1) It is used in many demineralized water boiler scale.

2) Boiler scale cleaning and prevention with low grade radioactive rays is a new green conservation energy technology.

3) The results showed that serious boiler scale caused long term overheat and creep of boiler plates which resulted in the drum shape deformation of cylindrical body of boiler.

4) This paper emphasized the analysis of the formative reason for boiler scale and its harm, and presented the precaution measures and solutions.

5) Stellite 6 seats and fully-guided Stellite 6 discs resist the excessive corrosion and erosion effects aggravated by grid and boiler scale particles and high temperature changes.

6) This paper makes a discussion on the formal cause and hazard of boiler scale, and puts forward blowing out as planned in order to keep boiler water measure up to standard.
