Flash steam

admin — Wed, 18 May 2011 19:25:42 +0000

Flash steam – steam generated by the condensate when the pressure required to maintain the condensate above its boiling temperature is suddenly reduced.

Wet steam

admin — Wed, 18 May 2011 19:24:51 +0000

Wet steam, wet saturated steam – saturated steam, but still in the presence of water’s liquid phase. When the boiler sends through the piping saturated steam containing droplets of water, we speak of entrainment. It should be noted that the expression “wet saturated steam” doesn’t describe a physical state of steam, but rather a special case of saturated steam.

Upstream

Upstream – part of a steam system located before a specified location.

Thermal water hammer

admin — Wed, 18 May 2011 19:23:15 +0000

Thermal water hammer – water hammer caused when a bubble of hot steam encounters cold condensate. The steam bubble condenses rapidly, causing a vacuum in which the condensate irrupts, making a loud noise.

Temperature profile

Temperature profile, temperature gradient – graphic representation, as a function of time, of temperature measured at a specific location in a stream system.

Superheated steam

admin — Wed, 18 May 2011 19:21:45 +0000

Superheated steam – steam that was brought at a temperature above the saturation point. Superheated steam cannot exist in the presence of water, it consequently is always 100% dry.

Steam trap

Steam trap – device that automatically purges the condensate generated in a heat exchanger or a vessel containing steam, while keeping the steam from escaping.

Sightglass

Sightglass – transparent section in a pipe or on the wall of a tank, that make it possible to visualize the level or the flow of a liquid.

Separator

Separator – vessel that collects the blow-through steam and the condensate coming out of a rotary dryer. The condensate accumulates at the bottom and the steam rises to the top part of the separator.

Sensible heat

Sensible heat – heat stored or released by water following a change in temperature not accompanied by a change of phase.
