Steady State Heat Conduction Structural Thermal Analysis of Boiler Tubes and its Design Attributed Failure

Abstract

One of the important parts of the thermal power plants are tubes carrying steam generally called as boiler tubes. Any leakages in these tubes cannot be identified easily with human senses and also boiler operating condition it is impossible to investigate these tubes or leak. In order to do inspection it require shut down of the plant involving production losses. Though we do inspection with human abilities there is possibility of occurrence of error. Frequent shut downs for inspection leads to huge production loss. In recent days boiler explosions and its impact have become regular news. The intent of this paper is to identify design related failure of the boiler tubes under the thermal loading conditions. A single boiler tube is designed and its behaviour under thermal load operating conditions has been studied with the help of Ansys R15 student release simulation software. This paper gives the detailed study of the more vulnerable regions of boiler tube in design aspect.
