16 (a furnace wall around a feeder 13), extends the water pipes 26 to the high heat load region from a downstream end of the fire grate 11, and preferably sets an independent upper header of the water pipes 26 to form an independent circuit of a heat absorbing medium.
