| Popis: | In the paper the methodology of condition and behavior diagnostics of boiler constructions is presented, which is necessary to perform in order to make decision on further operation. An algorithm is defined that illustrates the methods for collecting data needed for the diagnostics: analysis of construction, visual inspection, non-destructive and destructive examinations, engineering analysis, experimental measurements and expert condition assessment-diagnostics of behavior. The diagnostics can be significantly improved by the application of finite element method-FEM. The main advantages of this numerical method over the calculation by design norms are expressed through possibilities of determining a nearly realistic image of deformation and stress, and reliable assessment and prediction of boiler construction behavior under service condition. The application of FEM is illustrated by the examples of designing a new firetube boiler and behavior diagnostics of water-tube boiler in service. |
