1 High denitration efficiency, the most suitable temperature for catalytic reaction, and the denitration efficiency is 95 ~ 98%;

2 Low energy consumption, first dedusting and then denitration, without cooling and dedusting + heating and denitration to reduce heat loss;

3 Small floor area, integrated design and high integration, which can be transformed in situ;

4 Small catalyst volume, small pore size (large specific surface area) catalyst after flue gas purification, saving consumption;

5 Save system investment, optimize the design of ammonia vaporization and mixing of ammonia and NOx, and reduce corresponding auxiliary facilities;

6 Stable operation, simple system, mature technology and wide application.
