Question 742Steam Plants - Assistant Engineer

The correct answer is C) soot blowers. Auxiliary steam at full operating pressure is typically supplied from the boiler directly to the soot blowers. Soot blowers are devices used to remove accumulated soot and ash deposits from the boiler tubes, improving heat transfer and boiler efficiency. This direct steam supply to the soot blowers is a common arrangement in steam-powered vessels, including those operated by the US Coast Guard. The other options are incorrect because main air ejectors, distilling plants, and turbo-generators would not be the direct recipients of this high-pressure auxiliary steam from the boiler. These other systems may utilize steam, but not necessarily the full operating pressure directly from the boiler.
