Question 46General Subjects - 1st Asst/Chief

The correct answer is A) turbine extraction line. The steam supply for the operation of the low pressure evaporators is typically obtained directly from the turbine extraction line. This is because the turbine extraction line provides a source of lower pressure steam, which is suitable for the operation of the low pressure evaporators. The other options are incorrect because: B) The turbo-generator steam supply line would provide high pressure steam, which is not suitable for the low pressure evaporators. C) The main steam line would also provide high pressure steam, which is not suitable for the low pressure evaporators. D) The air ejector exhaust line would not provide a suitable steam supply for the low pressure evaporators.
