COMBUSTION EQUIPMENT

PURPOSE: To provide combustion equipment which can switch a fuel oil and a mixed oil automatically with the same unit to perform a combustion smoothly without expanding the scale of equipment. CONSTITUTION: In combustion equipment which is provided with a fuel oil path 5 to pressurize and supply a fuel oil to jetting pipes 8a and 8b of a burner 3 and a waste oil path 6 to pressurize and supply waste oil to a jetting pipe and gets the both mixed in the jetting pipe to be sprayed from spray nozzles 7a and 7b at the tip of the jetting pipe for combustion, the temperature and/or pressure of the waste oil is detected and when the values thereof are above prescribed values, the waste oil is mixed with the fuel oil to perform a combustion of a mixed oil. When they are below prescribed values, a combustion of the fuel oil is performed to burn the fuel oil alone.
