The European Union markedly favors the use of renewable energy sources. Biomass is one of the renewable energy sources suitable for the production of heat for heating, especially in the conditions of the Czech Republic. Technologies for combustion of common wood biomass are well handled in practice, and the legislation of domestic boilers is exclusively carried out by the combustion of wood biomass. The problem occurs during the combustion of agro-pellets when gaseous emissions and solid particles concentrations are much higher compared to emissions from wood pellets. In this work, the results of gaseous emissions and solid particles from the combustion of various types of biomass pellets in Verner A251 automatic boiler are presented. Various influences on the production of gaseous emissions, such as different O2 levels, pellet diameter, and composition, are discussed. Siemens Ultramat 22 gas analyzer was used to measure flue gas composition; it continuously recorded the oxygen concentration and the amount of carbon monoxide and nitric oxide. Solid particles were collected using an isokinetic gravimetric method. The results show that with increasing diameter of wood pellets the amount of nitric oxide increases while the amount of carbon monoxide decreases. Wood pellets compared with pellets of hay, rapeseed, wheat, spruce, beech, and a mixture of seeds show the lowest values of carbon monoxide, nitric oxide, and solid particles. The highest values of carbon monoxide, nitric oxide, and solid particles were measured for rapeseed and hay pellets. During the investigation of the effects of different oxygen levels it was found, that with increasing oxygen levels, carbon monoxide emissions dropped while emissions of nitric oxide remained almost constant. The obtained results can be further used in design modifications of burners and combustion chambers and can help in setting the operating conditions.
