Question 100Steam Plants - 1st Asst/Chief

The correct answer is C) mixing chamber. In a steam assist atomizer, the fuel oil/steam mix takes place entirely within the mixing chamber. The mixing chamber is the area where the fuel oil and steam are combined and thoroughly mixed before being expelled from the atomizer. This thorough mixing within the mixing chamber is what allows for proper atomization of the fuel oil. The other answer options are incorrect because they do not accurately describe where the fuel oil/steam mixing occurs. The fuel oil swirlers, whirling chamber, and tangential slots are other components of the atomizer, but they are not where the final mixing of the fuel and steam takes place.
