turbine
Thread Content
I would like to ask the experts why interlocks are set for the outlet pressure and temperature of a steam turbine. What are the main consequences if these values are too high? Could you also tell me about the internal structure and working principle of the extraction pump?
Search on the forum; it’s all there.
A low steam temperature can cause water hammer in the turbine, which is manifested primarily by vibration of the turbine structure, damage to the blades, and wear of the steam seals due to such vibration. Low steam pressure forces the throttle opening to be too large; when it is fully open, if the steam pressure continues to drop, the rotational speed will also decrease.
