Table 1 to Subpart VVVV—Large Municipal Waste Combustor Carbon Monoxide Limits
| Municipal waste combustor technology | New large municipal waste combustors | |
|---|---|---|
| Carbon monoxide emission limit (parts per million by volume) a | Averaging time (hours) b | |
| Mass burn waterwall | 76 | 4 |
| Mass burn refractory | 76 | 4 |
| Mass burn rotary waterwall | 76 | 24 |
| Modular starved air | 50 | 4 |
| Modular excess air | 50 | 4 |
| Refuse-derived fuel stoker | 100 | 24 |
| Bubbling fluidized bed combustor | 100 | 4 |
| Circulating fluidized bed combustor | 100 | 4 |
| Pulverized coal/refuse-derived fuel mixed fuel-fired combustor | 100 | 4 |
| Spreader stoker coal/refuse-derived fuel mixed fuel-fired combustor | 100 | 24 |
| a Measured at the combustor outlet in conjunction with a measurement of oxygen concentration, corrected to 7 percent oxygen (dry basis). CEMS data during warmup, startup, and shutdown, as defined in this subpart, are not corrected to 7 percent oxygen, and are used as measured. The averaging times are specified in greater detail in § 60.5940(b). | ||
| b Averaging times are 4-hour or 24-hour block arithmetic averages. |
