One advantage of a triple-effect low pressure submerged tube distilling plant over a double-effect unit is __________.

🔍 Key Concepts

• Distilling plant "effects" – how adding more effects (stages) changes steam usage and heat recovery • Evaporator efficiency – fresh water output compared to steam/heat energy input • Relationship between number of effects and scale/corrosion versus thermal performance

💭 Think About

• How does using the vapor from one stage as the heating medium for the next stage affect overall heat economy? • If you add another effect (going from double to triple), which characteristic is MOST directly improved: water quality, scaling tendency, corrosion resistance, or heat/steam utilization? • Which of the listed choices is typically controlled more by water treatment and materials selection than by the number of effects?

✅ Before You Answer

• Identify which option is most clearly tied to heat recovery and energy economy. • Ask whether increasing the number of effects by itself directly changes water purity, or if that is more dependent on design and operating practices. • Consider whether scale formation and corrosion are primarily chemical/water-treatment issues or inherent to the number of effects.
