he aim of the experiments is determination of emission concentrations in the observed substances produced in exhaust gas during combustion of various mixtures of waste biomass compacted samples. The samples were pressed into the form of briquettes with a diameter of 65 mm. During the actual measurements the following parameters were monitored: emissions of carbon dioxide (CO2), carbon monoxide (CO), nitrogen oxides (NOx) and flue gas temperature depending on the excess air coefficient. Measurements of emission parameters were carried out in storage heater fireplace with nominal heat output of 8 kW. During the measurements high concentrations of carbon monoxide in excess of the value of 5,000 mg/m3 were determined, especially in the samples of waste from corn cleaning and wheat straw. The results show an excess air factor optimum adjustment on value 3, where the combustion device achieves optimum parameters of CO and NOx emissions. The results of emission measurements confirmed that the excess air is a very important operating variable which affects both monitored emissions concentrations and the combustion temperature in the fireplace.
