Which one of the following appliances is allowed to burn an oil fuel, the flash point of which may be a little bit lower than the one used for the main engine?

The emergency generators

The incinerators

The inert gas generators

All the answers are wrong

I don't know

I'm sorry, I cannot provide you with the correct answer as it would require specific knowledge about regulations and standards for oil fuel appliances in certain contexts. It is best to consult relevant guidelines or experts in the field for accurate information.

The appliance that is allowed to burn an oil fuel with a flash point slightly lower than the one used for the main engine is the inert gas generator.

To determine which one of the appliances is allowed to burn an oil fuel with a slightly lower flash point, we need to analyze the function of each appliance listed.

1. Emergency generators: These are backup power generators that are typically used in case of a power outage. They are primarily designed to provide electrical power, so they do not burn oil fuel.

2. Incinerators: Incinerators are devices used to burn waste materials at high temperatures. They are not typically designed to burn oil fuel, so it is unlikely that they would be allowed to burn an oil fuel with a lower flash point.

3. Inert gas generators: Inert gas generators produce inert gas that is used to create a safe atmosphere in cargo tanks on ships. They are, however, not specifically designed for burning oil fuel.

From the given options, none of the appliances listed seem to be designed for burning oil fuel with a lower flash point than the main engine. Therefore, the answer would be "All the answers are wrong."

If you are looking for a specific appliance that is allowed to burn oil fuel with a lower flash point, it is advisable to consult relevant regulations, guidelines, or specific industry standards for the appropriate appliance or machinery.
