There is provided a boiler (1), constructed in such a manner that a primary combustion chamber (2) is formed at the center of the boiler (1) according to a primary water chamber (3) having an approximate cylindrical shape; a secondary water chamber (5) is formed, surrounding the primary water chamber (3), to form secondary combustion chamber (6); a guide plate (8) is set at the position where a heat source is injected from a burner (7) in the primary combustion chamber (2) to guide the heat source to a screw (9) having a plurality of veins (96) for guiding the heat source; and a plurality of guide plates (11) are formed having a predetermined interval on the outside wall of the primary water chamber constructing the secondary combustion chamber (6), the guide plates (11) being inclined downward. Therefore, heat transfer effect is maximized and fuel expense is reduced. |
