Most common method of speed control which is employed in paper and pulp industries is by using level controller. In this method, level is maintained constant at each stage. But this method of level control leads to power loss at each stage. Another method is speed control of medium consistency pump using consistency control. By employing consistency control and maintaining consistency at a constant value, power loss can be reduced. Initially the method of speed control that is employed in Seshasayee Paper & Boards Ltd, is by the use of level control. Power loss was more while employing level control method. It has been synchronized level control with consistency control. By this method power loss was reduced to some extent. Variable Frequency Drive (VFD)'s are used where there is fluctuation in load. Distributed Control System (DCS) is used to control the level of water in the pulp. By taking several samples and analyzing, we found that by maintaining consistency at a value of 3.5, power loss was considerably reduced. If the value consistency level increases or decreases, the power loss also increases.
