🔍 Key Concepts

• Boiler combustion and excess air – how air supply affects furnace temperature and heat transfer to the superheater • Feedwater temperature – how hotter or colder feedwater changes boiler firing rate at constant load • Priming/carryover – how water droplets in the steam affect superheater performance and steam temperature

💭 Think About

• At constant load, what condition inside the furnace or boiler would cause the gas temperature entering the superheater to increase? • How would too little or too much excess air change furnace gas temperature and therefore superheated steam temperature? • If the steam leaving the drum contains water droplets (priming), what effect does that have on the temperature of the steam going through the superheater?

✅ Before You Answer

• Identify which option would raise furnace gas temperature at a given steam load, thus raising superheat outlet temperature • Eliminate any options that would tend to cool the steam or reduce gas temperature entering the superheater • Consider whether priming and very wet steam would more likely lower or raise final superheat temperature
