-
AA fire-tube boiler occupies less space than a water-tube boiler, for a given power.
-
BSteam at high pressure and in large quantities can be produced with a simple vertical boiler.
-
CA simple vertical boiler has one fire tube.
-
DAll of the above
Answer
Correct Answer: A simple vertical boiler has one fire tube.
Explanation
Verification
- (a) Incorrect: For the same capacity, water-tube boilers typically occupy less space and hold less water than fire-tube units.
- (b) Incorrect: Simple vertical boilers are low capacity, low pressure units.
- (c) Correct: The classic simple vertical boiler has a single, central fire (flue) tube within the vertical shell (distinct from the vertical cross-tube type that adds cross tubes).
Final AnswerA simple vertical boiler has one fire tube.
