🔍 Key Concepts

• Superheater function – what it does to steam after it leaves the drum • Effect of furnace heat/air flow on gas temperature at the superheater • Relationship between desuperheating and steam temperature control

💭 Think About

• Ask yourself: Which option would tend to make the gas temperature around the superheater tubes hotter, not cooler? • Which options would actually work against a high outlet temperature by either adding water or removing heat? • How does too little air versus too much air affect combustion temperature and thus the temperature of gases hitting the superheater?

✅ Before You Answer

• Identify which choices would add water to the steam and therefore tend to reduce temperature. • Identify which choices would increase furnace gas temperature reaching the superheater. • Consider which device – superheater vs. desuperheater – is intended to raise vs. lower steam temperature.
