| Abstract: | This paper introduces the new heat energy control DCS control strategy during primary air fan frequency converting reconstruction. After actualization, two fashions of primary air fan power frequency and frequency converting are switched under the automation mode with same output and small interference, the control effect is better, to ensure the stable operation of air fan and switch successfully during every operation condition. |
