I. Core Technical Features
• Flexible heat supplementation through the regenerator, using natural gas, coal gas, or other energy sources. When CO concentration reaches about 6,000 mg/Nm³, the system maintains thermal balance without additional fuel. At 9–10×10³ mg/Nm³, the system can cover the energy required for SCR denitrification; above 10,000 mg/Nm³, steam can be generated.
• Strong adaptability to operating conditions: the system stably maintains the required temperature and residence time for oxidation, ensuring stable CO, VOCs, and NOx removal.
• Precise control with multi-dimensional regulation parameters, including combustion purification temperature, flue gas temperature, and combustible gas concentration, enabling accurate operator control.
• Excellent protection through a multi-module integrated heat recovery design, preventing thermal damage, corrosion, and clogging.
II. Process Flow
Process Flow Diagram of This Unit
Kiln flue gas sequentially passes through the indirect heat exchange module and the regenerative module, where it recovers heat and is preheated, before entering the combustion purification module for complete oxidation. The high-temperature flue gas then passes through the regenerative module again, delivering stored heat to the incoming low-temperature flue gas. When excess heat is available, a waste heat boiler can be added to recover the excess heat as steam for power generation or thermal use. The flue gas then enters the SCR denitrification module for NOx removal. After denitrification, the flue gas re-enters the indirect heat exchange module for further heat recovery. Finally, the purified flue gas is discharged after CO is utilized and VOCs, NOx, and other pollutants are removed.
