PURPOSE: A thermal storage burner is provided to prevent environmental pollution by minimizing the amount of NOx(nitrogen oxide) contained in exhaust gas of a thermal storage burner and to enhance thermal efficiency of a combustion furnace by preheating combustion air at a high temperature with the stored heat in a thermal storage body. CONSTITUTION: A primary air is mixed with fuel in a combustion container(60) to perform the primary combustion. A part of combustion gas thereof is mixed with secondary combustion air to perform the secondary combustion in a combustion nozzle. The primary combustion gas and secondary combustion air is mixed each other outside a burner for the third combustion. The exhaust gas re-circulates in the burner itself by mixing the primary combustion gas and the secondary air without mounting an additional recirculating pipe. Therefore, the environmental pollution is prevented by lowering the generation of NOx under the reference value with high-temperature combustion air. |
