A STRESS ANALYSIS FOR PRESSURE VESSEL TO PREVENT SPONTANEOUS LGNITION OF COAL STOCKPILE

摘要

A method of analyzing a stress in a pressure vessel for preventing spontaneous ignition of low-carbon according to the present invention includes: analyzing a structure of a simple internal gas tank; Comparing and verifying the output value for the simple internal tank shape with a theoretical value; Performing a structural analysis on the shape of the actual cooling ball; Comparing and verifying the actual value of the internal gas tank shape with the output value; Comparing the theoretical value and the output value of the simple internal gas tank with the theoretical value and the output value of the actual internal gas tank shape to determine stability; Analyzing the structure of the outer shape; Comparing and verifying the output value with the theoretical value of the external shape; Calculating an error rate between a theoretical value and a result value of the outer shape; And determining the stability of the outer shape.
