Boilers - EnggCyclopedia

Risers are pipes leading from the bottom to the top of the boiler. Water and steam generated in the combustion zone, runs through the risers up to the steam drum. Steam is separated in steam drum and water sent to distribution header through downcomers and the cycle is repeated.

(PDF) THERMAL FATIGUE FAILURE IN BED

Changes from design temperature profile When the boiler is overloaded, the flue gas flow is more. The heat pick-up pattern at various zone changes. When there is high excess air operation, the heat pick-up pattern changes. This also affects the circulation as the rear set of bank tubes may start steaming at times when the feed water flow is less.

Downcomers - an overview | ScienceDirect Topics

Esa Kari Vakkilainen, in Steam Generation from Biomass, 2017. 4.6.1 Downcomers and Dividers. 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.
