| Abstract: | Author has briefly described the process flow of Shell coal gasification plant and the process principle of pulverized coal conveying system; has analyzed the existing problems and its reason for hard sealed and floated ball valve adopted in the pulverized coal conveying unit;has proposed the technical reformation measures for hard sealed / floated ball valve replaced by the two-way disc valve. Result indicates that since starting to try to use the disc valve on April in 2011 in B series of pulverized coal conveying unit, no fault and also no inner leakage occur up to now. |
