1. SNCR denitration is to inject reducing agent (an water) into the furnace at the temperature range of 800 ~ 1050 ℃, reduce nitrogen oxides into nitrogen and water at high temperature, and realize the discharge of nitrogen oxides up to standard. The denitration efficiency is greater than 50%.

2、SCR 脱硝是将烟气在200～400度 温度下，借助催化剂实现还原反应，将氮氧化物还原成氮气和水， 实现氮氧化物达标排放，脱硝效率大于90%。

2. SCR denitration refers to the reduction reaction of flue gas at the temperature of 200 ~ 400 ℃ with the help of catalyst to reduce nitrogen oxides into nitrogen and water, so as to achieve the standard discharge of nitrogen oxides, and the denitration efficiency is greater than 90%.

3、HNCR脱硝是将还原剂（固体干粉高分子）喷入炉内700～850度区间，在高温下将氮氧化物还原成氮气和水， 实现氮氧化物达标排放，脱硝效率大于80%。

3. Hncr denitration is to inject reductant (solid dry powder polymer) into the furnace at the temperature range of 700 ~ 850 ℃, reduce nitrogen oxide into nitrogen and water at high temperature, so as to realize the standard discharge of nitrogen oxide, and the denitration efficiency is greater than 80%.

4、氧化法脱硝，将fei常稳定的NO氧化成NO2，是利用NO2溶于水的特性，通过喷淋吸收，形成硝酸或亚硝酸，再用碱中和，实现将烟气中的氮氧化物脱除。

4. Oxidation denitration is to oxidize the normally stable no of Fei into NO2. It is to use the characteristics of NO2 dissolving in water, form nitric acid or nitrite through spray absorption, and then neutralize it with alkali to remove the nitrogen oxides in the flue gas.

SNCR+SCR 联合脱硝技术：SNCR/SCR 组合技术是指在烟气工艺中安装 SNCR 和 SCR设备。在 SNCR 部分注入液an等作为还原剂，以部分去除 SNCR装置中的 NOx；在 SCR 段中，通过 SNCR 工艺逸出的an气在SCR 催化剂 H2O 的作用下将烟道气中的 NOx还原为 N2。

Sncr+scr combined denitration technology: sncr/scr combined technology refers to the installation of SNCR and SCR equipment in the flue gas process. Inject liquid an into the SNCR part as reducing agent to partially remove NOx in the SNCR device; In SCR section, an gas escaped from SNCR process reduces NOx in flue gas to N2 under the action of SCR catalyst H2O.

5、低氮燃烧技术改造，通过烟气再循环，jiang低烟气中氧含量，实现折算达标排放。

5. The transformation of low nitrogen combustion technology, through flue gas recirculation, Jiang reduced the oxygen content in flue gas to achieve conversion to standard emission.
