The working principle of the flue gas denitration system is that the urea solution is decomposed into ammonia (NH3) and water (H2O) when encountering high temperature flue gas in the mixing zone of the exhaust pipe. After fully mixing with the flue gas, it enters the catalyst module, where NH3 and NOx react to generate harmless nitrogen (N2) and water (H2O), which are discharged through the exhaust pipe to meet the standard.

尿素溶液分解如下：

The urea solution is decomposed as follows:

尿素经热解、水解生成氨气，为反应提供原料。

Urea is pyrolysed and hydrolyzed to produce ammonia gas, which provides raw materials for the reaction.
