This report compares the installed capital and operating and maintenance (O&M) costs of reverse-air baghouses, pulse-jet baghouses, and electrostatic precipitators (ESPS) for utility coal-fired applications. For a 250-MW boiler, the pulse-jet baghouse capital cost ($50/kW installed) is 20% lower than an ESP with a 400 SCA ($63/kW installed) and 30% lower than a reverse-air baghouse ($71/kW installed). The levelized cost for the pulse-jet baghouse and the ESP is similar (3.4 mill/kWh) and lower than the reverse-air baghouse (3. 8 M/kWh). In general, ESPs are the economic choice for coals with high-sulfur content or low-resistivity fly ash, whereas baghouses are the choice for coals with low-sulfur content and high fly ash resistivity. When controls for increasingly stringent emission limits were evaluated, baghouses became increasingly attractive for all coals. However, even at emission limits less than the current New Source Performance Standards (less than 0.03 lb/MBtu), the ESP still has an economic advantage for very precipitable, low-resistivity fly ash from high-sulfur coals.
