Q

Scavenging air is supplied to steam sootblower elements to __________.

🔍 Key Concepts

• Role of scavenging air in boiler/sootblower systems • What happens inside a sootblower element during and between blowing cycles • How combustion gases and soot behave in boiler gas paths

💭 Think About

• Think about when scavenging air is flowing: is it mainly during blowing, between blows, or both? How would that timing affect its purpose? • Which choice describes something that requires a continuous, low-volume flow rather than a short, high-pressure blast? • Consider what could happen inside the sootblower if there were no scavenging air – which problem would you most want to avoid for safety and reliability?

✅ Before You Answer

• Match the description of scavenging: is it about cooling, cleaning, or purging unwanted gases? • Ask whether the main risk inside the sootblower is soot on the outside of the element or gases/heat inside the element and head. • Eliminate any option that sounds like the job of the main blowing steam rather than the small scavenging air flow.
