OMPOSITION

OF

THE

FUEL

Knowledge of the fuel composition forms the basis for the
combustion calculation and the treatment of operating issues
relating to firing technology. In addition to combustible substances,
the fuels also contain varying amounts of non-combustible, or “inert”
components.

With an increasing ratio of inert components, the calorific value
drops considerably, the combustion quality deteriorates, and the CO
emission and the amount of ash and cinder dirt on the heating
surfaces is increased.
