Clean steam generator principle

The clean steam generator uses industrial steam to heat pure water and generates clean steam through secondary evaporation. It controls the quality of the pure water and uses a well-designed and manufactured clean steam generator and delivery system to ensure the steam entering the steam equipment. quality to meet the needs of the production process.

A typical clean steam generator, an instantaneous clean steam generator, refers to the principle of a pure steam generator in the pharmaceutical industry. After industrial steam heats pure water, the pure water heated to a saturated state is transported to a flash tank for depressurization and evaporation. . Since this kind of clean steam generator has no heat storage capacity, load fluctuations in the use of clean steam can easily cause the outlet steam to contain water, causing secondary pollution.

In applications with load fluctuations, the pressure of clean steam will also fluctuate greatly. Therefore, in strict applications, industrial steam is generally not controlled and equipment selection is increased to overcome this shortcoming. The operating cost of this type of clean steam generator is relatively high, and the consumption ratio of industrial steam to clean steam is basically 1.4:1. Instantaneous clean steam generators have higher supporting requirements and higher pure water consumption. The principle of the clean steam generator is suitable for demanding clean steam applications.

Another type of clean steam generator is based on the principles of reboilers and industrial boilers. Pure water is transported to a volumetric heat exchanger and heated by the industrial steam in the heating tube, causing bubbles to evaporate away from the liquid surface and produce clean steam. This kind of clean steam generator has better heat storage capacity and load regulation. However, precisely because of its heat storage capacity, it means that when the bubbles detach from the dirty boiler water, they will inevitably form steam and water, leading to the pollution of clean steam.
