coefficient of excess air

Under the condition of constant phosphorus mass flow rate, the smog exit temperature would increase slowly while other parameters would decrease with increasing excess air coefficient.

在燃磷量不变情况下，最高燃烧温度、壁面最大热流和平均热流均随过剩空气系数的增大而减小，但烟气出口温度缓慢增加。

Because of the great disturbance of boiler burning system, on the spot, we don't find absolute excess air coefficient but its optimum interval.

由于锅炉燃烧系统的扰动较大，我们实际寻取的是相对的最佳过量空气系数，更为重要的是找到最佳过量空气系数区间。

Through experiments of excess air coefficient on the PC combustion in stove, it is concluded that it is no use to add too much air at the beginning of free-oil ignition of PC.

本文通过研究过量空气系数对炉内火焰的影响规律，指出在煤粉无油点火初期不宜补充大量二次风。
