IRSH type ultra-low NOx regenerative burner

basic information

● Burner Structure and Principle It consists of an air register, two gas nozzles, a pilot burner, and a heat storage chamber. The combustion air is heat exchanged by the heat storage material (alumina balls) filled in the heat storage chamber and is ejected into the furnace at high speed from the air register nozzle with high-temperature air. When the furnace temperature is low, the fuel gas is ejected from the high-temperature air supply port of the air register through the primary gas nozzle. When the furnace temperature reaches above the ignition temperature, the gas supply from the primary gas nozzle is stopped, and gas is ejected from the secondary gas nozzle opened in the furnace, forming a recirculation flow and enabling slow combustion, significantly suppressing NOx emissions. This is a direct injection type burner for fuel within the furnace. ◆ Features - High-temperature, high-efficiency waste heat recovery ⇒ High specific unit values can be achieved. - Improvement of temperature distribution in the furnace due to high-temperature air combustion ⇒ High-quality products can be obtained. - Compact waste heat recovery system structure ⇒ Achieved by integrating the heat storage medium and the burner. - Reduction of NOx through flame temperature suppression combustion ⇒ NOx can be significantly reduced. - Possibility of compacting the furnace ⇒ Improved uniform heating and heating capacity. - Easy installation in existing furnaces ⇒ Can be installed in various industrial furnaces.
