Abstract:

Abstract:If 6kV busbar outage,pulverizer will trip,and significantly effect on positive pressure direct fired boiler.Especially the 6kV busbar for bottom layer pulverizer,boiler will be highly probably extinguished.To reduce the probability of boiler extinguishing,the probability of boiler extinguishing after pulverizer tripped and the safety of pulverizer power layout were analyzed.The power source improvement plan and the best pulverizer operation mode were indicated.
