Hello Mohan,

Have you tested the stack gases to determine if the orange plume is NOx or fine particulates?

Regards,

Ted.

Sir,

  Kiln stack NOX is 742.66mg /m3. Can you explain in what way it leads to orange plume?

Hello Mohan,

NOx measures both NO (which is colourless) and NO2 (which is a deep orange), however once the NO comes in contact with air it converts into NO2. 

Under certain conditions, a yellow-orange plume can be seen even at NO2 concentrations as low as 500ppm.

Regards,

Ted.
