What type of turbine allows steam to enter at the center and flow outward through two identical sets of stages?

• A. Single Flow
• B. Double Flow
• C. Radial Flow
• D. Axial Flow

Answer: (B)

The double flow turbine is designed to allow steam to enter at the center and flow outward through two identical sets of stages. This configuration effectively utilizes the steam's energy by splitting the flow, allowing for a balanced operation and enhanced efficiency. By having two sets of stages, the turbine can handle higher volumes of steam without increasing the overall size of the turbine, making it suitable for applications where space and weight are considerations. In contrast, a single flow turbine features a configuration where steam enters from one side and flows through one set of blades, which may limit the volume and efficiency compared to the double flow design. Radial flow turbines direct fluid from the center radially outward, but do not typically split the flow into two stages. Axial flow turbines move the steam along the axis of the turbine, which is a different operational principle altogether. The distinct design and operational efficiencies of the double flow turbine make it the correct answer in this context.
