Low ash, long burning time, low smoke and high fixed carbon are common quality requirements for BBQ, coconut and shisha charcoal.
However, one common misunderstanding is that changing the binder alone can control all of these characteristics.
What Mainly Affects Ash Content?
Final ash content can be affected by:
Charcoal raw material
Mineral content
Carbonization quality
Binder composition
Other materials in the formulation
What Affects Burning Time?
Burning duration can be influenced by:
Fixed carbon
Briquette density
Shape and size
Airflow
Moisture
Raw material quality
What Is the Main Role of Binder?
The main purpose of charcoal briquette binder is to improve:
Particle bonding
Briquette forming
Mechanical strength
Crack resistance
Powder resistance
Handling stability
Test the Finished Briquette
Low ash, long burning and low smoke should be measured using the finished charcoal briquette, not judged from the binder alone.
This helps manufacturers develop a more stable production formula and avoid unrealistic product claims.
