## Case studies

- [1 t/h hazelnut shell line, Türkiye — seasonal shell, campaign operation](https://furnace.huohualu.com/cases/hazelnut-shell-1tph-turkiye): A hazelnut processor with 4,000 t/year of shell that used to be sold as boiler fuel. The line runs in campaigns of 6–8 weeks rather than continuously, and was designed around that from the start.
- [2 t/h coconut shell line, Sumatra — 1,050 mg/g at 94% availability](https://furnace.huohualu.com/cases/coconut-shell-2tph-indonesia): A charcoal trader moving downstream into activated carbon. No carbonization on site, so the whole project was sized on purchased char quality — which turned out to be the deciding variable.
- [3 t/h palm kernel shell plant, Kalimantan — waste heat covers 46% of steam](https://furnace.huohualu.com/cases/pks-3tph-kalimantan): A palm oil group using its own shell output. The furnace was the easy part; the project was really about heat integration and ash control.

## Technical notes

- [Steam vs chemical activation: which route fits your feedstock](https://furnace.huohualu.com/resources/steam-vs-chemical-activation): Phosphoric acid gives higher yield at half the temperature. Steam costs more energy and returns a cleaner product. The choice is decided by your end market, not by the process.
- [How much coconut shell does one tonne of activated carbon need?](https://furnace.huohualu.com/resources/how-much-coconut-shell-per-tonne): 5.0–5.5 tonnes, and the range matters more than the average. Here is the full yield chain with the arithmetic you can check against your own supplier's numbers.
- [Rotary kiln or Slep furnace: choosing between 1 and 3 t/h](https://furnace.huohualu.com/resources/rotary-vs-slep-furnace): Both are continuous. Both use steam. The difference shows up in turn-down ratio, feed tolerance and how many machines you need to hit your tonnage.
