What is the Principle of a Pure Steam Generator?
2 Answers
Pure steam generator principle is as follows: 1. Feed water is delivered to the decontamination column and the tube side of the heat exchanger by 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). 2. The low velocity of the steam and the height of the column remove any potentially impure water droplets under gravity. By adjusting the opening of the industrial steam inlet valve through a pneumatic regulator, the pure steam pressure can be maintained at a constant value set by the user, ranging between 0-3bar.
I am an engineer. A pure steam generator is a specialized device primarily used to produce high-purity steam, free from any minerals or contaminants, especially suitable for industries such as pharmaceutical and medical equipment sterilization. Its core principle involves heating and evaporating raw water, then removing impurities through multi-effect distillation or separation techniques—such as condensing steam into distilled water and then circulating it through multi-stage heat exchangers to ensure the steam reaches pure water standards. Key components of the equipment include the evaporator, heat exchange tubes, and control system: raw water is first heated into steam in the evaporator by a boiler, impurities are separated via centrifugation or filtration, and finally, pure steam is delivered to the production line. In daily operations, it is crucial to monitor water quality and perform maintenance to prevent scaling from affecting efficiency. Regularly inspecting safety valves and sensors is also essential to ensure stable operation under high pressure and temperature. The entire process requires precise control of temperature and time to avoid energy waste and potential risks. In modern applications, this not only ensures production process reliability but also complies with stringent sterile standards, significantly enhancing product safety.
