Sequence of Operation
The following “action-reaction” outline is provided to help you understand how the
equipment functions.
When the steam inlet valve is opened, steam flows into the jacket at a pressure determined
by the boiler system, or by the pressure reducing valve which serves the kettle. In the jacket
steam releases its heat to the kettle as it condenses into water. The steam trap allows
condensate (water) to leave the kettle while holding the steam in.
When the steam supply is shut off, condensation of the remaining steam produces a
vacuum in the jacket, but the check valve in the condensate return line keeps water from
flowing back into the jacket.
