PROBLEM TO BE SOLVED: To provide a mixed fuel combustion equipment effectively prevented from the overheat damage of a combustion chamber and the instability of combustion against the quality change of liquid fuel. SOLUTION: The mixed fuel combustion equipment is provided with the independent components of fuel feeding parts 9, 10 and 11 forming a mixed combustion region F of both of liquid fuel L and gas fuel G feeding the atomized liquid fuel L and the gas fuel G into a combustion chamber 2. Further, the equipment has combustion air jets 16 and 10 intensively feeding combustion air A2 and combustion air A1, required for combustion at the mixed combustion region F, into the mixed combustion region F inside the combustion chamber; and a cooling air jet 18 feeding cooling air A3, required for the cooling of the combustion chamber 2, into the combustion chamber 2 in a state suppressed from reaching the combustion region F than the combustion air A2 and the combustion air A1.
