Drying by fuel + energy recovery

[Imane]

Hello,
I am called to reduce the consumption of fuel used for drying fertilizers. I thought of making an air preheater before the fuel combustion chamber to reduce the amount of fuel used.
Or I want to recover the heat lost during the cooling of the finished products.
Can you help me know the methodology I need to adopt to get my work done?

1. set orders of magnitude
2. find ideas
3. quantify the implementation and exploitation of these ideas (costs and gains)
4. to choose
5. make

What would you think of a cycle drying

temperature control in a closed circuit,
we re-inject hot air directly
which requires little energy and improves heat exchange

to heat fertilizer, there is inertia,
and during it and warming up, whether the air is dry or wet does not matter


opening of the circuit to evacuate the humid air

And, AMHA, one thing must underpin all the study: security

fertilizers, yes, but what fertilizers: some are explosive, right?

Hello,
I'm also interested to know what kind of fertilizer it is (nitrates?), and also how much fuel it consumes for what result?

if you want an answer, you have to describe your current drying process, because there is no universal solution to save energy.

as there is a multitude of different drying process give generality will be useless
