| Abstract: | To solve problems like fracture and drop of the thermal-protective materials in the thermal-protective tiles lining when the suoercharged boiler runs and stops repeatedly.This paper uses the finite element method to check the strength of the thermal-protective tiles lining,finding out the components that may appear destruction and their reasons of the fracture.We can offer the guide how to run a suoercharged boiler safely and predict destructions. |
