Thermocouple Temperature

A sensitive amplifier is described which can be used, in conjunction with a milliammeter, to measure the low voltages encountered in thermocouple temperature measurements. It is much faster in response and more accurate than conventional bourdon tube type thermographs. The virtual absence of either the zero or sensitivity drift, so common in some types of d.c. amplifiers, and the use of battery power make it particularly useful for recording or indicating in remote locations where it must operate unattended.

The performance and efficiency of a steam turbine does depend upon the clearances during the hot conditions. The reliability and accuracy of the clearance calculations is based upon how good are the temperature predictions of the local zones at the secondary steam leakage path. Especially during the transients of the start-up and shutdown of a turbine, the temperature gradients result in the differential expansions of the shell at the top and bottom. This causes the humping or sagging of the shell. Along with the shell, the stationary parts fixed to the shell, such as diaphragms also move up or down. This increases the probability of interference and rubs. These transient gradients are not, in general, captured in the conventional analyses owing to a plethora of reasons. The methods described in this paper are applicable to any section of a steam turbine, as well as a gas turbine. The authors have considered the double flow low pressure (LP) steam turbine inner casing, for which the field data in terms of the metal temperature measurement was compiled and made available. The LP section of a turbine with bottom condenser has, generally double flow arrangement. The thermocouples put on the geometrically symmetrical points indicated difference in temperature and thus the circumferential variation. The paper describes how a few temperature measurements on the shell using thermocouples can be effectively utilized to calculate the temperature as a boundary condition at all the nodes of the finite element (FE) model by means of shape function interpolation. The results based on this technique give a continuous temperature distribution. The thermocouple based shell temperature measurements in the field are used for the calculations of the temperature at each point and the structural analysis was carried out. The analysis did indicate the sagging & humping of the shell. Plans for future improvements will be presented. Temperature and deflection profiles and transient errors are shown to be representative of observed behavior.
