Incinerator with anti-toppling fire barrier

The incinerator comprises an incinerator wall and the fire barrier, the section of the fire barrier is in a 7 shape, the side edge of the fire barrier is divided into a free side and a non-free side, the free side is provided with a first thickened end, and the non-free side is embedded into a lining of the incinerator wall; a base is arranged at the bottom of the fire barrier; the length direction of the base is parallel to the airflow direction; the non-free side of the fire barrier is embedded into the furnace wall, so that the binding force between the fire barrier and the furnace wall is increased; meanwhile, the length direction of the bottom-layer standard bricks is along the airflow direction, so that the anti-toppling capacity is enhanced while the pressure intensity of the supporting surface is reduced; and secondly, the end of the free side of the fire barrier is thickened, the supporting force is increased, the risk that the fire barrier topples over due to shaking and vibration in the hoisting an
