For one brown coal type twofold increase of nitrogen content resulted in NO, emissions increase of about 30%. Increasing rank from brown coal to bituminous coal increases NO emissions and next a fall in the anthracites range. With nitrogen content increase NO - emission grows a~d the ratio of fuel nitrogen conversion to nitrogen oxide decreases. Experiments results and their statistical analysis were used to determine relationships describing NO, emissions and conversion ratio of fuel nitrogen to nitrogen oxide as functions of two variables. describing coal properties, i.e. nitrogen content and fuel ratio (fixed carbon to volatile matter ratio).}, type={Article}, title={The Influence of the Type and Quality of Coal on NO, Emission During Pulverised Coal Combustion}, URL={http://www.journals.pan.pl/Content/123494/PDF/4_AE_VOL_30_1_2004_Rybak_The_Influence.pdf}, keywords={nitrogen oxide emission, power engineering, coal combustion}, }
