“…Pellets are therefore preferable to logs -while presenting a similar density they allow automated fuel supply (the combustion chamber does not need to be opened for feeding) which translates into higher temperature in the combustion chamber and therefore much lower carbon monoxide concentration as compared to wood log firing (Fiedler, 2004;Johansson et al, 2004). Over the last decade, wood pellets have become more popular and are often introduced to the heating boilers instead of wood logs (Boman, et al, 2003). They are especially common in Sweden, where they replaced fuel oil furnaces due to oil prices going up in the last decade.…”

The impact of the fuel feeding mode (continuous or periodic with different stand-by/operation time ratios) on carbon monoxide (CO) and nitrogen oxides (NO, NOx) concentration values in the flue gas was analysed for coniferous wood pellet firing. Experiments were performed in a 25 kW water boiler equipped with an over-fed wood pellet furnace located in a full scale heat station simulating real-life conditions. Influence of oxygen concentration and temperature in the combustion chamber on carbon monoxide and nitrogen oxide concentrations was presented in diagrams. Dust and hydrocarbon concentrations were also monitored. It was concluded that the commonly used periodic fuel supply does not necessarily cause a significant increase of carbon monoxide concentration, as compared to the continuous fuel feeding mode. Continuous fuel supply can even induce higher carbon monoxide concentrations when fuel mass stream is not chosen properly. Each time new fuel type is used in a specific furnace, one should perform experiments to determine the adequate settings (stand-by/operation time ratio, fuel mass streams, air stream) to obtain the optimal, lowest possible emission for a certain boiler heat output.

“…The pellets are produced mainly from sawdust and wood shavings. Although the emissions are much lower than those from traditional firewood burning, they are important to characterise because pellet burners and stoves are heating options in urban areas [3]. Emission data for a wide range of organic compounds in smoke from wood burning in residential fireplaces are available for comparisons [4][5][6].…”

Samples of smoke from laboratory burning of commercial sawdust-based softwood pellets were analysed by gas chromatography on an aluminium oxide column. Flaming burning was very efficient. Significant emitted hydrocarbons were methane, quantitatively followed by ethene and lower proportions of ethane, ethyne and propene. The even lower hydrocarbon emissions from final glowing combustion were strikingly different with ethyne and benzene as the only prominent non-methane hydrocarbons. Smouldering combustion caused much higher hydrocarbon concentrations. Prominent non-methane compounds were furan and ethene from initial smouldering, and ethane, ethene and benzene from after-flame smouldering. The large differences in the proportions of specific hydrocarbons should be considered in evaluations of emissions from residential burning of pellets, with respect to combustion technology and impact on environment and health.

“…Renewable and sustainable source of energy are promoting all over the world due to net zero emission of carbon credits (Schobert, 2013, Demirbaş, 2001, Vassilev et al, 2010. The wood pellet industry is growing for energy applications (Wilson et al, 2011, Badger and Fransham, 2006, Boman et al, 2003, Kumar et al, 2003, Tillman, 2000, Saeed et al, 2017. A huge stock of wood pellets is used as fuel for boilers.…”
