An oxygen-blown pulverized coal burner for utilization of various kinds of coal was newly proposed and developed. The combustion efficiency of 99.7% was achieved by the moderate swirl burner. The flame stabilization could not be realized by the strong swirl burner, and the content of unburned carbon in ash was more than that of the moderate ...
an enhanced combustion low NOx pulverized coal burner. Two coal nozzle tips were selected for testing as a baseline of current ALSTOM firing system technology, a standard shear bar / air deflector tip and an LNCFS™ P2 tip, ALSTOM's current low NOx coal nozzle tip. Four new coal nozzle tip ideas were selected for evaluation in the first
The effect of OFA ratio on NOx is that it reduces the amount of oxygen in the main combustion zone and makes the pulverized coal burn in stages in the main combustion zone and the burning-out zone. The air staged combustion can effectively reduce the NOx formation during coal combustion. In this section, under the boiler load of …
