Biomass continuous torrefaction and carbonisation plant

Testing of CFTC

Flash torrefier and carbonizer system

Torrefaction is a thermal process to convert biomass into a coal-like material

Advantages:

• better fuel characteristics than the original biomass. 
• more brittle, making grinding easier and less energy intensive. 
• storage of the torrefied material can be substantially simplified since biological degradation and water uptake is minimized

Process:

Heating of biomass in the absence of oxygen to a temperature of typically 200 to 400°C

Products:

- solid, torrefied biomass

- combustible gas (utilised to provide heat to the process)

CFTC100:   

CFTC100 is continuous flash torrefier and carbonizer system with capacity ~ 100kg/h 

It consists of:-

• feeder: biomass feeding
• reactor: where biomass is converted into torrefied material and a combustible gas  
• cooling: the torrefaction product is highly flammable, necessitating the need for a cooling system
• heat recovery:where the combustible gas recover to heat outer reactor
• scrubber: scrub the volatile and vapour from the reactor

- heat required is generated by combustion (example diesel burner)
- the hot flue gas heat the screw along the center 
- heated screw indirectly heat the biomass
- waste heat that left the reactor recover along the outer wall of the reactor
- volatile and vapor produce can be directly burn in the separate combustor (for drying purpose) or scrub

Products:
Depends on the applied process conditions (example operating temperature and residence time), at high temperatures a completely carbonised material is produced (charcoal)

We are actively developed torrefier system for application of producing biochar (charcoal)
The pilot plant was built for our client (~ 100 - 150 kg/hr input)
The size is ready for up-scaling to meet the industrial request
