According to the scheme in Fig. 1 c, two fans supplied air through two separated zones in the combustion unit. Primary air entered through the plenum module, directly initiating the thermal conversion of the fresh biomass, while secondary air entered above the fuel bed and was responsible for the complete reaction of the unburned species.

Biomass Combustion Technology -

Biomass combustion is a complex process that consists of consecutive heterogeneous and homogeneous reactions. The main process steps are drying, devolatilization, gasification, char combustion, and gas-phase oxidation. The time used for each reaction depends on the fuel size and properties, on temperature, and on combustion conditions.

In these burners the primary air which is pre-mixed with the gas is insufficient for complete combustion. Secondary air, usually drawn from the surrounding atmosphere, also enters the flame, diffusing inwards to complete the oxidation of the gas. If the theoretical mixture were used the flame propagation velocity would normally be impracticably high.
