Influence of increased primary air ratio on boiler

2018-6-1 · The boiler performance deteriorates severely when the momentum of PA and SA are too close, which should be avoided in real boiler operation. When high moisture brown coal is used, a feasible solution is suggested to increase the temperature of PA, rather than the ratio of it, to meet the increasing requirement of drying capacity in the mill system.
