Question 557Steam Plants - Assistant Engineer70% to pass
A turbine assembly in which steam flows in series through a high-pressure turbine and then on to a low-pressure turbine, with both turbines driving a common reduction gear through separate shafts, is classified as _______________.
AI Explanation
The correct answer is D) cross compound.
In a cross-compound turbine assembly, the steam flows in series through a high-pressure turbine and then on to a low-pressure turbine, with both turbines driving a common reduction gear through separate shafts. This configuration is classified as a cross-compound turbine arrangement.
The other answer choices are incorrect because:
A) Tandem compound refers to a single turbine shaft with both high-pressure and low-pressure turbine sections.
B) Dual series is not a standard classification for turbine arrangements.
C) Tandem, double flow refers to a single turbine shaft with both high-pressure and low-pressure sections, but with the steam flowing in parallel through the sections.
