I would appreciate the guidance of experts; I’m looking to choose a heat exchanger
Thread Content
The inlet temperature of the heat exchanger is 300–400°C; the gas contains about 10–15% hydrogen chloride, along with a small amount of dust, with the rest being air. Since I want to use a bag filter to remove the dust, I am considering changing the heat exchanger. Which type of heat exchanger would be suitable in this case? industrially

The problem now is that the cooling plan depends on whether you have a place to utilize this heat. It’s best to make use of it. Additionally: 1. Using a water heat exchanger results in the smallest size and lowest investment for the heat exchanger, but it consumes circulating water. It would be even better to be able to heat the boiler water or other water as well (heat recovery) ； 2. Cooling is achieved using air; the heat exchanger is large and requires significant investment, but air is free ； With that approach, there is no technical difficulty in terms of the heat exchanger itself.
It is not clear what specific process is being used, whether that process is suitable for heat recovery, and it is also unknown whether the gas flow rate is high or low. Let’s guess: given the need for large capacity and heat recovery, would a regenerative gas-to-gas heat exchanger be a good choice? If the capacity is low and heat recovery is not intended, consider an air cooler?
Tubular type is also okay; it depends on the medium on the other side – the tubular type offers better safety features
A heat pipe heat exchanger can be used; it has a compact structure
Your answer is quite professional; I support it
The plate type is okay, but why GGH?
A heat exchanger with media on both sides, GAS GAS, abbreviated as GGH. Same as the abbreviation forAPH
That’s what I’m talking about. Regarding LZ’s question: is it suitable for air cooling?
