Question 284Steam Plants - Assistant Engineer70% to pass
Large steam drums are not required in the design of a coil-type auxiliary water-tube boiler because _______________.
AI Explanation
The correct answer is A) steam and water are separated in the accumulator (flash chamber).
In a coil-type auxiliary water-tube boiler, the steam and water are separated in the accumulator (also called a flash chamber). This separation occurs as the steam-water mixture flashes into steam, leaving the water behind. This process eliminates the need for a large steam drum, as the steam is generated directly from the heated water coils without the requirement for a large water storage volume. The other answer choices are incorrect because they do not accurately describe the design and operation of a coil-type auxiliary water-tube boiler.
