Taiyangshi cement Group---Ammonia-free denitration technology transformation

Customer Reviews：

Taiyandshi Cement Group commented:" Huijin Ammonia-free Dentration Kiln Tail Sintering SystemTechnology Transformation have perfect effect, the standard coal consumption of per ton of clinker was reduced by 2kg. we are satisifed with that .

Project Introduction：

Since Ammonia-free Denitration Kiln Tail Sintering System technical transformation was used in Henan Taiyangshi Cement Group, reducing the ammonia water consumption from 14,4 t/day to 11.52 t/day, saving expense of ammonia water for 470,000 CNY per year, and reducing the NOx emissions from ≤250mg/Nmm³ to ≤150mg/Nm3.
