The oxygen content in the flue gas was recorded over a period of 24 h. The scan cycle of the Distributed Control System was 200 ms, the sampling frequency was 5 Hz, the resolution of the data acquisition system was 0.1%, and the uncertainty of the sensors was all 1.0%. Fig. 8 shows a typical set of results over a period of an hour. Fig. 8 shows, over this typical hour in time, the data on the left of the furnace are lower than that on the right of the furnace. The reason for this phenomenon is believed to be because the vertical section of the boiler flue is so large that the distribution of oxygen content is uneven. This slow fluctuation of the measurement from each analyzer was observed during the plant demonstration trials. When the measurement data are obtained, their consistency should be checked to eliminate the influence of spurious data on the oxygen measurement. B. Data Consistency Check To ensure the accuracy of the measurement data from the multisensors, the first step is to complete the selection of initial data and minimize the gross errors. Gross errors are undetected errors that will cause a measurement to deviate significantly from the mean value [27]. The data consistency check is undertaken as follows. |
