Emissions & U.S. Compliance
Permitting a roaster in the U.S. is mostly about smoke. Here is how we help you pass.
Most U.S. roasteries above ~1 kg need some form of emissions control to satisfy their local air-quality district and fire code. Yoshan supplies the abatement equipment matched to your roaster and your jurisdiction.
Afterburner vs. ESP — Which Do You Need?
| Thermal Afterburner | ESP Smoke Filter | |
|---|---|---|
| How it works | Combusts smoke/VOCs at 200–1,000°C | Electrostatically captures 95%+ particulate |
| Best for | Strict VOC/odor districts (e.g. CA AQMDs) | Particulate limits, residential-adjacent |
| Running cost | Higher (burns gas) | Lower (electric) |
| Roaster size | 1 kg – 300 kg | 1 kg – 300 kg |
What U.S. Permitting Usually Involves
- Local air district permit — many districts require an afterburner or equivalent above a roast-capacity threshold
- NFPA 86 — fire code for ovens/furnaces; covers gas trains, purge and safety interlocks
- Mechanical / ventilation permit — exhaust ducting and make-up air
- Gas connection — NG meter upsize or propane tank sizing
We are a manufacturer, not a permitting consultant — but we have shipped to 30+ countries and will configure the burner, gas train and abatement so your local mechanical engineer has what they need. Tell us your city and we’ll advise on the right setup.
