Temperature of turbine extraction steam system 
——————————————————————————————————————————————————————
The measurement points of the steam extraction system of the turbine include steam temperature of high-pressure heater inlet, steam temperature of deaerator in;et and steam temperature of small turbine. Generally, medium-temperature and medium-pressure thermowells are used, and 1Cr18Ni9Ti is selected as the material of thermowells.
