【 摘 要 】

The objective of this project is to develop an environmentally acceptable and cost-effective NO{sub x} control system that can achieve less than 0.15 lb NO{sub x}/10{sup 6} Btu for a wide range of coal-burning commercial boilers. The system will be comprised of an ultra low-NO{sub x} PC burner technology plus a urea-based, selective non-catalytic reduction (SNCR) system. In addition to the above stated NO{sub x} limit of 0.15 lb NO{sub x}/10{sup 6} Btu, ammonia (NH{sub 3}) slip levels will be targeted below 5 ppmV for commercial units. Testing will be performed in the 100 million Btu/hr Clean Environment Development Facility (CEDF) in Alliance, Ohio. Finally, by amendment action, a limited mercury measurement campaign was conducted to determine if the partitioning and speciation of mercury in the flue gas from a Powder River Basin coal is affected by the addition of Chlorides to the combustion zone.
