This paper describes the numerical investigations of the influence of the blending method on the combustion characteristics and NOx emission in a 500 MW, tangentially coalfired boiler. The infurnace and outfurnace blending methods are simulated with the blend of 60% bituminous and 40% subbituminous coals on a weight basis. The simulation shows the blending method has a great effect on ...
