PROBLEM TO BE SOLVED: To provide a soot removing method for an independent type burning and smoking furnace for burning the soot jetted from a small hole of a damper completely when smoking to prevent it from becoming cause of air pollution. SOLUTION: Since a filter 13 made of a refractory material for letting exhaust gas containing the soot generated when smoking pass through it is provided in a bypass 10 of a main passage for exhaust gas and opening and closing devices are separately provided in the main passage and the bypass, the soot containing large particles unable to be easily burned is caught in the filter when the exhaust gas passes through the filter by closing the main passage when smoking to prevent the soot from being emitted into the atmosphere, and a part of combustion gas having high temperature at burning time passes through the filter to burn the soot caught in it so that this independent type burning and smoking furnace can be almost indefinitely used owing to its self-cleaning action.
