Which component is used to temporarily alleviate high temperatures at the outlet of the superheater?

• A. Bleeder valve
• B. Thermocouple
• C. Gauge
• D. Thermostatic valve

Answer: (A)

When steam leaves the superheater, cooling or venting excess energy is often needed to keep temperatures within safe limits. A bleeder valve serves this exact purpose: it opens to vent a small amount of hot steam, which lowers the outlet temperature quickly and prevents overheating. This direct venting action makes it the most effective for temporary temperature relief at the outlet. A thermocouple only measures temperature, so it doesn’t change anything. A gauge measures pressure, not temperature relief. A thermostatic valve can regulate flow to maintain a set temperature, but it isn’t typically used to provide the quick, targeted relief that venting via a bleeder valve offers.
