[0040] Specific Example 1
[0041] The following combined with the drawing of the distributed energy denitration system of a certain power plant gas internal combustion engine as an example, and the present invention will be further described.
[0042] In this first embodiment, the development project is studied in the use of SCR method flue gas denitration process, and the reducing agent is urea, and ammonia gas is prepared by the urea solution thermolysulofer, so that the system can achieve a nitrogen oxide (NOx) emission indicator below 30 mg / The purpose of NM3. High efficiency evaporation pyrolysis device and denitration system such as Figure 4 As shown: The gas internal combustion engine generates a flue gas temperature of 370 to 550 ° C, up to 600 ° C, and the power generation force is 4.4mW, and the amount of flue gas is from 100% in the gas internal combustion engine load. 19500 nm3 / h. At the state, the NOx is 350 mg / nm3 under the dry base 5% o2, and the flue gas ente...
