Question 108Steam Plants - 1st Asst/Chief

The correct answer is D) straight mechanical. The illustration SG-0022 depicts a simple, straight mechanical atomizer assembly, which is a common type of atomizer used in various burner systems. This type of atomizer relies on the mechanical force of the fuel pump to break the fuel into a fine mist, without the use of additional energy sources like rotary cups or steam. The other answer choices are incorrect because: A) a rotary cup type atomizer is a different design that uses a spinning cup to atomize the fuel; B) steam atomization is a distinct process not shown in the illustration; and C) a return flow type burner management system is a different configuration not depicted in the given illustration.
