What is the result of water in the fuel oil or using the wrong grade?

Ignition failure
Puff back
Improper atomization
Vapor condensation

The correct answer is: Improper atomization

Using the wrong grade of fuel oil or having water present in the fuel can significantly impact the combustion process in a low-pressure boiler. When fuel oil is not properly atomized, it does not mix efficiently with air, which is necessary for combustion. Proper atomization is crucial for achieving the desired flame quality and combustion efficiency. If the fuel oil is too viscous or contaminated with water, it can lead to improper fuel droplet sizes being produced, which ultimately results in incomplete combustion, and thus reduced efficiency and potential operational issues. Inadequate atomization can also lead to other complications, such as increased emissions and the potential for fuel to accumulate in the combustion chamber, creating more risks. Therefore, ensuring that the correct grade of fuel oil is used, and that it is free from contaminants like water, is essential to maintaining the proper function of the boiler and its safety.
