Renewable Energy Sources: LESSON 6. Biomass

The main combustion parameter is the excess air ratio (ì) that describes the ratio between the locally available and the stoichiometric amount of combustion air. For typical biomass, the combustion reaction can then be described by the following equation if fuel constituents such as N, K, Cl, etc., are neglected: CH 1.44 O 0.66 + ì1.03 (O 2
