The operating principal of the RMB [Rapid Mix Burner] staged firing configuration is to bum as much of the fuel as possible under the high excess air, ultralow NOx conditions. As a result of the fundamental principle mentioned above, this is done by operating the burners air rich (under conditions similar to normal firing, but with higher excess air and with a moderate amount of FGR), where the maximum theoretical NOx, formation is very predictable. Heat is extracted from these air-rich combustion products and cool furnace recirculation products are entrained. The staged fuel is then mixed with the air-rich burner products and combustion is completed. The excess air at the boiler outlet is thus similar to that with normal firing.  3, record 1, English, - air%20rich
