Question 599Steam Plants - Assistant Engineer

The correct answer is C) binding wire. The use of binding wire is a common method for reducing turbine reaction blade vibration. Binding wire is wrapped around the turbine blades to provide additional support and damping, which helps to mitigate excessive vibration that can occur in the blades. This technique is widely used in the marine industry, including on U.S. Coast Guard vessels, to improve the reliability and performance of turbine-powered systems. The other options are incorrect because they do not directly address the issue of turbine blade vibration. Casing diaphragms (A) and casing seal strips (D) are used for different purposes, such as controlling leakage and maintaining proper clearances, while dummy pistons (B) are typically used in positive displacement engines, not turbines.
