Staging technologies (i.e., air-staging and fuel-staging) and flue gas recirculation are possible primary measures to reduce the NOx emission level from biomass combustion. LCA studies have shown that the main pollutant from wood combustion will be NOx, with an emission impact factor as high as 38.6%. SCR and SNCR are common secondary measures to reduce NOx emissions. Incomplete combustion of biomass will lead to carbon monoxide, hydrocarbons, particulate matter and polycyclic aromatic hydrocarbons, while complete combustion will lead to NOx and SOx emissions. the flue gas, to reduce the emission levels. Thus primary measures are dealing with the combustion zone and improvements to this area, while secondary measures look at the exit of combustion chamber, i.e. Primary measures are used to avoid creation of these emissions, while secondary measures remove the emissions from the exhaust gas. corrosion and fouling) To avoid emissions, both primary measures and secondary measures can be used. In addition to the three main elements: O, H and C as the major part, there are also some other minor or trace elements included in the biomass structure such as N, S, Cl and ash elements, contributing to emissions and operational problems (e.g. Thermochemical technology (including pyrolysis, gasification and combustion) is the most widely used technology to utilize biomass. To utilize biomass, the conversion pathway could be done in three different ways: thermochemical, biological and physical.
It can be material that has been taken from a primary production process (chip wood from forestry) or re-claimed material (such as used, clean untreated pallets, waste …).
