APPLICATION OF COMBINED NOISE-POWER CONTROL SYSTEM IN MATERIAL LEVEL CONTROL FOR RKD 420/650 COAL PULVERIZER

LI Fazhon

Abstract

The performance features of doubleinlet and doubleoutlet coal pulverizer for 660 MW units in one power plant have been presented,and the signicance of material level control being expounded.The control principle of combined noisepower material level control system has been analysed,and recommendations for adjustment in operation being put forward.The practice of operation shows that the effectiveness of material level control by using said combined control system to be comparatively safe and reliable.
