Dear Mr. Ted,

We have the same problem but the color of the stack is yellow. what could be the reason of this yellow color. is this chlorine or SO3/SO2.

waiting for your kind reply

Hello Asif,

Your yellow plume could be caused by excess NOx, in the form of NO2, which is a yellow-orange gas. Do you test for NOx in your stack gases?

Regards,

Ted.
