Resumen de Particle emissions from biomass combustion in small combustors
Linda S. Johansson, Bo Leckner, Peter Sjövall, Claes J. Tullin
Literature data on particle emissions are compared with emissions from combustion of wood pellets and wood briquettes in commercial small-scale combustion devices: a pellet stove, two pellet burners and two smaller district heating boilers. The influence of operating parameters and fuel quality was investigated. Mass concentration, number concentration and number size distribution of particles were determined. The mass size distribution was analysed as well as the inorganic components. Gaseous compounds were recorded to give information about the combustion conditions. The mass concentrations of particles were between 34 and 20 mg Nm -3, increasing during unsatisfactory operation conditions.
