Has any new analyzers become available for testing ammonia slip? And do you do any testing for SO3 and what affects ammonia has on your results if any?
When it is put on the coal belt it is supposed to have a positive affect on Hg removal. Have seen some testing done with soda ash also. It was feed in with the coal also. Was just wanting a little more info on the trona.
The trona injection I have seen is in dry powder form and is injected after the air heater outlet. Also have heard of it being feed in with the coal as a dry form also.
Just curious if anyone has dealt with this, and what results you got with reductions of SO3 on a COAL fired power plant. And the affects on the equipment at the plant , if any.
Thanks

Thnx for the reply. The blue plume seems to be common for the 3 scr's i have been around, with all three having different so2 and 3 levels. The scr's are new to the area and they are still tuning them up i guess.
Alex,
yes they are injecting ammonia for contro; of Nox i believe. Why does ammomnia cause a blue plume? ANd this unit has the SCR's on it also, but there hasnt been any high levels at SO3 at this plant, as thought. There has been no testing to see what ammonia is coming out of the stack and...
