PROBLEM TO BE SOLVED: To keep the combustion state of a burner in stable condition, by precisely adjusting the air ratio (the ratio of the actual quantity of air to the logical quantity of air) required by the burner. SOLUTION: This is a combustion equipment which is provided with a fan 7 for ventilating air for combustion to a full primary premixing type of burner 3 through a ventilation flue 6, a tubular mixing chamber 9 for mixing the fuel supplied accompanying the ventilation of the fan 7 being connected to the suction part 8 of the fan 7, and a control means H for controlling the combustion of the burner 3. An air supply chamber 16, which inhales the air for combustion accompanying the ventilation of the fan 7 and supplies the air for combustion to an inlet 11 for combustion, is provided upstream in the flow direction of the air for combustion of the combustion air suction part 11 of the premixing part 9. A governor 10, which is installed in the fuel supply path 10 to supply fuel and keeps the fuel supply pressure down the installation place at set pressure, keeps the fuel supply pressure at the pressure within the air supply chamber 16.
