| Abstract: | On the basis of analysing the operating condition and fault phenomena of MPS type medium speed coal pulverizers equipped for unit no.3 in Huaneng Jinggangshan Power Plant and unit no.5 in Huaneng Fuzhou Power Plant,the loading control function of original coal pulverizers has been retrofitted,the functions,such as logic for tripping the coal pulverizer due to the rollers being unlifted up,and automatic reduction of the set value for reactive oil pressure in case of lowering the rollers for loading the coal ... |
