In the paper a novel construction of a low-pressure drop air-nozzle has been presented. It was designed in order to substitute the arrowhead nozzle working until now with a 535MWe CFB boiler. In comparison to the arrowhead nozzle the new construction has a lower pressure-drop and geometry, which is an effective barrier for backflow of a solid. In the paper numerical simulations as well as experimental studies of a new air nozzle have been presented. Laboratory tests have been conducted on a 3D test-stand equipped with six full scale air nozzles.
