Analysis of large deviation between reheat steam temperature of 200MW unit and main steam temperature of steam turbine side

Abstract With the increasing task of energy conservation and emission reduction, the accuracy of important parameters of the unit is particularly important.In this paper, the main steam temperature on the side of a steam turbine in a thermal power plant is lower than that on the side of a boiler.Through analyzing the possible problems of measuring medium, measuring element, measuring channel and parameter display one by one, the reasons for the deviation of measured parameters are obtained, so as to improve the safe, economic and stable operation of the unit.This article has certain reference value to the similar question.
