| Abstract: | According to frequent phenomena of internal leakage and jamming in valves of conveying unit of pulverized coal gasification system,some special structure forms of valves are proposed and applied through analyzing causes and mechanism of valves faults.Experimental results show that the faults are effectively reduced by remolding ball valve and adopting new valve structure,which ensures a long period running of conveying unit of pulverized coal gasification system. |
