: Hi! My name is Letitia Langens and I am a third year mechanical engineering co-op student. I am currently work on methods for cleaning scale build-up from the inside of a steam turbine combined reheat valve (CRV). I have been told that the scale forms due to contaminants in the steam and that oxygen dosing can help to remove the contaminants. Are there any other methods known that will effectively remove contaminants and prevent scale build-up?
Where is the scale precipitating out, on the turbine blading or on the reheat valve surfaces?
