Biomass combustion is a modern method of thermal energy production. Flue gas created during the biomass combustion process is characteristic by containing water steam, light airborne ash dust and gases such as carbon dioxide, carbon monoxide, sulphur dioxide, nitrogen oxide. Dust contained in flue gas may be of various shape and size and it may occur in various concentrations. Description of the shape and size of nanometric and submicron particles is very difficult as these particles cannot be measured by standard methods. The non-combustible remainder falls directly to an ashpan that is a part of a combustion device in the form of ash. Smaller lighter particles that are carried by gaseous combustion products and still visible to the naked eye sediment along the flue gas duct. Gaseous products contain also particles of 1 nanometer to 100 micrometers in size which flow directly to the atmosphere and affect the environment as well as human health. The paper deals with the size distribution of particles produced during biomass combustion in the hot water boiler Verner of A251.1 type. Within the experimental measuring the size of submicron particles carried off by gaseous combustion products has been analyzed. Laser diffraction was used to determine the size of ash fractions sedimenting along flue gas duct. Measuring was conducted at various operational modes of the boiler and using various fuels with different energy qualities.
