During industrial production, energy utilization, or combustion processes, gas mixtures (e.g., dust, acidic/alkaline gases, toxic/hazardous gases) with temperatures significantly above ambient levels are generated. If discharged directly without treatment, they can severely impact equipment, personnel, and the environment.
High-temperature flue gas treatment typically involves technologies and equipment such as waste heat recovery, cooling systems, and high-temperature dust removal, aimed at reducing pollutant emissions and recovering waste heat resources. It is widely used in the metallurgy, building materials, chemical industry, power generation, and incineration sectors.

It offers excellent high-temperature and corrosion resistance, making it suitable for flue gas dust collection in extreme operating conditions exceeding 200 °C.
