The present invention relates to a pellet boiler including: a main body in which a supply pipe provided for water supply is formed on an upper portion and a discharge pipe provided for water discharge is formed on a lower portion, a first chamber formed on an end portion on one inner side, a rostol disposed on an upper portion of the first chamber to form a second chamber, an exhaust pipe formed to communicate with one side of the second chamber, a plurality of guide pipe ducts formed to communicate with the first chamber for combustion gas guide, a plurality of heat exchange pipes provided for a combustion gas in the first chamber to be guided to the second chamber are provided, and a supply water storage space is provided; an air circulation portion provided with a third chamber disposed on a front surface portion of the main body, is formed to communicate with the plurality of heat exchange pipes, and guides the combustion gas stored in the first chamber to the second chamber; a pellet combustion device coupled with a lower portion of the air circulation portion provided for pellet combustion; a pellet injection pipe disposed to penetrate the air circulation portion and the pellet combustion device; and a cover coupled to close the third chamber of the air circulation portion. According to the present invention, the pellet combustion device on which a plurality of blowing devices are mounted is provided to be coupled with a front surface of the main body for heat exchange, thus the inconvenience of the related art having to couple a pellet combustion device with a heat exchanger can be addressed. Also, the high-temperature combustion gas generated as a result of pellet combustion is subjected to rapid circulation by a blowing device unit, thus improving the efficiency for heat exchange. In addition, a water jacket is formed on the pellet combustion device, thus preventing the result of temperature decline as a result of the interactions between the low temperature of the outside air and the inside air. |
