One of the less desirable characteristics of firetube boilers is the poor quality of steam they prouduce. This is due to the fact that there is insufficient room above the water level (in the steam space)to install any type of steam scrubbing equipment such as cyclone separatorss, corrugated scrubbers or even a dry pipe. It is for theis reason that steam generated from firetube boilers should not be utilitzed for steam turbine drives.
