🔍 Key Concepts

• Difference between fire-tube and water-tube boiler gas paths • Where soot forms and why soot blowers are needed • How often soot accumulates in high‑capacity, high‑gas‑velocity boilers

💭 Think About

• On which boiler type do hot combustion gases pass through many small tubes at relatively high velocity, making soot deposits more likely on heating surfaces? • Which boiler types would produce little to no stack soot because they do not use a flame or large gas passages? • Between natural‑circulation and forced‑circulation water‑tube boilers, which is more common as a main/auxiliary boiler on larger ships with heavy‑fuel firing?

✅ Before You Answer

• Identify which options actually have combustion gas passages where soot can build up • Eliminate any boiler type where heat is generated electrically rather than by burning fuel • Compare which remaining boiler design is used for larger outputs and dirtier fuels, where routine soot blowing is standard practice
