AI Technical Summary
In the ash discharge system of a circulating fluidized bed boiler, the ash discharge pipe is prone to blockage due to incompletely burned coal particles or large foreign objects. Existing unblocking devices are inefficient and pose safety hazards.
A device for clearing blockages in a boiler ash discharge system was designed. It is a mechanized system consisting of a ash-poke rod and a power source. The ash-poke rod mechanically impacts the blockage, and the system is automated by combining a guide sleeve and a limiting component.
It improved the efficiency of unblocking, reduced the labor intensity and safety risks for operators, and ensured the smooth operation and safety of the slag discharge system.
