What is one benefit of cleaner burning of residual fuel in steam atomization?

Lower emissions are a significant benefit of cleaner burning of residual fuel in steam atomization. This process helps to optimize the combustion of fuel by mixing steam with the fuel, which enhances the atomization and leads to more complete combustion. As a result, it reduces the amount of unburned hydrocarbons that are released into the atmosphere. This is especially important in meeting environmental regulations and standards, as it contributes to better air quality and reduced environmental impact.

The other options don't directly relate to the advantages of cleaner burning. Higher fuel costs could stem from various factors in the energy market but are not a direct benefit of improved combustion efficiency. Increased downtime is generally a negative aspect of any operation and doesn't align with the benefits sought from cleaner burning practices. Greater energy consumption would indicate inefficiency rather than an advantage, as cleaner burning typically aims to maximize energy efficiency and minimize waste.
