Abstract AR
المرجل هو الجزء الرئيسي في وحدات الطاقة الكهربائية و الذي غالبا ما تعاني أنابيبه من أنواع مختلفة من الفشل.
يعتبر الإفراط بالتسخين و التآكل من أسباب الفشل .يتمثل الفشل بفترات الإفراط بالتسخين الطويلة و القصيرة.
يحدث الفشل أحيانا بسبب تجمعات من الرواسب الناتجة من التآكل أو المواد الغريبة على السطوح الداخلية للأنابيب.
اختيرت في هذا البحث عينات فاشلة من مواقع مختلفة من أنابيب مراجل وحدات الطاقة الكهربائية العاملة في المسيب و تم تحليل الفشل و دراسة أنواع التآكل و محاولة التعرف على أسبابه .
Abstract EN
Boilers are a main part of electric power plants, which mostly suffer from different types of failures.
Overheating & corrosion are considered to be the most important causes of failures in boiler pipes in power plants.
These Failures can be categorized as long- term & short term overheating.
Failures also caused by collection of corrosion products, deposits or other foreign material on the inner surfaces of tubes boiler.
Several failed samples from different locations in the boilers were tested.
The microscopic examination of failure areas of the pipes, showed different types of distortion and clear appearance of corroded area in the microstructures of the pipe metal.
The micro structural analysis of failure and the causes of the failure have been determined and the mechanism of corrosion in one of Iraqi electric power plant has be discussed in this work.
