Selection of solid-solid heat exchangers
Thread Content
The temperature of the high-temperature mineral powder (product) is 600°C; how can this heat be exchanged with the mineral powder at room temperature? Are there any devices for direct solid-solid heat exchange?

Thermal power generation is also a possibility to consider. It would be best to consider a method that recovers heat more thoroughly. Utilization should come second.
After some thought, I wondered if it would be possible to use a drum method
I’m talking about heat exchange – is it possible to preheat the raw mineral powder? Some people say that heat transfer can occur directly through the tube wall, with the hot material flowing inside the tubes and the raw mineral powder flowing inside the casing, and that forced heat transfer can be achieved using screw conveyors. Is that possible?
Are there any good methods for solid-solid heat transfer? Direct heat exchange, without an intermediate medium
