The Formation of Particulate Matter During the Combustion of Different Fuels and Air Temperatures

Particulate matter (PM) belongs to significant pollutants threatening human health. Therefore, it is important to pay attention on these solid emissions. Several factors, such as type of fuel, quantity and temperature of the combustion air, operation conditions and design of heat source etc., influence on their formation. The aim of this work is investigation of fuel type and various inlet air temperatures on PM formation. The above mentioned parameters were measured in wood stove. In the first stage of the research, there were measured following fuels: beech, spruce wood, birch with bark and birch without bark. The results show that higher PM concentrations were measured during the combustion of birch with bark. The outcome of these analyses is the negative effect of bark on PM formation. In the second stage, there was investigated the effect of different combustion air temperatures on PM formation. Based on the measured results, it can be concluded, that temperature of combustion air has not influence on PM concentration, but it has influence on heat power.
