Abstract

Combustion is understood to be the oxidation of a fuel with the release of energy. Carbon (C) and hydrogen (H) are oxidized in the presence of Oxygen (O) to form carbon dioxide (CO2) and water (H2O), respectively.

Notes

  1. 1.

    According to prEN 14961-2, pellets for non-industrial utilization should have a minimum length 3.15 mm and maximally 40 mm, 1 % of the pellets being allowed to exceed this length limit up to a maximum of 45 mm.

  2. 2.

    The term "particulate matter" or "extra-fine particles" describes a complex mixture of solid and/or liquid organic and inorganic pollutants ejected into the air. The particles vary in size, composition and origin and are described by means of their particle size or aerodynamic diameter (PM means particulate matter) [21].

  3. 3.

    Aerosols are formed by the release of aerosol-forming components (relevant elements: K, Na, S, Cl, Zn, Pb) from the fuel and the subsequent formation of particles via nucleation of ash-forming vapors and by particle growth through condensation and agglomeration. The flue ash emissions from the complete combustion of biomass consist essentially of potassium sulphates, potassium chlorides and potassium carbonates (salts) [22].
