摘要:
This paper reports the experimental research on combustion and pollution properties of several typical Chinese individual coals and coal blends and the methods determined optimum blending ratios. Thermogravimetry analysis technique and a drop-tube furnace were used to investigate the ignition and burnout behavior and NOx emission characteristics. Ash chemical composition and fusion temperature was also measured. The effects of the blending ratios on ignition, burnout, slagging and NOx emissions have been analyzed. The fuzzy logic approach has been used to determine the optimum blending ratios based on experimental data which provide a scientific basis for design and operation of power station blending coal. Calculation results were comparable with that of results obtained from combustion test carried out in a boiler simulator furnace.
