Steam Boilers Summary
#Boilers are vessels that allow water in contained piping to be heated to steam by a heat source internal to the vessel. The water is heated to the boiling point. The resulting steam separates, and the water is heated again. Some boilers use the heat from combustion off-gasses to further heat the steam (superheat) and/or to preheat the feedwater.

#The following components were discussed:
1.The steam drum is where the steam is separated from the heated water.
2. Downcomers are the pipes in which the water from the steam drum travels to reach the bottom of the boiler.
3. Distribution headers are large pipe headers that carry the water from the downcomers to the risers.
4. Risers are the piping or tubes that form the combustion chamber enclosure. Water and steam run through the risers to be heated.
5. The combustion chamber is located at the bottom of the boiler and is where
the air and fuel mix and burn.
