In order to fully mix the reductant with NO

x

in the selective catalytic reduction flue gas denitration technology

it is the best situation that the mass concentration distribution of reductant is consistent with the mass concentration distribution of NO

x

. Something was mainly introduced about measuring point layout

measuring method

test results and analysis

etc. in the test of adjustment to ammonia injecting adaptability in SCR flue gas denitration system. It can effectively improve the adaptability of ammonia injecting in SCR

reduce the amount of ammonia escape

reduce the export concentration of NO

x

that the manual valves are adjusted in each spray ammonia branch pipe.
