A backflow burner (often used with backflow incense cones) is a special type of incense burner that creates a mesmerizing smoke “waterfall” effect. It works based on the density of the smoke and the design of the incense cone and burner. Here’s how it works:

🔥 How a Backflow Burner Works:

1. Special Backflow Incense Cones:

   • These cones are different from regular incense cones.

   • They have a small hollow tunnel running through the center with a hole at the bottom.

   • When lit, smoke is channeled downward through this tunnel.

2. Smoke is Heavier than Air:

   • The smoke produced by incense is cooler and denser than the surrounding air.

   • Instead of rising (like typical incense smoke), it flows downward due to gravity.

3. Burner Design:

   • The burner is designed with cascading paths (like waterfalls or steps).

   • The smoke flows from the hole in the cone down these paths, creating a flowing, mist-like effect.

4. Airflow & Placement:

   • Backflow burners need still air to work properly.

   • Drafts or strong airflow can disrupt the downward smoke trail.

🎯 Key Differences from Regular Incense Burners:

🧼 Tip: Cleaning Your Backflow Burner

• These burners can build up resin and oil residues from the smoke.

• Clean regularly with warm water and mild soap, or use rubbing alcohol for tougher stains.
