由此控制二次风量大小，以保持最低过剩空气量，达到节能目的。
The flow rate of the secondary air is thus controled, and the excess air is restricted to minimum so as to decrease the fuel consumption of the furnace.
结果表明，在空气过剩系数或空气量不变时，最高燃烧温度和烟气排放温度随燃磷量增加呈单调递增趋势；
The results show that maximum combustion temperature and smog exhaust temperature increase with the increase of phosphorus mass flow rate when excess-air coefficient or air capacity is a constant;
而实际烟气量与氧浓度成反比，与过剩空气系数成正比。
The actual flue gas volume and the concentration of oxygen is inversely proportional, and excess air...
