Method and apparatus for preventing corrosion of compressor impurity separation mechanism

摘要

An alkali control agent (9) is sprayed on the upstream side of a compressor (4a) in the foremost stage of an impurity separation device (6a), and impurities containing at least sulfur oxide in exhaust gas (2) are ejected together with condensation (16) of an after cooler (5a) in the foremost stage of the impurity separation device (6a).
