In order to develop the low NO_x combustion system and high performance steam generator, several tests had been made. The first, to reduce NO_χ emissions , a new type swirl nozzle has been developed. The feature of this nozzle. The second, the combustion tests with package type boiler have been made. From the experimental investigations, NO_χ emission levels emitted from this combustion chamber the grooved swirl nozzle were 30-40 percent less than that of the conventional hollow-cone type swirl nozzle.
