Aspects Affecting Emission Production from Small Heat Sources

Achieving efficient combustion of solid fuels, especially biomass, with a low negative impact on the environment is rather complicated. Incorrect settings of combustion conditions can cause various problems like increased production of emissions and ineffective using of energy content of burned fuel. Combustion process may be influenced by many factors. This work deals about the impact of various aspects on the production of gaseous emissions, specifically carbon monoxide and oxides of nitrogen, during wood pellet burning in small automatic heat source. During the experiments the impact of amount, temperature and relative humidity of combustion air has been determined. The impact of fuel moisture and fuel supply was also determined. The results showed that all these aspects have a significant impact on the thermal power of heat source and production of carbon monoxide and oxides of nitrogen.
