Question 276Steam Plants - 1st Asst/Chief
70% to passWhen a boiler water test indicates a pH value of 6, you should _______________.
Achemically treat to raise the pH to normal level
Bcheck the DC heater for possible malfunction
Cbegin a continuous boiler blow down
Dchemically treat to lower the pH to normal level
AI Explanation
The correct answer is A) chemically treat to raise the pH to normal level. When a boiler water test indicates a pH value of 6, it means the water is acidic, which can lead to corrosion and other issues. To address this, the proper action is to chemically treat the boiler water to raise the pH to the normal operating range, typically between 8.0 and 10.5. This helps maintain the boiler's integrity and efficient operation. The other options are not the correct response in this situation. Checking the DC heater (B) is not directly related to addressing the low pH, and beginning a continuous boiler blowdown (C) would not resolve the underlying pH issue. Lowering the pH further (D) would exacerbate the problem.
