Boiler cold start using pulverized coal in ignitor burners

Abstract. An ignition, warm-up and low-load-stabiliztion system for furnaces fired by pulverized coal is described. In conjunction with a system in which pulverized coal is sent directly from a coal mill to a load-bearing nozzle and in which combustion air is brought to the nozzles from an air preheater that uses hot furnace gases to warm the combustion air, ignitor nozzles are provided that
