Abstract
This paper makes an analysis on the causes of coupling effect in a two-sectional drum water level control system. A modified control strategy of the drum level control was put into a test run during the commissioning of an imported unit. Based on the testing result
an ideal operational mode of the two-sectional drum water level control system
which makes full use of the speed governing feature of Weir pump
