Which advantage of steam atomization allows for operation in colder conditions?

The advantage of steam atomization that allows for operation in colder conditions is better combustion in a cold furnace. This method enhances the mixing of fuel and air, providing optimal combustion efficiency, even when the combustion environment is cold. When steam is used in the atomization process, it helps to create a finer fuel mist, which can achieve better atomization. This is essential in a cold environment where fuel might tend to be less effective in burning due to lower temperatures. The improved air-fuel mixing facilitated by steam atomization leads to a more complete combustion process, resulting in efficient operation regardless of temperature conditions.

Lower fuel viscosity, reduced pressure requirements, and improved air mixing are significant benefits of steam atomization as well, but they do not specifically address the challenges presented by colder operating conditions as effectively as the enhancement of combustion in a cold furnace does.
