<p>Disclosed is a boiler. The disclosed boiler comprises: a combustion chamber in which fuel is combusted; a connection pipe communicating with the combustion chamber, and allowing combustion gas and ashes generated when the fuel is combusted in the combustion chamber to flow therein; and an ash tray on which the ashes flowing along the connection pipe are accumulated. The ash tray includes: an ash accumulation panel on which the ashes are accumulated; an outdoor air flow hole formed to penetrate the ash accumulation panel so that outdoor air can be supplied to the ashes accumulated on the ash accumulation panel; and a support panel supporting the ash accumulation panel to be positioned at a certain height from an installation surface, wherein the support panel blocks all sides of the lower space of the ash accumulation panel, so the outdoor air flowing into the lower side of the ash accumulation panel can flow to the upper side of the ash accumulation panel through the outdoor air flow hole. The disclosed boiler includes the ash tray having the ash accumulation panel, the outdoor air flow hole, and the support panel which blocks all of the sides of the lower space of the ash accumulation panel, so the outdoor air flowing into the lower side of the ash accumulation panel through an air flow hole can flow into the upper space of the ash accumulation panel through the outdoor air flow hole without leakage to the outside of the ash tray, thereby combusting the ashes completely by combusting the ashes in the ash tray again, wherein the ashes are accumulated on the ash accumulation panel after flowing through the connection pipe when incompletely combusted in the combustion chamber.</p> |
