As research in the field of atmospheric pollution deepens, the concept of "cities in the atmospheric pollution transmission corridor in the Beijing-Tianjin-Hebei region" has gained consensus. In February 2017, the Ministry of Environmental Protection issued the "2017 Air Pollution Control Program for the Beijing-Tianjin-Hebei and Surrounding Areas," referring to the corridor cities as the "2+26" cities. This includes the two provincial-level municipalities of Beijing and Tianjin, as well as the 26 prefectural-level cities under the jurisdiction of four provinces within a radius of about 700 kilometers around them.
Xinxiang Great Wall Machinery始终坚持绿色发展原则, powered by science and technology, continuously upgrades its industrial waste resource utilization plans. Regarding the "Comprehensive Management of Industrial Air Pollution" indicator among the seven indicators of the "Plan," Xinxiang Great Wall Machinery has developed a technological solution, the "Flue Gas Recirculation Energy Saving Process Equipment," committed to helping more slag vertical mill production line manufacturers reduce energy consumption and waste gas emissions, thereby lowering production costs and enhancing environmental benefits.
Four Advantages of Xinxiang Great Wall Machinery's Hot Air Furnace Technical Transformation
1. NOx emissions
Burner and furnace co-designed for low nitrogen emissions, utilizing large flue gas recirculation; exhaust NOx content ≤ 50 mg/Nm³ for slag vertical mill production line.
2. Low gas consumption
Emission recirculation efficiency increased from 40% to 50% to 80% to 90%; enhanced heat utilization, reduced gas consumption per ton of ore powder.
3. Low environmental tax burden
Significant reduction in exhaust emissions, lowering environmental tax obligations.
4. No-cement structural design
No refractory material is designed inside the furnace body; issues such as refractory brick detachment due to frequent start and stop of the production line.
To fully implement the green development concept, Xinxiang Great Wall Machinery has improved its proprietary 600,000 tons/year mineral powder production line's gas hot air stove, ultimately reducing production costs and enhancing environmental benefits. As shown in this diagram, the nitrogen oxide emissions of the flue gas recycling energy-saving hot air stove are less than 50g/Nm³ for finished mineral powder, with a natural gas consumption of 8.2 Nm³. The annual savings in natural gas alone amount to 5.44 million yuan.
Industrial coal-to-gas conversion is the new trend. If you're looking to upgrade your hot air furnace technology, achieve Nox emissions reduction and low gas consumption, among other technical issues, don't hesitate to get in touch with us!
