Jiahua Jinping Co.,Ltd.---Ammonia-free denitration technology transformation

Customer Reviews：

Jiahua Jinping Cement Co.,Ltd. commented: Through the Huijin denitration technical transformation , the NOx emissions was dramatically reduced, and other indicators also met the contract requirements.

Project Introduction：

Since Jiahua Jinping Cement 2500T/D production line used Ammonia-free Dentration Kiln Tail Sintering System, the ammonia water consumption was decreased from 16.39t/D to 14.38t/D, and the NOx emission was reduced from 330-390mg/Nm³ to 55-96mg/Nm³... All environmental indicators have meet emission legislation. The effect have been highly recognized by customers!
