Possible materials used fot the CCG® process
Ash-containing solid or liquid fuels, gases as a fuel additive
Demands on the ingredient
- Minimum content of ash
- Suitable ash composition (melting behavior, viscosity)
Addition in the solid fuel
- Drying to the removal of surface moisture (coal <2%, lignite <8 .12%)
Almost all types of coal can be used, from lignite to anthracite coal. Also the use of ash-rich coal is possible. The method is also suitable for salt coal, which is rarely used so far.
This is easily used in a mixture with coal or alone after addition of a minimum amount of ash.
By thermal treatment of biomass under exclusion of air at 250 to 300 ° C (pyrolysis) their fuel properties improve significantly. The torrefied biomass has a porous, carbon-like structure and may be ground as coal and mixed with the main fuel.
Other ingredients can be:
Heavy oil, bitumen, organic solvent, gas, organic waste
