steam-out nozzle

[Jens12]

Please can somebody me explain what a "steam-out nozzle" is ? Is it the inlet of the steam or is it an outlet ?
The question came up during checking a vessel data sheet with heating coils.

Sounds to me like it would be a steam outlet nozzle. In other words, steam flows out or exits the pressure retaining item thru this nozzle.

This may not be much help but:

I see "steam out nozzles" specified reqularly on S&T exch, they come in pairs, one on each process nozzle (inlet/outlet) and are blinded. They may be on one or both sides of the exchanger (shell and/or tube) depending on the process. They are usually small 2"-3". I get the idea they are used for periodic cleaning of the exchanger, using steam.

A steam-out nozzle is used for steaming out (cleaning) the vessel. So the steam-out nozzle is an inlet and there should be a drain on the vessel to drain the condensate. The coil is for heating and is a different component altogether.

Steam out nozzles are for cleaning and making gasfree of vessels, heatexchangers etc. The steam is for displacing the product, normally throug a drain (low points), and the gas through the vents (high points). Probably in this case, the steam out connections are on the shell (vessel) side. In the petrochemical industry you cannot open a vessel to do maintenance or inspection if it is not thoroughly steamed out and gasfreed because, heat, flamable gases and oxygen is an explosive combination.
