Miscanthus and its issues with combustion and corrosive nature.

Calorific value of wood and miscanthus per kg, is almost identical, but due to the density twice the storage and logistics costs.
Ash content 6-7 times higher than in wood with bark
Ash melting point below 1000 ° C and therefore problems with clinker development. Nitrogen (N) is almost completely converted to NOx; as it is not bound in the ash.
Fraction of potassium (K) reduces the ash melting point and promotes the release of very fine dust particles (<0.1 microns).
The sulphur (S) is converted to SO 2, causing corrosion.
