What anchors the blades and transmits their force to the shaft?

• A. Rotor
• B. Steam drum
• C. Diffusers
• D. Economizer

Answer: (A)

The correct choice refers to the rotor, which serves a crucial role in the operation of turbines or rotors where blades are utilized. The rotor is designed to anchor the blades securely, ensuring that they remain fixed in place while withstanding the forces generated during operation. When the blades are subjected to fluid flow, whether from steam, water, or air, they experience various forces that need to be effectively transferred to the rotor. This transfer of force to the rotor is vital, as it allows the kinetic energy from the fluid to be converted into mechanical energy, which is then transmitted to the shaft for work. In contrast, the other options serve different functions within a system. The steam drum is primarily responsible for separating steam from water in steam-generating systems, the diffusers function to change the pressure and velocity of the working fluid to enhance efficiency, and the economizer is used to preheat the feedwater entering the steam generator to improve the system's overall thermal efficiency. These components are essential for their respective roles but do not directly anchor the blades or transmit force to the shaft like the rotor does.
