PROBLEM TO BE SOLVED: To provide a woody pellet combustion device capable of improving a combustion state of woody pellet by suppressing accumulation of ash and generation of clinker on a combustion section. SOLUTION: In a pellet stove 10, the woody pellet 14 is conveyed by an upper screw 20 and a lower screw 22, and discharged onto a grate 32 from an opening 70A of a screw case 70, so that the woody pellet 14 is burned on the grate 32. Here, a left end of a screw blade 74 is disposed at a right side with respect to the opening 70A of the screw case 70. As pressing force to the woody pellet 14 on the grate 32 by the woody pellet 14 discharged from the opening 70A of the screw case 70 is increased, the accumulation of ash and the generation of clinker on the grate 32 can be suppressed, and the combustion state of the woody pellet 14 can be improved.
