Multiloop control of a drum boiler - ScienceDirect

2014/5/1 · A schematic picture of a typical drum boiler is in Fig. 6. The water to be evaporated is added to a drum from which it goes down through the downcomers located outside of the firebox. The water then goes into the risers located in the hottest part of the furnace where it evaporates, and the steam rises and flows back up to the drum.
