Numerically modelling temperature deformations and stresses in the exhaust system of a gas compressor unit

During the operation of a gas compressor unit, the temperature of the exhaust system can cause failure or burnout of the inner facing sheets of the unit. The article describes a technique for determining the maximum temperature deformations of these elements. The technique enables more accurate calculation of the temperature deformations by determining the influence of the contacts between the inner facing and the power frame on the temperature distribution and mobility of the exhaust system. The temperature deformations and stresses of the exhaust system elements are determined, and the level of the permissible stresses is evaluated. The results of the work can be used to prevent possible ruptures and burning of the inner facing, as well as to calculate the design dimensions of the lens expansion joint.
