Where is the steam space located in a vertical firetube boiler?

In a vertical firetube boiler, the steam space is located at the top of the shell. This design is critical because steam naturally rises, allowing for efficient separation of steam from the water. The upward movement of steam leads to the collection of steam at the top, where it can be accessed for use in the system.

Having the steam space at the top also aids in maintaining pressure throughout the boiler, as steam accumulates while the water remains below. This positioning ensures that steam can be withdrawn without disturbing the water level significantly, helping maintain optimal operating conditions. The efficiency of heat exchange in a vertical firetube boiler is enhanced by this configuration, promoting better steam generation and thermal performance.
