在锅炉运行中，一般都是通过O2（氧量）来了解送风量是否满足燃烧所需以及进行相应的风量调整，但O2具有不能反映炉内燃烧低劣等缺陷。而CO是燃烧不完全产物，它能反映燃烧工况的好坏。若用O2和CO联合监测、调控锅炉燃烧，则能取长补短、互相补充，并将燃烧控制在不低于临界风
In the boiler operation, O2 (oxygen) is generally to understand whether the supply air volume to meet the needs of combustion and the corresponding air volume adjustment, but O2 can not reflect the poor combustion furnace and other defects. The CO is incomplete combustion products, it can reflect the combustion condition is good or bad. If O2 and CO joint monitoring, control boiler combustion, can learn from each other, complement each other, and will control the combustion at no less than the critical wind
