NOx EMMISSIONS IN PPM & mg/nm3

WE HAVE TWO IDENTICAL KILNS SP 4 STAGE PH WITH  UNAX COOLER. NOX MEASURED AT THE FINAL ESP STACK IS

KILN 1 = 293 MG/NM3

KILN 2= 498 MG/NM3

HOW CAN I CALCULATE THEM TO PPM

WHAT SHOULD BE THE NORMAL MG/NM3 OR PPM IN THE VENT STACK ?

WHAT SHOULD BE THE PPM AT KILN INLET ?

ANOTHER KILN SLC GRATE COOLER , NOX MEASURED

KILN PH ESP STACK = 195 MG/NM3

PRECALCINER PH ESP STACK = 1361 MG/NM3

LET ME KNOW THE REASONS FOR SUCH LARGE VARIATION?

WHAT IS THE NORMAL NOX AT CALCINER KILN INLET & PRECALCINOR OUTLET DUCT & WHY?

CAN WE CALCULATE NOX AT EACH STAGE?
