What is the principle of a pure steam generator?

[VonWyatt]

Pure steam generator principle is as follows: Feed water is delivered to the decontamination column and the tube side of the heat exchanger via a feed pump, with the liquid level controlled by a level gauge. Industrial steam or heating water enters the heat exchanger, heating the feed water to the evaporation temperature and creating a strong thermal circulation inside the two columns. Pure steam is then generated in the evaporator (decontamination column). The low velocity of the steam and the height of the column remove any potentially impure droplets under the force of gravity. By adjusting the opening of the industrial steam inlet valve through a pneumatic regulator, the pure steam pressure can be stably maintained at the user-set pressure value, ranging between 0-3 bar.
