The dual register burner (DRB) was developed to reduce NO{sub x} emissions from PC-fired boilers, to satisfy federal New Source Performance Standards. Some of the initial applications were also equipped with NO{sub x} ports as a contingency; the ports however, usually proved to be unnecessary and were eliminated. Continuing burner development through the 1980's has resulted in the DRB-type XCL. The XCL is configured to also facilitate use in retrofit applications, in preparation for acid rain NO{sub x} restrictions for existing utility boilers. NO{sub x} emissions for the DRB have proved to be low, but vary with coal properties. NO{sub x} emissions around 0.3 lb/10{sup 6} Btu* are typical for units firing high volatile, free burning coals, but can be twice this value with some bituminous coals.
