Detection method and detection device for carbon dioxide emission based on oxygen content determination

The invention discloses a detection method for carbon dioxide emission based on oxygen content determination. The detection method is used for calculating the carbon dioxide emission through a difference value between the content of oxygen in air entering combustion equipment and the content of oxygen in flue gas discharged out of the entering combustion equipment. The detection method is simple in process, smaller in data fluctuation, accurate in analysis and low in detection cost. The invention further discloses a detection device applied to the detection method, which comprises an air flow determining device, a flue gas flow determining device, a flue gas oxygen content determining device and a data analysis device. The detection device can realize on-line detection and is high in detection speed. 本发明公开了种基于氧含量测定的二氧化碳排放检测方法，其通过进入燃烧设备的空气中氧含量与排出燃烧设备的烟气中氧含量的差值计算二氧化碳排放量，该方法过程简单，数据波动较小，分析精准，检测成本低。本发明还公开了种应用于上述检测方法的检测装置，包括：空气流量测定装置、烟气流量测定装置、烟气含氧量测定装置及数据分析装置。该装置可以实现在线检测，检测速度快。
