This paper measured the Mossbauer spectra of high and medium pressure boiler corrosion products and identified the phase composition. (A) Experimental Section 1. Rust samples of medium pressure boiler corrosion products A, B, C were taken from the inner wall of 2 ~ # boiler water wall tubes in Guangzhou Power Plant. The pressure in the tubes was 40 kg / cm ~ 2 and the temperature was 250 ℃. Rust samples D and E were taken from the inner wall of the superheater tube (425 ℃) and economizer tube (150 ℃) respectively. 2. Corrosion products of high pressure boiler Rust samples F, G and H were taken from No. 3 boiler of Shaoguan Power Plant in Guangdong Water wall tube wall, tube pressure 110kg / cm ~ 2, temperature 320 ℃.
