Comparison of pollutant emission indicators during virginia mallow pellets and wood pellets combustion – a case study

Joanna Szyszlak-Bargłowicz

Abstract


Ecological aspects and environmental threats indicate that wood pallets should be used mainly in low-power furnaces for heating households. Because burners and fuel feeding systems were adjusted to wood pellets, pellets from other types of biomass, including the waste biomass in systems which enable a controlled process, should be considered. Taking into consideration the possibility of use of Virginia mallow pellets for supply of low-power furnaces as alternative fuel to wood pellets, the objective of the research was to determine and compare indicators of emission of CO, NOX, SO2, 16 WWA including B(a)P, TOC and dust during combustion of these two biofuels. Emission indicators were referred to the mass of combusted biofuel and the amount of the obtained energy. Installation used in the research was a typical installation used for heating of one-family houses and designed for combustion of pellets. CO and dust emission indicators for Virginia mallow pellets were considerably higher in comparison to the indicators for wood pellets. Emission indicators of the remaining pollutions (SO2, NOX, TOC, dust, WWA, B(a)P) were similar to both tested biofuels.
