    摘要: A method of improving the efficiency of large industrial boilers of the type using heat exchangers heated by superheated steam diverted from the steam used to produce energy, which heat exchangers elevate the temperature of the air heater section of such boilers to minimize corrosion caused by the condensation of SO.sub.3 to produce sulfuric acid which comprises reducing the temperature of the air heater by throttling the steam fed the heat exchanger while, at the same time, using an amount of sulfuric acid neutralizing chemical in the air heater section of such boilers to neutralize any increase in the sulfuric acid formed.
