Zhonghe After-sales Tips No.1 | SR Series Burners Guide (Part 2) SR2 Burner Structure & Functions

Key parts: flame shroud, axial/swirl air ducts, fuel & central channels.

• Shroud: Concentrates flame to boost coal burnout

• Axial air: Encircles flame and absorbs high-temp secondary air

• Swirl air: Fully mixes fuel and air for thorough combustion

• Central air: Stabilizes flame, prevents nozzle blockage

• Coal/gas channels: Convey fuels; improper airflow leads to clogging or delayed combustion

Operating Principle

Coal/gas ejects at set angles. Swirl air mixes with fuel, then combines with axial air to freely adjust flame shape. Central air eliminates residual incomplete combustion gas for full fuel burnout.
