The present invention relates to a firewood boiler comprising: a housing including, on a front surface part, a door capable of being opened and closed; a fire box arranged to be able to load firewood inside housing; an inlet formed on the lower part of the fire box to introduce combustion heat generated inside the fire box during the combustion of the firewood; a discharge pipe connected to the inlet to discharge, to the outside, the combustion heat having gone through the inlet; and a heat exchange member arranged at one side of the discharge pipe to warm water using the combustion heat going out through the discharge pipe, wherein the warmed water is supplied to the outside through a hot-water pipe or a heating-water pipe. Included is an air supply member for supplying air, which is introduced through an air blowing pipe, from the upper part, middle part and lower part of the fire box, wherein the air supply member is composed of a dual wall having a predetermined space formed inside by separating the fire box from the door, has the air blowing pipe connected to the outer wall of a front surface to introduce outer air, and has multiple nozzles formed on the inner wall of a rear surface in contact with the fire box to be spaced at predetermined intervals on the upper part, the middle part and the lower part. According to the present invention, wood vinegar or dregs remaining after combustion, which fall down to the lower part of the fire box during the combustion of the firewood, are prevented from clogging the nozzles via the structure of forming, on the front surface of the fire box, the multiple nozzles for supplying outer air into the fire box, thereby facilitating the combustion of the firewood. |
