Abstract

A bottom ash discharging device for coal-fired boiler comprises a clinker case (9), installed between the bottom ash hopper outlet (4) of the coal-fired boiler and the bottom ash conveyer(l), and impact bar (2), composed of a plurality of heat-resistant metal rods supporting inside the clinker case (9), and a clinker crusher (3), installed above the impact bar (2), for crushing the clinker, wherein, further comprises a guiding device that limiting the clinker to drop into the clinker crushing area of the clinker crusher(3), installed between the bottom ash hopper outlet (4) and the clinker erusher(3), the low ends of the guiding plate is closer than the baffle plate to the clinker crushing body (7), and the bottom edges of the guiding plate are lower than the top edge of the baffle plate. This invention is to solve the technical problems that the clinker dropping from the bottom ash hopper outlet to the rear area of the clinker crusher so as to affect its normal working, and the invention can especially apply for discharging clinker from various coal-fired boilers.
