Evaluation of the principal stresses in a deaerator vessel of a thermoelectric power plant

摘要

This paper addresses the problem of stress evaluation in a typical deaerator operating in a thermoelectric power plant. The stress analysis problem was initially numerically evaluated, and then monitored by means of a strain gauge set-up. The main results presented clearly indicate the need for constant monitoring, since this experience has shown that deaerator vessels can sometimes operate outside the original design condition.
