To solve the problem of power station boilers' high exhaust temperature and the demand of the dewpoint corrosion prevention and control in the process of flue gas deep cooling, We chose dewpoint corrosion resistant steels BNS, ND and 316L steel as studied objects, which were in situ tested on a boiler of 1000 MW pulverized coal-fired power plant. The results show that 316 L steel is performing superior corrosion resistance. Iron oxides and a small amount of sulphate and chlo-rate are the corrosion products, and the suitable tube metal wall temperature is recommended as 80°C which can avoid the coupling effect between dewpoint corrosion and viscous ash deposition.
