| Abstract: | This paper analyzed the reason of the test error about the inlet primary air quality of the medium speed pulverizer, and calibrated the flow coefficient of the aerofoil wind quality gauging apparatus, then modified the DCS configration and ensured the nicety of the powder-air ratio automatic control curve of the milling system. Thesemeasures make sure the boiler operate safely and economically. |
