Abstract
A coal nozzle assembly for a steam generation apparatus comprising an elongated nozzle body having a nozzle tip at one end thereof; said nozzle tip comprising two channels, each channel having curved or buckled flow paths, the nozzle tip further comprising parting means separating the channels from each other, wherein the directions of the flow paths of the channels at their ends distal from the nozzle body enclose an angle between 0° and 90°. This promotes intersecting and shearing the two partial streams outside the nozzle assembly resulting in a better combustion with reduced NOx-emissions.
