Asteam demand response is comparatively rapid
Bsteam is recirculated through heating coils in the boiler
Cunevaporated feed water is discharged through the skim tube
Dsteam demand response is slow
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.
