Construction of Wet Corrosion Protection Technology for Incineration Plants
Report No.1: Investigation of Wet Corrosion Environment an Actual Incineration Plants
As one measure to improve power generation efficiency in incineration plants, we aimed at low-temperature heat recovery by lowering the temperature of feed water to the economizer. Therefore, in order to investigate the conditions under which low-temperature corrosion (acid dewpoint corrosion and salt deliquescence), which is a problem of low-temperature heat recovery, becomes apparent, a temperature-controlled test piece was exposed to the flue of an actual plant, and the relationship between temperature and corrosion rate was arranged.
