A steam drum is a standard feature of a water-tube boiler. It is a reservoir of water/steam at the top end of the water tubes. The drum stores the steam generated in the water tubes and acts as a phase-separator for the steam/water mixture. The difference in densities between hot and cold water helps in the accumulation of the "hotter"-water/and saturated-steam into the steam-drum.

Of the supernova burgeoning over the barn,
Lampshine blurred in the steam of beasts, the spirit’s right
Oasis, light incarnate.”

As his corse to the rampart we hurried;”
