PURPOSE: A multi-functional boiler is provided to prevent air pollution by eliminating impurities, soot and smoke exhausted through an exhaust pipe. CONSTITUTION: A multi-functional boiler(100) comprises a combustion chamber(110) and a flue(120). The combustion chamber burns fuel. The fuel discharges combustion heat and combustion gas generated in the combustion chamber to outside. The flue is communicated with one side of the combustion chamber. The combustion heat and gas are inserted into the combustion chamber again, and then discharged. |
