Abstract
A coal-water slurry liquid fuel or coal or other liquid fuel is atomized for combustion in the reburn zone of a boiler with a relatively small addition of natural gas to produce NO.sub.x reductions comparable to the reburn effect of natural gas alone as well as a more uniform temperature profile in the upper combustion zone of the boiler.
