Solid fuels combustion is rather complicated because there is always environment pollution by emissions, mainly by particulate matter. The efforts of heat sources manufacturers and also operators should be increase the effectivity of the combustion process with minimizing of emissions production. Nowadays it is possible effectively burn the biomass fuels in modern heat sources. The combustion process of biomass is influenced by many aspects. This work deals about these aspect that influence the combustion efficiency and emissions production of small heat source. Automatic small hot-water boiler for wood pellets with 18 kW heat power was used for the experiments. The effect of the amount, temperature and relative humidity of combustion air, fuel moisture and fuel feeding on heat power and production of carbon monoxide and nitrogen oxides has been determined. The experiments results show that these tested aspects have high impact on combustion process and environment pollution. The most significant aspect was fuel moisture while wit rising moisture the heat power of boiler significantly decreased and production of emissions increased.
