Babcock Wilcox engineering studies followed by pilot-scale testing has developed/confirmed the potential of utilizing gas, oil or coal reburning as a viable NO{sub x} reduction technology. To date, two US sponsored programs promote natural gas/oil as a reburning fuel because it was believed that gas/oil will provide significantly higher combustion efficiency than using coal at the reburn zone. Although B W has shown that gas/oil reburning will play a role in reducing NO{sub x} emissions from cyclone boilers, B W coal reburning research has also shown that coal as a reburning fuel performs nearly as well as gas/oil without deleterious effects on combustion efficiency. This means that boilers using reburning for NO, control can maintain 100% coal usage instead of switching to 20% gas/oil for reburning. As a result of the B W performed coal reburning research, the technology has advanced to the point which it is now ready for demonstration on a commercial scale.
