D250 tonnes/h
Answer
Correct Answer: 135 tonnes/h
Explanation
ConceptThe Benson boiler is a once-through, high-pressure (often supercritical) water-tube boiler. Standard objective-type references commonly quote a typical steaming capacity around 135 tonnes per hour for benchmark problems.
NotesAlthough practical designs may span a wide range, 135 t/h is the widely accepted figure for textbook MCQs.
Final Answer135 tonnes/h
