Control method of adherent air device based on CO/O2 on-line monitoring

The invention provides a control method of an adherent air device based on CO/O2 online monitoring, the device is arranged on a water cooling wall of a boiler, and the control method comprises the following steps of arranging a plurality of detection points; forming a plurality of air supplementing openings, wherein air blown out of each air supplementing opening can cover the multiple detection points; circularly and sequentially collecting sample gas at the detection points; filtering and condensing the sample gas to obtain treated sample gas; analyzing the treated sample gas to obtain the CO concentration at each detection point; setting a first CO threshold A1 and a second CO threshold A2 (A1 < A2); when judging that the CO concentration of any detection point is larger than or equal to A1 and smaller than A2, indicating the detection point is a first to-be-optimized detection point; blowing hot primary air or hot secondary air into an air supplementing opening corresponding to the first to-be-optimized d
