SYSTEMS FOR FLUE GASES TREATMENT AT THE COMBUSTION OF (AGRICULTURAL) BIOMASS
Апстракт
Biomass combustion has many advantages compared to fossil fuels due to reduction
of carbon dioxide emissions, but several issues are present during biomass combustion. One that
must always be considered is emission of nitrogen oxides (NOx), which have significant impact on
the environment and health. At biomass combustion, main mechanism responsible for NOx
emission is oxidation of fuel-bound nitrogen. Increased NOx emissions are particularly present at
agricultural biomass combustion, due to its increased nitrogen content, which is further expressed
by the use of nitrogen fertilizer. Denitrification methods are classified as pre-combustion,
combustion control and post-combustion (flue gas treatment) methods. Aim of this paper is to
provide insight in different flue gas denitrification methods (DeNOx measures) from the review of
existing literature, with emphasis on post-combustion methods, since they have higher efficiency.
Also, pre-combustion and combustion control methods... at agricultural biomass combustion often
do not provide reduction below emission standards. Selective catalytic (SCR) and selective noncatalytic
reduction (SNCR), wet scrubbing, adsorption, electron beam, electrochemical method,
non-thermal plasma and microbial approach were considered. For each method, mechanism of
NOx reduction is given and discussed, alongside with efficiency that could be achieved. Overall
comparison of advantages and disadvantages for these methods is provided. Further research of
denitrification and optimization of described methods, to overcome NOx emission problem is
required. Application of these methods in commercial use and increasing their efficiency, while
solving cost and methods disadvantages, is key for biomass to be used as a renewable energy
source and fossil fuel replacement.
