PROBLEM TO BE SOLVED: To suppress generation of nitrogen oxide of a thermal storage combustion equipment by communicating a fuel injection nozzle with a mixer of an oxidizer introducing outer cylinder for introducing a specific amount of an oxidizer and a fuel introducing inner cylinder provided in the outer cylinder, and communicating a long holelike air injection nozzle with a thermal storage chamber provided in the outer cylinder. SOLUTION: Long hole-like air injection nozzles 2 are provided at both sides of a fuel injection nozzle. The nozzle 1 is formed in an envelope range 8 indicated by a broken line of the nozzle 1. The nozzle 1 is constituted to communicate with a mixer 5 of an oxidizer introducing outer cylinder 3 for introducing 30% or more of a stoichiometric ratio of an oxidizer and a fuel introducing inner cylinder 4 provided in the outer cylinder 3. Further, the nozzle 2 is constituted to communication with a thermal storage chamber 6 provided in the cylinder 3. The nozzle 1 is constituted to communicate directly with a fuel introducing cylinder 7 and the nozzle 2 is constituted to communicate with the chamber 6 provided at an outer periphery of the cylinder 7. |
