What type of deposits might occur if oil spray contacts the walls of the combustion chamber?

Water deposits
Salt deposits
Carbon deposits
Mineral deposits

The correct answer is: Carbon deposits

When oil spray contacts the walls of the combustion chamber, it can lead to the formation of carbon deposits. This occurs due to incomplete combustion of the oil, which often happens when the mixture of fuel and air is not optimal. In such conditions, the hydrocarbons in the oil do not burn entirely, resulting in the production of soot and carbon. These carbon deposits can accumulate on the surfaces of the combustion chamber and other components, potentially affecting the efficiency of the boiler operation. Accumulation of carbon can also lead to increased maintenance requirements, as they need to be removed periodically to ensure the combustion system functions effectively. Understanding this process is important for maintaining a well-operating low pressure boiler.
