A boiler ash tray apparatus is provided to improve combustion efficiency by smoothly and uniformly distributing fuel through a distribution member arranged on an ash tray grille. A boiler ash tray apparatus comprises an ash tray grille(10) and a rotating unit(20). The ash tray grille has a plurality of support members(14) formed into shapes of screw bars which contact fuel in advance. The support members are formed in a frame(12). A distribution member is arranged on the support members so as to uniformly distribute fuel. The rotating unit is connected between the ash tray grille and a power transmission unit. The rotating unit includes a support rod(22) fixed at a fixing member(21) arranged at both sides of a bottom surface of the frame; a rotary shaft(24) corresponding to the support rod; and a pair of rotating members(25) arranged at the respective ends of the rotary shaft.
