Downcomers - an overview | ScienceDirect Topics

Downcomers are tubes that start from the drum and lead water to furnace walls and boiler banks, see (Fig. 4.12 ). Downcomers can be divided to main downcomers and connecting tubes. It is customary that 2–5 large tubes go straight down from the drum. Often in the end of downcomers is a connecting header.
