Ammonia Escape Application of power plant

Customer Name ：China Datang Coporation
Running Time ：2017-04
Site Condition: there are 8 stations in the field, 1-6# unit is 330MW, and 7-8# unit is 600MW. The exhaust gas situation  as follows:

Field process: after the furnace flue gas comes out, it is denitrification through the first grade SNCR (the ratio of urea adding water), and then denitration by the SCR denitration device.
Measured Gas： NH3 ：0-20ppm

The sampling point is on the slope of the rectangular flue before the 2# unit SCR denitration pipe exits.
Flue gas temperature : 400 ℃ ,
Pipe diameter ：2 meters.
Gas flow velocity: 0-30m/s
Gas pressure： -5Kpa ~ +5Kpa
Flue gas temperature： 400℃.
