应用灰污热流计监测燃煤锅炉炉膛灰污结渣的动态过程 总被引:4,自引:0,他引:4
针对煤粉中混入造纸黑液后易结渣高碱燃料的结渣特性,将自制的水冷灰污热流计应用于工业性试验中,结合电子探针进行分析。提出灰渣沉积的3层沉积层———初始沉积层、一次沉积层和二次沉积层,并从宏观角度、微观结构、微区成分3方面给予论证。这有助于锅炉沾污结渣机理的研究。此外,通过数据采集仪,获取灰污热流计探头上温度信号,可以掌握热流密度随沾污结渣的动态变化,能够有效地监测炉内沾污结渣的发展,优化吹灰,在工程应用和试验分析中具有一定作用。图7表3参8 相似文献

The assessment of the influence of fouling and slagging on the heat transfer in utility boilers has obtained significant interest both during boiler design and operation. This paper presents a strategy to investigate this influence by introducing heat resistance to represent fouling and slagging on furnace walls. The evaluation of this strategy was performed using the plant heat flux reading data together with a 3‐D computational fluid dynamics code. The model considers the influence of the operating conditions to the incident heat fluxes and these are used to assess the heat transfer resistance from the measured absorbed heat fluxes.

脱硫是使用中小型锅炉的企业所必须面对的一个关键课题,降低燃煤锅炉燃料燃烧所产生的SO2排放量的方法有很多,本文在对型煤进行有机钙脱硫实验的基础上,证明了以有机钙代替传统的石灰石、大理石粉作为固硫剂,既能达到较高的脱硫率,又对工业废物进行了二次利用,因此,推广应用价值较高。 相似文献

Fouling on boiler beating surfaces is one of the important factors that damage boiler‘s economical performance and safety,with on-line monitoring of foiling states on boler heating surfaces,it is possible to optimize sootblower system,to visualize fouling states,to improve performance,as well as to remedy the insufficiency of experiment research in boiler heating surface fouling process.New method based on Fuzzy Neural Network(FNN) is presented to monitor fouling states on boiler heating surfaces on-line.Compared with regular methods,since FNN‘s reasoning process is transparent and comprehensible,it is possible to explain and comprehend reasoning process,which makes the FNN based system perform as an additional operation consulting system. 相似文献
