In a coil-type forced circulation auxiliary water-tube boiler, _______________.

AI Explanation
The correct answer is A) steam demand response is comparatively rapid. In a coil-type forced circulation auxiliary water-tube boiler, the steam demand response is comparatively rapid. This is because the water circulation is forced through the coils by a pump, allowing for faster steam generation compared to natural circulation boilers. The rapid steam demand response is a key advantage of this boiler type. The other options are incorrect: B) is incorrect because steam is not recirculated through heating coils in this type of boiler. C) is incorrect because unevaporated feed water is not discharged through a skim tube in this boiler. D) is incorrect because the steam demand response is rapid, not slow.
