摘要：

The research carried out on real gases testified to the possibility of intensifying the denitrification of flue gas from coal dust and grate boilers. This was done through the activities aiming at nitrogen oxides removal within the burning zone due to urea injection. The experiments allowed us to establish the influence of powdered urea addition to the coal dust boiler's burning zone on the concentration of nitrogen oxides in flue gases as well as the influence of urea/nitrogen oxide molar ratio on the effectiveness of flue gases denitrification using the mixtures of urea and hydrated lime or calcium carbonate. The influence of urea/nitrogen oxide molar ratio on the quantity of flue gases emitted from grate boiler and the influence of urea solution concentration on the extent of denitrification were also determined.
