PROBLEM TO BE SOLVED: To make a combustion chamber small by supplying secondary air to the vicinity of a primary flame and shortening a secondary flame, and to suppress the occurrence of NOx, and besides to prevent the deformation or damage of the periphery of a burner head or the occurrence of reverse fire. SOLUTION: In combustion equipment which is equipped with a fuel supply pipe 13 for supplying fuel to an evaporating chamber 1 for evaporating liquid fuel, an air nozzle 8 for supplying primary air to the evaporating chamber 1, a burner head 4 having a flame hole 5 for jetting out mixed gas where evaporated fuel and primary air are mixed thereby forming a primary flame 6, an ignition plug 14 for igniting the mixed gas jetted out of the flame hole 5, a flame holding plate 15 around the primary flame 6, and a secondary air blowout port 12 which blows out the secondary air 10 circulated from the secondary air circulation port 9 to the vicinity of the primary flame 6, the whole of the secondary air blowout port 12 is positioned in a position under the top end of the flame holding plate 15.
