ASH CONVEYING SCREW FOR SOLID FUEL BOILERS

摘要

The present invention relates to an ash transfer screw for a solid fuel boiler. The ash transfer screw for a solid fuel boiler comprises: a driving transfer pipe shaft (100) on a horizontal line of which one side is connected to be operated to a driving unit to be supported; a driven pipe shaft (200) on the horizontal line of which the other side is coupled to and supported by a rear side of a boiler main body (1) of a rear end of a combustion chamber (3); a heat recovery screw pipe (300) connected to a gap between the driving transfer pipe shaft (100) and the driven pipe shaft (200); and a support transfer screw wing (400) supporting the heat recovery screw pipe (300) to prevent the heat recovery screw pipe from sagging downward.
