Due to the problem of corrosion caused by acidic gases, there is now a trend toward using tetrafluoroethylene heat exchangers, and their use is increasing. Let’s clarify a few points first: 1. Price and cost issue: Metal heat exchangers have a high heat transfer coefficient, which requires a smaller area for heat exchange, but they are dense ； The tetrafluoroethylene heat exchanger has a low heat transfer coefficient and a large surface area, but it has a low density ； In contrast, the cost of tetrafluoroethylene heat exchangers is not necessarily higher than that of metal ones. 2. Corrosion resistance. There’s nothing else to say – tetrafluoroethylene is much better than metal heat exchangers. In the field of flue gas, a tetrafluoroethylene heat exchanger can easily last 10 years or more. All of the above are recognized conclusions; the use of tetrafluoroethylene heat exchangers is already a fact. Here is a design for a typical tetrafluoroethylene heat exchanger, which is already in successful operation. A service life of 15 years is no problem (Party A’s view).
