coal fired boiler Agent flue gas temperature dew point

Low Temperature Corrosion in Boiler and Its Prevention

The flue gas dew point temperature increases steeply from with sulphur percentage increasing up to 1% A further increase in sulphur percentage in fuel gradually increases the dew point temperature from 135 degree centigrade to 165 degrees centigrade at 35% sulphur in fuel
