Question 152Steam Plants - Assistant Engineer

The correct answer is B) straight mechanical. The illustration SG-0022 depicts a simple straight mechanical atomizer, which is a common type of atomizer used in burner systems. This type of atomizer uses the mechanical force of the fuel to break it up into a fine spray, without the need for additional pressurized air or steam. The straight mechanical design is a basic and reliable atomizer configuration, making it suitable for a variety of burner applications. The other answer choices are incorrect because: A) return flow burners use a different type of atomizer, C) rotary cup atomizers have a different internal design, and D) variable load steam atomization is a separate atomizer technology not shown in the illustration.
