🔍 Key Concepts

• Function of a dry pipe in a boiler • Location and purpose of the steam drum • How steam-water separation is arranged in a typical marine water-tube boiler

💭 Think About

• Think about what part of the boiler needs the driest steam and why that would influence where a dry pipe is installed. • Consider which component of the boiler contains both steam and water together and needs internal fittings to help separate them. • Visualize a boiler cross‑section: where would you place a perforated pipe to draw off steam but leave most of the water behind?

✅ Before You Answer

• Identify which single component of the boiler actually has steam space above water (this is key to finding the dry pipe). • Make sure the option you choose is located where steam is collected from above the water line, not where it is being further heated. • Confirm that the dry pipe’s job is improving steam dryness before it leaves the drum, so it must be inside the component where separation happens.
