PURPOSE: A multi-functional boiler device is provided to maximize the fuel efficiency and to prevent the damage of components by equally supplying flames and air to fuel. CONSTITUTION: A hole is formed in the center of rostol(15). An injection hole(40) is connected with an injection pipe(42) to form a guiding pipe(41) to guide flames of a burner(35) and a protrusion portion(42'). The protrusion portion is inserted to the upper part of a rostol hole. Many through holes(43) is formed in the protrusion portion to inject the flames in all directions. An upper heat exchange chamber(21) is connected through the upper part of the combustion chamber. A lower combustion chamber(22) having an exhaust pipe(23) is formed in the lower part of the combustion chamber. Exhaust gas is ventilated by connecting the upper heat exchange chamber with the lower combustion chamber through many vertical pipes(25). Thereby, the combustion efficiency is maximized.
