The present invention relates to a pellet boiler and, more specifically, to a pellet boiler comprising a flue (200) for combusting a pellet; a pellet supply device (300) for supplying a pellet to the flue; and a combustion chamber container (100) on the top of the flue (200) to heat water in a water pipe using heat caused by the combustion of a pellet. The combustion chamber container (100) comprises a lower container (110), an upper outer container (120), an upper inner container (130), and an upper intermediate container (140). A spirally coiled first water pipe (WP1) is arranged to be in touch with the inner circumference of the inner container (130). A spirally coiled second water pipe (WP2) is arranged to be in touch with the outer circumference of the inner container (130). A spirally coiled third water pipe (WP3) is arranged to be in touch with the inner circumference of the upper intermediate container (140). A spirally coiled fourth water pipe (WP4) is arranged to be in touch with the outer circumference of the upper intermediate container (140). A spirally coiled fifth water pipe (WP5) is arranged to be in touch with the inner circumference of the upper outer container (120). Low temperature water is supplied to the fifth water pipe (WP5). The first to fourth water pipes (WP1, WP2, WP3, WP4) are connected to each other through a branch pipe (B) of the fifth water pipe (WP5). The first to fourth water pipes (WP1, WP2, WP3, WP4) are connected to a head box (160) on the top of the inner container (130). |
