锅炉炉胆稳定性的解析法分析

Stability analysis of boiler biliary with analytical method

研究了圆柱壳和圆锥壳的临界载荷,进行了锅炉炉胆的稳定计算,把简单公式的计算结果和有限元计算结果进行比较,计算结果表明,二者非常吻合;应用简单公式计算了某失稳锅炉炉胆的临界载荷,分析了事故原因;另外,计算了正常工作的某型号锅炉炉胆的临界载荷,为锅炉炉胆的设计和计算提供了依据。

The critical load of the cylindrical shell and the conical shell are studied, and the stability of the boiler biliary is calculated. The simple formula calculation results and the finite elment calculation results are compared, which showed that both of the results are in good agreement. By using the simple formula to calculate the critical load of an instability boiler biliary, the cause of the accident is analyzed and the critical load of a particular model boiler biliary is calculated, which provides the basis for the design and calculation of boiler biliary.
