| 摘要 |
The present invention relates to a combustor comprising: an outer case having an accommodating space formed therein; an inner case provided in the accommodating space of the outer case and having an air injection port communicating with one side thereof; a combustion furnace provided inside the inner case so as to make the fuel fed therein combust; a grate provided, at the lower side of the combustion furnace, in a state in which the upper end thereof is eccentric, so as to stir the fuel and the byproducts of combustion when rotating; and a driving module for rotationally driving the grate. According to the present invention, since the eccentrically rotating grate stirs solid fuel, such as wood pellets, and ash so as to allow the smooth discharge of ash and inflow of air, the discharge of the byproducts of combustion and combustion efficiency can be increased, and clinkers generated when impurities of the fuel are hardened while being melted and fixed during combustion can be minimized. |
