| Abstract: | Taking the steam turbine control for PTA(pure terephthalic acid) unit as an example,the speed-rising process and the unit operating modes switching were discussed,including the leading-in of low and ultra low pressure steam make-up.The steam turbine revolving speed depends on the split-ranging controlled inlet valve,bypass valve and that for leading-in of low pressure steam make-up. |
