This work is dedicated to the determination of the particle emission from a commercially available bottom feed 5 kW pellet stove. Two-stage dilution was applied to provide the operational stability and conditioning of the sample. The analysis of particle emission was performed by means of the Electrical Low Pressure Impactor with 14 stages, able to separate particles from 0.006 to 10 µm. Measurements were carried out for several runs with nominal and part load regimes respectively at 5 and 2.5 kW. The study is focusing on the particle concentrations and their number size distributions as these factors have an important impact on atmospheric pollution and human health. The emission factors from different combustion cycles were in a range from 3.07×1014 to 2.44×1015 particles per kg (from 1.97×1013 to 1.57×1014 particles per MJ). The majority of measured particles were smaller than 1 µm. The particle distribution varied in different phases of combustion. The emission factors from different combustion cycles with included burnout phases were in a range from 2.53×1014 to 2.67×1015 particles per kg (from 1.62×1013 to 1.71×1014 particles per MJ).
