🔍 Key Concepts

• Soot blowers use steam or air to remove deposits from boiler tubes and gas passes • The effects of trapped condensate in high-pressure steam lines • How water hammer occurs and what components it can damage

💭 Think About

• What happens if a high-pressure steam valve is opened quickly on a line that is partially filled with liquid water instead of dry steam? • Which of the choices describes a problem directly caused by slugs of water moving at high velocity in piping and nozzles? • Which options are more related to fuel/combustion or water chemistry rather than to the mechanical effects inside steam piping?

✅ Before You Answer

• Identify which option specifically mentions mechanical damage from moving water in steam lines • Eliminate answer choices that focus mainly on fuel flame stability or water purity issues • Ask yourself: which consequence is the most immediate and direct result of not draining a steam line before use?
