276. Which characteristic of fuel oil is the most significant when determining the temperature to which the fuel oil must be heated for proper atomization?
Fuel oil viscosity directly influences atomization; heating reduces viscosity to achieve the optimal range for proper spray formation and combustion efficiency. Other properties like flash point, pour point, and specific gravity are relevant for safety and handling but do not dictate the required preheat temperature.
