Abstract Measurement model of air flow rate in burner vents are presented, according to conventional configuration of measuring instruments in thermal power plant. Resistance characteristics of air regulation dampers are automatically extracted from running data by mechanism modeling and data mining technology, and costs of laboratory calibration tests are saved. The discharge flow characteristics of air regulation dampers are measured in a practical boiler by experiments, and compared with curves extracted from the running data, they match very well. Air flow rate measurements in burner vents makes it possible to monitor air and fuel distribution in furnace, it facilitates burner control and optimization in low NOx pulverized-coal-fired boiler.
