Question 1Steam Plants - 1st Asst/Chief

The correct answer is A) stationary air foil or blade cone. In an air register assembly, the majority of air passes through the stationary air foil or blade cone. This is because the air foil or blade cone is the primary component that regulates and distributes the airflow within the assembly. The air foil or blade cone is designed to efficiently channel and control the airflow, ensuring the majority of the air passes through this component rather than the other parts of the assembly. The other options are incorrect because the distance piece is not the primary pathway for the majority of air (B), the diffuser or impeller are not the main components for airflow (C), and the atomizer assembly is not responsible for the majority of air passage (D).
