The invention discloses a boiler operation method. A boiler comprises a combustion area (1) and a flue. The boiler operation method comprises the steps that oxygen-rich gas enters the combustion area to be combusted, all sections in the boiler are in the micro-positive pressure state, and a plurality of pressure measurement points are arranged along the way inside the combustion area and the flue to detect the smoke pressure of each section in the boiler; when smoke pressure measured by one or more pressure measurement points is larger than or lower than a preset micro-positive pressure range, a pressure balancing device is used for stabilizing the smoke pressure at the corresponding pressure measurement point to be within the preset micro-positive pressure range. The boiler operation method not only is applicable to an oxygen-rich combustion boiler, but also is applicable to a traditional air combustion boiler, can comprehensively and accurately monitor the pressure inside the boiler, stabilizes the pressure inside the boiler to be within the micro-positive pressure range and enables the boiler to operate under the preset micro-positive pressure, thereby reducing air leakage, ensuring safe operation of the boiler and effectively improving the concentration of CO2 in smoke as well.
