| Abstract: | The IP cylinder rotor and gland-packing system of No.1、No.2 TK-120 steam turbine has been modified according to its operation in TianJia'an power station.The inner efficiency is improved from 85.69% to 91.96%;the heat consumption is reduced from 9294.1kJ/(kW*h) to 9085.18kJ/(kW*h) the vibration of bearing pad in front is from 0.05mm to 0.008mm and 0.1mm to 0.012mm in back;the temperature of thrust pad is from 98℃ to 77℃;the gland-packing system can meet the design requirement.After the modification,the safety and heat efficiency is increased largely.So better efficiency in economics and society can be gained. |
