Abstract: | Factors causing damage to the metal of the drums of high-pressure boilers, as well as the known cases of drum failures, are analyzed. The totality of factors determining the operational reliability of drums is systematized. The process-related mechanism governing the destruction of the drums at the Kurgan cogeneration station and TETs-3 Yaroslavl cogeneration station, and the general factors caused these drums to fail are identified. Recommendations for reducing the risk of drum failures are formulated. |
