| Refuse-derived fuel stoker | 200 | 24 |
| Fluidized bed, mixed fuel (wood/refuse-derived fuel) | 200 | c 24 |
| Bubbling fluidized bed combustor | 100 | 4 |
| Circulating fluidized bed combustor | 100 | 4 |
| Pulverized coal/refuse-derived fuel mixed fuel-fired combustor | 150 | 4 |

a Measured at the combustor outlet in conjunction with a measurement of oxygen concentration, corrected to 7 percent oxygen, dry basis. Calculated as an arithmetic average.
b Averaging times are 4-hour or 24-hour block averages.
c 24-hour block average, geometric mean.
