Avoiding Boiler Chimney Corrosion - Forbes Marshall

Corrosion rate also increases during such conditions. In order to minimize the chimney corrosion, following steps should be taken: 1. Keep flue gas temperature at boiler exit well above the dew point limit for fuel used- preferably 50 Deg. C. more than the dew point limit. 2. Eliminate any points from where air can seep into the flue gas path. 3.
