Methods to prevent corrosion caused by sulfuric acid dew points include: 1) Using low-sulfur fuel to lower the dew point of flue gases； 2) Reduce the dew point by using combustion with a low excess air ratio ； 3) Control the exhaust gas temperature ； 4) Inject additives ； 5) Lower the dew point of water vapor ； 6) Use a corrosion-resistant protective coating ； 7) Use materials resistant to sulfuric acid dew point corrosion. Among these seven methods, using materials resistant to sulfuric acid dew point corrosion is the most effective approach; examples include B485NL, ND (09CrCuSb) steel, 10Cr1Cu, 12MnCuCr, JNS, NS1, etc
