Question 369Steam Plants - Assistant Engineer

The correct answer is C) corrosive conditions in the boiler. Dissolved gases, such as oxygen and carbon dioxide, can lead to corrosive conditions within the boiler if not properly removed from the boiler feed water. These dissolved gases can cause pitting and other forms of metal degradation, which can ultimately compromise the integrity of the boiler and its components. Removing the dissolved gases through processes like deaeration helps to prevent this corrosive damage and maintain the overall health of the boiler system. The other answer choices are incorrect because they do not directly address the primary reason for removing dissolved gases from boiler feed water, which is to prevent corrosive conditions in the boiler.
