PROBLEM TO BE SOLVED: To provide a liquid waste disposal burner with excellent endurance capable of disposing liquid waste in which sludge is mixed without problems. SOLUTION: The liquid waste disposal burner is provided with a mixer 7 mixing the liquid waste with air, a burner pipe 3 extending from the mixer 7 toward the inside of a furnace, and an outer pipe 5 extending along the outside of the burner pipe 3. A width of a flow path in the mixer 7 and the burner pipe 3 is 5 mm or over. A space 17 which cooling airflow is flowed through is formed between an inner periphery of the outer pipe 5 and an outer periphery of the burner pipe 3. Gas and liquid can be mixed in good condition and mixture of the gas and liquid can be discharged at a pressure and a velocity nearly equal to those of a nozzle by getting a diameter of the burner pipe 3 to be 5 mm or over. As a cooling means for the burner pipe 3 is provided, the liquid waste remaining in the burner is not carbonized and the burner pipe is free from oxidation corrosion or the like due to the remaining liquid waste.
