lbs/MMBtu to ppm (ref. 3% O2, dry) | |||
|---|---|---|---|
| Natural Gas | Propane | #2 Oil | #6 Oil |
| 833 | 711 | 780 | 777 |
| 1368 | 1169 | 1282 | 1277 |
| 599 | 511 | 561 | 559 |
| 2394 | 2045 | 2244 | 2235 |
Example: NOx = 0.15 lbs/mmbtu firing natural gas
NOx in ppm = 0.15 x 833 = 125 ppm

|---|---|---|
| Propane | #2 Oil | #6 Oil |
| 935 | 887 | 880 |
Example: NOx = 0.15 lbs/mmbtu firing natural gas
NOx = 0.15 x 1704 = 226 mg/nm3 (ref 3% O2, dry, 1 atm, 0C)
