Method and apparatus for removing dust from boiler radiation heat transfer surface in stoker-type incinerator with boiler

摘要

PROBLEM TO BE SOLVED: To reduce the amount of power generation due to the deterioration of the heat transfer performance of the boiler radiation heat transfer surface, prolong the life of the boiler by reducing the corrosion of the superheater, reduce maintenance costs, and reduce the maintenance and management costs by reducing the scale and frequency of furnace cleaning. Reduce the damage inside the furnace due to the fall of grown dust. SOLUTION: This is a method 1 for removing dust from a boiler radiation heat transfer surface in a waste treatment furnace 3 provided with a boiler 2, wherein an inner surface is an outer position of a water pipe wall 18 having a radiation heat transfer surface of the boiler 2. The water pipe wall 18 itself is vibrated by applying a striking force to the water pipe wall 18 by a plurality of hitting devices 20 disposed in the apparatus, and dust attached to the inner surface of the water pipe wall 18 forming the boiler radiation heat transfer surface is removed. I do. [Selection diagram] Fig. 1
