Biochar is relatively non-flammable compared to raw biomass. This is due to its high carbon content and low volatile matter. These characteristics are a result of the pyrolysis process it undergoes.
4 Key Factors You Need to Know About Biochar's Flammability
1. Explanation of Pyrolysis and Flammability
Pyrolysis is a thermochemical process. It involves heating organic materials in the absence of oxygen. This process produces biochar, along with other products like biogas and bio-oil.
During pyrolysis, the organic material is subjected to high temperatures. This causes the decomposition of the material into its constituent parts.
This process is crucial in the production of biochar. It removes the volatile components (hydrogen and oxygen) from the biomass. This leaves behind a carbon-rich residue.
The removal of these volatile components reduces the flammability of the material.
2. Comparison with Other Fuels
The flammability of biochar can be compared to other carbon-rich materials like charcoal and coal. Charcoal has a heat value of 29–30 kJ/g, similar to coke and slightly lower than coal.
However, the key difference lies in the volatile matter content. Biochar, having undergone pyrolysis, has a much lower volatile matter content than raw biomass or even charcoal. This makes it less prone to spontaneous combustion.
3. Impact of Pyrolysis Temperature on Flammability
The temperature at which pyrolysis occurs significantly affects the flammability of the resulting biochar. Higher pyrolysis temperatures result in a harder, more brittle biochar.
This biochar does not catch fire until much higher temperatures (around 700 °C) are reached. This is in contrast to lower-grade charcoal produced at lower temperatures.
Lower-grade charcoal is softer and more prone to catching fire at lower temperatures (around 380 °C).
4. Conclusion
In summary, biochar is less flammable than raw biomass due to the pyrolysis process. This process removes volatile components and leaves a carbon-rich, stable material.
The specific conditions of pyrolysis, particularly the temperature, further influence the flammability of biochar. Higher temperatures generally produce a less flammable product.
This makes biochar a safer and more stable material for various applications. These include soil amendment and carbon sequestration, compared to raw biomass or lower-grade charcoals.
