Question 528Steam Plants - Assistant Engineer
70% to passWhen a turbine rotor is not rotating during maneuvering, the heat tends to be concentrated at the _______________.
Atop of the turbine
Bexhaust trunk
Cturbine bleed lines
Dcasing joints
AI Explanation
The correct answer is A) top of the turbine. When a turbine rotor is not rotating during maneuvering, the heat tends to be concentrated at the top of the turbine. This is because the lack of rotation prevents the heat from being evenly distributed throughout the turbine. Instead, the heat accumulates at the top of the turbine, where it is not being circulated away by the rotating blades. The other answer choices are incorrect because they do not accurately describe where the heat would be concentrated in a non-rotating turbine. The exhaust trunk, turbine bleed lines, and casing joints are not the primary areas where heat would accumulate in this scenario.
