[Anonymous]

What NOx levels are anybody’s revamped units or new units currently striving to meet? Does anybody out there have experience with ultra-low NOx burners or SCR on coker heaters?

for low NOx I  found in several of our coker heater this spec
 
0.06 lbs NOx/MMBTU heat release
O,04 lbs de CO/MMBtu heat release
O,005 lbs de particulate matter/MMBtu heat release
0,005 lbs VOC/MMBtu heat release
 
also in one of them have
 
NOx 70 ppmv (base in 3% of O2)
CO  20 ppmv
SOx 13 ppmv
Particulate 15 mg/m3
