Abstract
The paper describes nitrogen oxide (NOx) abatement by low-NOx burners (LNBs) and combustion modification (CM) for dry-bottom pulverized-coal-fired boilers in Japan. LNBs have been widely used in Japan as a simple way to reduce NOx emissions by 20-50%. NOx abatement by a LNB and CM is much less costly than by flue gas treatment, primarily because of relatively low operating costs. Even when selective catalytic reduction (SCR) of NOx is applied for extensive NOx abatement, it is generally more economical to use a LNB and CM with SCR than to use only SCR. Possible problems with a LNB and CM for coal-fired boilers include increased unburned carbon, slag formation, and tube wastage.
