🔍 Key Concepts

• Purpose of soot blowing in a boiler (what problem are you preventing or correcting?) • How moisture or condensate in air lines can affect pneumatic equipment • What boiler conditions should be stable and within normal operating range before soot blowing

💭 Think About

• Which action directly protects the pneumatic soot blower equipment itself from damage or poor operation? • Which options could actually make boiler operation less safe or less efficient during a soot-blowing sequence? • Think about what you want the condition of the boiler and its air systems to be like: hot, stable, and clean, or temporarily weakened/unprepared?

✅ Before You Answer

• Verify which choice deals with preparing the soot blower system, not changing normal boiler operating parameters • Eliminate any option that would intentionally reduce safety margins (for example, water level) • Consider whether condensate in air lines is good or bad for moving pneumatic parts and valves
