耀一HNCR高分子脱硝技术具有以下的优点：

HNCR脱硝系统的建设为一次性投资，后期运行费用低，高分子脱硝剂价格便宜教不堵塞炉管 。在脱硝过程中不使用催化剂，不存在增加系统的压力损失等其他烟气脱硝技术引起的弊端

HNCR脱硝系统的设备占地面积小;

HNCR工艺的整个还原过程都在锅炉内部进行，不需要另外设立反应器;

HNCR工艺简单，施工时间短;

HNCR技术不需要对锅炉燃烧设备和受热面进行大的改动，不需要改变锅炉的常规运行方式，对锅炉的主要运行参数影响很小。

(1)脱硝化学反应方程式

向温度约850℃～1100℃的烟气中喷入固体脱硝剂，在无催化剂的条件下，脱硝剂与烟气充分混合，选择性的将烟气中的NO还原成N2和H2O，从而去除烟气中的氮氧化物。锅炉烟气中氮氧化物组成中，95%为NO，5%为NO2。

在炉膛内，使用脱硝剂总反应为：4NO + 4NH3 +O2→ 4N2 + 6H2O
