| description | The invention provides a method and device for determining the air leakage amount of an oxygen-enriched combustion boiler, and relates to the technical field of boiler air leakage amount determination. The method comprises the following steps: according to as received basis coal parameters, oxygen injection parameters, flue gas recirculation extraction point parameters and atmospheric parameters, obtaining the smoke discharge amount, the condensed water vapor amount, the boiler total air leakage amount, the oxygen injection amount and the recirculation flue gas amount of unit mass of as received basis coal; and obtaining the air leakage rate of the target equipment according to the variables, the extraction point parameters of the target equipment and the extraction point parameters of the next adjacent equipment of the target equipment. According to the method and the device, the air leakage amount of the target equipment in the oxygen-enriched combustion boiler can be determined feasibly, and the number of |
