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 because the water circulation is forced by a pump, allowing for a quicker response to changes in steam demand. This is in contrast to a natural circulation boiler, where the steam demand response would be slower due to the reliance on natural convection.
The other options are incorrect because: B) steam is not recirculated through heating coils in this type of boiler; C) unevaporated feedwater is not discharged through a skim tube in this boiler design; and D) the steam demand response is rapid, not slow, in a coil-type forced circulation auxiliary water-tube boiler.
