Description

Technical Field

[0001] The utility model relates to the technical field of fluidized bed furnace slag discharge, in particular to a fluidized bed furnace with a slag discharge port anti-blocking function. Background Art

[0002] During the incineration process of the drying kiln boiling furnace, some combustion products are mainly calcium oxide, which will form small particles and remain in the furnace. In addition to the combustion of combustibles, the remaining materials need to be discharged. Most of the bottom slag of the combustion products is discharged from the bottom of the boiling furnace along the slag discharge device, and a small part of the fine ash adheres to the furnace wall. Over time, a lot of fine ash adheres to the furnace wall to form block slag. These block bottom slag falls from the furnace wall and easily blocks the slag discharge port. When the slag discharge port is blocked, it can only be discharged manually. During the slag discharge process, the bottom slag is sprayed out, and there is a risk of scalding. Utility Model Content
