🔍 Key Concepts

• Purpose of sootblowing (what condition are you trying to achieve in the gas path and on tube surfaces?) • What each device/indicator in the choices actually tells you about boiler or engine conditions (steam manifold drains, scavenging air indicator, smoke indicator/periscope) • Manufacturer’s normal practice for sootblower operation (fixed vs. condition‑based number of revolutions)

💭 Think About

• Which indicator, if any, directly shows you whether combustion gas passages and tube surfaces are still shedding soot or have become relatively clean? • Do steam supply drains or scavenging air indicators tell you anything about the cleanliness of boiler tubes, or do they serve a different purpose? • If you limited sootblower rotation to a fixed number of turns every time, could that reliably account for different soot conditions and firing rates?

✅ Before You Answer

• Match each choice with what it actually monitors (steam quality, air box condition, or gas path cleanliness). • Ask: which one changes visibly during sootblowing and lets you see when soot carryover has decreased to a normal level? • Eliminate any answer that refers to systems not directly part of the boiler gas path/tube cleaning process.
