(I) Continuous Upgrading of Ultra-Low Emission Technologies
As global environmental protection standards continue to rise, ultra-low emission technologies for industrial chimneys have become a key focus of industry research and development. By 2026, novel materials-such as low-temperature catalysts and composite desulfurization agents-are expected to see widespread application; these materials enable highly efficient desulfurization and denitrification at lower temperatures, thereby reducing energy consumption and waste residue generation. For instance, the steel industry is adopting a "dual-tower series desulfurization + low-temperature SCR denitrification" technology combination, capable of meeting emission requirements of less than 35 mg/m³ for SO₂ and less than 50 mg/m³ for NOₓ. Meanwhile, the cement industry is enhancing denitrification efficiency by optimizing its combined SNCR-SCR denitrification processes.
(II) Accelerated Adoption of Intelligent and Digital Technologies
The trend toward the intelligent and digital transformation of industrial chimneys is becoming increasingly pronounced, with intelligent control systems-integrating PLCs and AI modules-gradually gaining widespread popularity. These systems enable real-time monitoring of flue gas emission data and automatically adjust reagent dosing rates and equipment operating parameters; this not only boosts treatment efficiency but also minimizes errors resulting from manual intervention. Concurrently, through the application of big data analytics and cloud computing technologies, enterprises can implement remote monitoring of industrial chimney operational status and generate early warnings for potential faults, thereby enhancing equipment reliability and extending service life.
(III) Integrated Innovation in Green and Energy-Saving Technologies
Driven by "Dual Carbon" goals (carbon peaking and carbon neutrality), the industrial chimney sector is prioritizing integrated innovation in green and energy-saving technologies. Integrated waste heat recovery technologies are gaining widespread adoption; by installing heat exchangers upstream of the denitrification stage, enterprises can utilize the residual heat from flue gas to preheat combustion air or provide heating, thereby reducing overall energy consumption. Furthermore, technologies for the synergistic control of carbon emissions and other pollutants are beginning to emerge; during the desulfurization and denitrification processes, enterprises are simultaneously incorporating steps such as CO₂ capture, thereby laying the groundwork for future integration into the national carbon market.
