| Abstract: | High temperature corrosion takes place predominantly on the fired-side of the tubes,including water cooling tubes,over-heater tubes,re-heater tubes and coal saver tubes (namely the "four tubes"),in the boilers in coal fired power plants.The major corrosion forms are sulfidation,chloridation,oxidation in water vapour and hot corrosion induced by vanadate.The high temperature corrosion processes and mechanisms have been reviewed and the measures for prevention briefly summarized. |
