摘要
the subject of the invention is a method and burner for combustion of coal dust in the energy stream of oxygen of high concentration, intended for applications in the electricity heating, meeting the european union standards for emissions of nitrogen oxides nox and carbon dioxide co2 to the atmosphere.is characterized by the fact that an oxidizer is subdivided into the original oxygen mixed with exhaust recyrkulacyjnymi from boiler, directed horizontally in the fuel nozzle (dp) of a pneumatic coal dust and the secondary oxygen concentration of 98% - 100%.introduced under pressure above 2 kpa tubing (ptw) of regulatory failure (kl) to nozzle holes n aerobic (dn) distributed peripherally at equal distances on the ring (p) and (ptw), located in the distance (k) which is preferably 0.8 to 1.2 zewnu0119tr diameter znej (s) from the burner outlet (in)in the form of external tube bends u0142ukowo of curvature defined angle contained between 10 - 30 degrees and beam forming 50u00b0 favourably 0,98 - 1,02 distance (k) of the ring (p) from the outlet (in) of the burner.
