| Abstract: | Based on the unit startup commission of two typical once-through supercritical boilers(SBC tangentially-fired boiler and HBC LNASB boiler) installed with plasma pulverized-coal igniters,the paper introduced the principle of plasma ignition,summarized its application on newly-built 600 MW once-through supercritical boilers.Under the precondition of ensuring boiler safety,how to launch zero-oil ignition by regulating equipments and operating mode is discussed.In order to improve the economic efficiency of power plant,it is necessary to use plasma pulverized-coal igniters during unit startup and shutdown. |
