从目前立式燃油锅炉的发展现状出发,针对某小型立式燃油锅炉热效率不高,NO_x排放偏高的缺点,提出了相应改造方案,建立传热模型分析改造前后炉内燃烧与传热过程,并通过实验进行相关测试研究。经过分析和实验,结果表明:通过在炉膛中加装内炉胆,强化了燃烧与传热过程,提高了热效率,并改善了烟气排放;改造后的燃油锅炉炉膛温度分布均匀,无明显高温区,过量空气系数由1.10降低至1.05以下,NO_x排放降低25%以上,排烟温度明显降低,热效率提高2个百分点左右,以上均证明了该改造方案的可行性。 相似文献

This paper reports the development effort of using coconut shell-based fuel slurries in an oil-fired foundry furnace. Solid fuel fines were dispersed in a liquid medium and the resultant fuel slurry was burnt like a liquid fuel. Light disel oil, furnace oil and water served as the liquid media. The solid fuels burnt were pulverized coal and pulverized coconut shell. The solid fuel was directly mixed with the liquid medium and was burnt in an oil-fired foundry furnace. No chemicals were used for the stabilization of slurries. Pulverized coal was found to settle down and was often blocking the fuel atomizer. But no such problems were encountered when pulverized coconut shell - light diesel oil and pulverized coconut shell-water slurries were burnt. Among the various slurries burnt, the pulverized coconut shell-water slurry was found to be the most appropriate slurry to be used in the oil-fired foundry furnace without any modifications to the existing furnace hardware. Preliminary results are presented. 相似文献
