A malfunction in the DC heater is indicated by __________.

🔍 Key Concepts

• Function of a DC (de-aerating) heater in removing dissolved gases from feedwater • Normal flow path of steam, condensate, and vented gases in a DC heater • What an abnormal vent flow or chemical usage might indicate about heater performance

💭 Think About

• Think about what the primary purpose of a DC heater is and what symptom would most directly show that it is NOT removing dissolved gases effectively. • Consider which choice describes something that would be expected in normal operation versus something that would signal a problem or inefficiency. • Ask yourself: which option points to non‑condensable gases not being properly removed, and which options simply describe normal heat‑transfer or mixing?.

✅ Before You Answer

• Identify which options clearly describe normal design operation of a DC heater (how steam and condensate are supposed to interact). • Decide which symptom would force you to adjust water treatment (chemicals) because the DC heater isn’t doing its job well enough. • Check which option involves non‑condensable gases venting in a way that suggests something is not working correctly.
