In the boiler operation process, under the action of wind power and combustion hot air flow fed into the boiler, impurity particles such as coal ash, unreacted limestone, limestone desulfurization reaction products and the like in the boiler are entrained by flue gas to move upwards in a hearth, so that the particles are in a fast fluidized state to form high-speed particle flow, large particles fall along the side wall of the hearth at different heights to form internal circulation of the materials, and the materials falling along the wall form wall flow, which is also the combustion characteristic of the circulating fluidized bed boiler. The decrease of the wall-attached flow causes scouring to the water-cooled wall, so that the heating surface of the membrane wall is seriously abraded.
The existing method aims at the problem of abrasion of a membrane wall of a boiler, and a transverse plate in transverse lap joint and a vertical plate in vertical lap joint are added on the membrane wall so as to control the gas-solid flow rate of an adherence wall in a hearth and reduce the abrasion of the hearth wall. In the process of rapid movement of material flow (wall flow), particles contained in the material flow impact the transverse plate for a long time, certain abrasion can be caused to the transverse plate, the existing wear-resistant plate is directly welded on the water-cooled wall, and replacement and maintenance are not easy.
