Due to the resource-intensive nature of hot air furnace usage, coupled with the significant pollution generated by traditional hot air furnaces, upgrading and transforming the hot air furnace technology is currently the main task.
Traditional hot blast furnace process drawbacks
1. Incomplete coal slag combustion leads to severe energy waste.
2. High gas consumption, with a 40% to 60% utilization rate of flue gas, leading to high enterprise costs.
3. High NOx emissions, high oxygen content in exhaust gases, and high emissions standards after conversion.
Xinxiang Great Wall We steadfastly adhere to the principle of green development, driven by science and technology, continuously upgrading our waste residue resource utilization plans, focusing on the seven indicators of the "Plan"."Enhancing Comprehensive Governance of Industrial Air Pollution," Xinxiang Great Wall Machinery innovates with the introduction of the "New Type Flue Gas Recycling Energy-saving Process Equipment." This is aimed at assisting more slag vertical mill production line manufacturers in reducing energy consumption and waste gas emissions, thereby lowering production costs and enhancing environmental benefits.
Xinxiang Great Wall Machinery's Hot Air Furnace Technical Transformation - Four Major Advantages
Ultra-low NOx emissions
Burner and furnace collaborative low nitrogen design, utilizing large flue gas recirculation, slag vertical mill production line exhaust gasesNOx content ≤ 50 mg/Nm³
2. Low gas consumption
Tail gas recirculation efficiency isIncrease from 40% to 50% to 80% to 90%; enhance heat utilization efficiency, reduce gas consumption per ton of mineral powder.
3. Low environmental tax burden
Significant reduction in exhaust emissions, leading to lower environmental tax payments.
4. Non-cementitious structural design
The furnace design does not include refractory materials, eliminating issues such as refractory brick detachment caused by frequent start-ups and shutdowns of the production line.;
Xinxiang Great Wall Machinery can carry out technical upgrades for gas hot blast furnaces in industrial waste residue production lines. Welcome to inquire and request quotes!
