| Abstract: | s: Focusing on the problem there existed error when air flow rate and speed of secondary air was measured for brown coal boiler of 200 MW unit, taking use of a new type air turbine flow-meter and AS220-EA control system, the result of measurement in each measuring point was processed by linearization after they were calibrated on site, with which its precision of measurement was promoted and the reliability of secondary air measure system on-line was also improved, operators can easily adjust boiler operating situation with the system. |

| Keywords: | boiler secondary air measure on-line turbine flow-meter wind speed air flow rate |
