The aim of the paper is a comparative study of co-firing high shares of wooden and agro-biomass with hard coal under oxy-fuel and air conditions in the laboratory scale reactor for pulverised fuels. The investigations of co-combustion behaviour NOx and SO2 emission and burnout were carried out for selected blends. Detailed investigations were concentrated on determining the effect of dosing oxygen method into the burner on NOx emission. The paper presents the results of co-firing blends with 20 and 50% share of biomass by mass in air and oxy-combustion condition. Biomass oxy-cofiring integrated with CCS (CO2 capture) technology could be a carbon negative technology. The reduction of NOx emissions in the conditions of oxy-co-firing is dependent on the concentration of oxygen in the primary stream of oxidiser. A significant reduction of NOx was achieved in the case of low oxygen concentration in the primary stream for each investigated blends. Co-firing of biomass with coal in an oxygen enriched atmosphere enhances combustion behaviour, lowers fuel burnout and as a result increases of the boiler efficiency.
