Oxygen Content Measurement System Eight zirconium oxygen analyzers were used to measure the oxygen content in the flue gas of a 300-MW coal-fired boiler. The analyzers were mounted between the superheater and the economizer of the boiler where the flue gas temperature was appropriate. The flue gas system of the boiler is schematically shown in Fig. 6 [26]. The flue gas flows from the lower level of the furnace to the upper level along the solid lines (Fig. 6). All analyzers were all calibrated prior to despatch to the power station and further calibration should not be necessary [12]. However, due to specific installation conditions (presence of dust, gas corrosion, etc.) at the coal-fired power station, the sensors were recalibrated six monthly or sooner through a standard two-point (zero, full scale) calibration process. When the calibration hole was connected to the air, the oxygencontent should suggest the oxygen content of the air. If not, an on-site recalibration was undertaken by connecting a standard gas with an oxygen content of 6% to the calibration hole. It can be observed from Fig. 6 that there were four air preheaters (air preheaters 1–4), four main motors, and four standby motors. The outputs of four main motors are 13.5,13.8, 13.8, and 14.0 A, respectively. The four standby motors were not used during the tests. NR321, NR322, NR421, and NR422 are the flue gas baffles in the entrance of air preheaters. NR319, NR320, NR419, and NR420 are the flue gas baffles in the outlet of air preheaters. S1, S2, . . . , S8 represent the zirconium oxygen analyzers, one on each side of each air preheater (as shown in Fig. 7). A total of eight zirconium oxygen analyzers were installed, four (S1, S2, S3, and S4) on the left side of the furnace while the other four (S5, S6, S7, and S8) on the right of the furnace. |
