Coal is one of the important energy sources due to its abundant reserve and the market of coal fired boiler are expected to increase further. However, when using coal, it is essential to reduce environmental burdens such as high CO_2 and NOx generation. We succeeded to decrease NOx generation by 40% with developed state-of-the-art low NOx coal burner based on the new innovative concept. Developed burner also contributes to CO_2 reduction, since boiler efficiency can be improved by operating with low excess air ratio (<10%) and low unburned carbon in fly ash due to enhanced ignition. Furthermore, NOx generation can be reduced in spite of low AA ratio condition, which mitigates corrosion of the boiler furnace wall by H_2S. Accordingly, new burner realizes substantially boiler operation and maintenance cost reduction.
