Experimental investigation on the characteristics of Y-Jet semi-internal and Y-Jet internalCWS atomizers have been carried out carefully. The effects of their configuration, sizes and ope-ration parameters on turndown ratio and atomizing air consumption ratio and on spray features arediscussed. The experimental results show that these two types of atomizer with typical size havelarge turndown ratios and low atomizing air consumption ratios and good spray quality. The Y-Jet Simi-internal CWS atomizer with axial...

The dynamic sulfur emission derived from combustion of lignite blends is studied in a tubular furnace. It is found that the sulfur emission procedure of component lignite in blends is hardly affected by each other. In combustion of component lignites or their blends, two characteristic peaks are formed on the sulfur release rate curve versus experimental time, which are closely related to the sulfur patterns in raw coal and their thermal stabilities. The two sulfur release rate peaks derived from combustion...

The dynamic sulfur emission derived from combustion of lignite blends is studied in a tubular furnace. It is found that the sulfur emission procedure of component lignite in blends is hardly affected by each other. In combustion of component lignites or their blends, two characteristic peaks are formed on the sulfur release rate curve versus experimental time, which are closely related to the sulfur patterns in raw coal and their thermal stabilities. The two sulfur release rate peaks derived from combustion of blends composed of three lignites, such as Gushan lignite, Fengshuigou lignite and Yuanbaoshan lignite, are respectively gentler than those of blends composed of the latter two lignites. With an increase in blend ratio of lowsulfur Fengshuigou lignite, the maximum sulfur release quantity and two sulfur release rate peaks derived from lignite blends combustion all decrease, while the two characteristic peak times are both postponed.

研究了多种褐煤混烧时硫污染物的动态排放特性,发现单煤及混煤燃烧时硫析出速率曲线均呈现出典型的双峰结构.由古山煤、风水沟煤和元宝山煤配成的三元混煤的硫析出速率双峰比后两者配成的二元混煤更趋于平缓.当低硫的风水沟煤掺配比增加时,二元或三元混煤的最大硫析出量均逐渐减少,硫析出速率双峰均逐渐降低,其峰值时间均有所延迟.

The combustion characteristics of various coals (anthracite, lean coal and bituminous coal) and their blends were investigated in a one-dimensional sedimentation furnace. The impact on NO_ x emissions of various factors was analyzed along with a discussion of the effect on burnout rate of different excess air factors, mixing dilution ratios and the ratio of primary and secondary air. Test results indicate that when bituminous coal accounts for 25% of the blended coals the NO_ x emissions are relatively low....

The combustion characteristics of various coals (anthracite, lean coal and bituminous coal) and their blends were investigated in a one-dimensional sedimentation furnace. The impact on NO_ x emissions of various factors was analyzed along with a discussion of the effect on burnout rate of different excess air factors, mixing dilution ratios and the ratio of primary and secondary air. Test results indicate that when bituminous coal accounts for 25% of the blended coals the NO_ x emissions are relatively low. In case of burning blended coals there emerged several NO_ x emission peaks along the axis of the furnace, which are caused by the different characteristics of the coals taking part in the combustion.
