Coal nozzle assembly comprising two flow channels

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. 1. 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 a curved or buckled flow path , the nozzle tip further comprising 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 greater than 0° and equal to or less than 90°.2. A coal nozzle assembly for a steam generation apparatus comprising an elongated nozzle body and an inner shell having two nozzle tips at one end thereof; the coal nozzle assembly further comprising means being located in the inner shell upstream of said two nozzle tips and splitting the flow from said nozzle body into the two nozzle tips , the directions of the flow paths of the two nozzle tips enclosing an angle (α) greater than 0° and equal to or less than 90°.3. Coal nozzle assembly according to wherein that the nozzle tips are mounted for pivotal movement about an axis being orthogonal with respect to the longitudinal axis of the elongate body or the inner shell.4. Coal nozzle assembly according to wherein at least one of the nozzle body or the inner shell and the nozzle tips partially overlap.5. Coal nozzle assembly according to in wherein the assembly further comprises an air housing.6. Coal nozzle ...
