Moisture Content

[5-10%]

The higher the water content, the lower the energy content. With a very high water content (>15%) there is a risk of biological decomposition.

Ash Content

[0.2-3%]

A higher content indicates content of foreign material (additives, dirt, other waste materials and so on).

A higher content leads to a risk of slagging (see deformation temperature).

Pellets made of tropical hardwood have higher ash content than coniferous softwood.

Ash Deformation Temperature

[1200-1500 ℃]

At lower temperatures there is a potential risk of slagging and/or formation of a coating (depending on operating conditions). At higher ash deformation temperatures there will be less slagging and less physical and chemical deformation of the ashes.

Calorific Value

[10-18.6 MJ/kg]

The gross calorific value is the total energy content released when a fuel is burnt in air, and includes the heat of condensation of water in the combustion products. Thus, it represents the maximum amount of energy potentially recoverable from a given biomass source.

Higher values result in better combustion properties and better economy.
