Abstract
PURPOSE:To reduce NOX by a method wherein in the passage of combustion gas near the outlet of the radiation tube of a radiation tube heater is provided a waste heat collecting mechanism of a duplex pipe which is equipped with a function as a heat exchanger for producing tempered air and a waste gas recycling function. CONSTITUTION:The air 4 used for combustion is changed into tempered air while the air 4 for combustion is guided into the internal tube 5 of a recuperator (waste heat collector) 3 connected near the outlet of a radiation tube 1 which penetrates the wall of the heating furnace and is arranged in a U-form, is returned in a U-form along the bottom of an external tube and heated between high temperature inside fins 6e. This tempered air is guided to a burner 8 through a Venturi portion provided at the external tube 6, and in this case, part of the burnt waste gas is absorbed through penetrating holes 6c at the Venturi portion and is returned to the burner 8. Therefore, the burner 8 receives the tempered air and reflux waste gas, is burnt efficiently and the NOX in the waste gas is reduced.
