Which of the significant combustible elements of fuel oil is a major source of boiler corrosion?

AHydrogen
BOxygen
CCarbon
DSulfur
AI Explanation

The correct answer is D) Sulfur. Sulfur is a major source of boiler corrosion in fuel oil. When fuel oil containing sulfur is burned, the sulfur can form sulfuric acid, which can lead to corrosion of the boiler and other components. This is a well-known issue in the maritime industry, and the sulfur content of fuel oil is a critical factor that must be monitored and controlled to prevent boiler damage and ensure the safe operation of vessels. The other options, such as hydrogen, oxygen, and carbon, while important combustible elements of fuel oil, are not directly responsible for the corrosive effects that can damage boilers.
