| Abstract: | Through inspection serious problems from the 3rd boiler of a sugar refinery were found and the water-wall tubes were deformed and invalid.Macro and micro-testing methods were used to analyze the accident.Results show that the overloading of the boiler causes bad water cycling.In addition,improper operation,inaccurate control instruments and lack of management are among unignorable reasons.For such accidents,some corresponding preventive measures were put for ward. |
