More importance than ever before is attached to reducing harmful gas emissions from industry, both in Poland and worldwide. Rising prices of gas emissions allowances, stricter criteria for suitability for use and the desire to protect the environment are driving the search for new technological solutions and logistics to deliver cost savings and lower emissions. The creation of an appropriate numerical model can translate into real savings as well as having other beneﬁts. This paper presents a numerical analysis of the basic operating parameters of a low-emission swirl burner. The analyzed burner is a typical example of a burner with air staging. The burner was placed in a cylindrical combustion chamber. In the ﬁrst stage, a cold ﬂow analysis without reaction was performed showing the velocity proﬁle, ﬂow vectors and the ﬂow of coal particles. Then calculations were carried out taking into account combustion of coal dust particles in the chamber. The analysis of combustion products, temperatures prevailing in the chamber and the content of nitrogen oxides is presented.
