我国是世界上最大的煤炭生产和消费国,也是世界上为数不多的以煤炭为主要一次能源的国家之一,煤炭在我国能源消费结构中的比例一直很高。其中,大部分煤炭进行燃烧用于发电与供热等产业。对于大型的燃煤发电站和锅炉来说,煤粉燃烧是最主要的燃烧方式。但是,煤粉燃烧的利用效率不高和由燃烧造成的环境污染一直是制约我国可持续发展的最重要的因素之一。
China is the world's largest coal production and consumption in the world, but also few to the coal is the main energy in one of the countries, the coal in structure of consumption of our country energy ratio was very high. Among them, most of the coal combustion for power generation and heating industry. For large coal-fired power station and boiler, pulverized coal combustion is the main way of combustion. However, the use of pulverized coal combustion efficiency is not high and the environmental pollution caused by burning has restricted the sustainable development of our country one of the most important factors.
基于煤粉燃烧高效与低污染的综合考虑,为了对“电晕荷电煤粉流的强化着火与燃烧”理论进行试验验证,进行了荷电煤粉流燃烧试验研究。主要完成了实验系统设计、搭建、试验准备、具体试验及数据处理和总结。采用气动-螺旋微量给粉器进行煤粉供给与输送,利用电旋风荷电器实现煤粉颗粒荷电,连接于可视滴管炉完成煤粉流燃烧,利用高分辨率数码摄影记录其着火与燃烧状态,借助于专用软件进行图像分析,利用取样热分析方法分析其燃尽情况,由此探索荷电煤粉流燃烧状况。
Based on the coal combustion efficiency and low pollution into consideration, in order to" the corona coal powder flow enhanced ignition and combustion theory" test, were charged pulverized coal flow combustion test research. Completed the main experimental system design, build, test preparation, specific test and data processing and summary. Using pneumatic screw micro-feeding powder for coal supply and transportation, the use of electric charge electric appliance of the pulverized coal particles in cyclone charged, connected to the drop tube furnace pulverized coal combustion in a stream of visual completion, using high resolution digital photographic records of the ignition and the combustion state, with the aid of special software for image analysis, using sampling thermal analysis method of burnout situation, the exploration of charged pulverized coal flow combustion status.
本文采用的方法具有创新性,并且从实验结果分析中得出荷电煤粉流与不荷电煤粉流相比,着火提前,燃烧强化,燃尽性更好,试验研究达到预期效果。
This paper uses the method of innovative, and from the results of the experiment analysis shows that the load of coal powder flow with and without load of coal powder flow, ignition, combustion, complete combustion test research better, achieve the desired effect.
觉得可以就给分!谢谢 Feel can give points! Thank you
China, it is most coal producing and consuming country as it is few to take it as main once energy consumed country in the world. coal is in high proportion of our consumption energy structure. further, the most coal is for generating and heat thru burning like state-owned power station and boiler with coal firing as main methodology. however, this method is not highly utilizing the energy but polluting the environment, which is one of factors constrainted our sustainable developed strategy.
this article consideres the balance of coal burning and low pollution and experiment evaluation to the new method by fired and burn the coal thru electron involving experiment design, build, preparation and prototype and study the consequence........connected with visible tubes and stoves, photoed and recorded burning status by high resolution camera, analysized thru professional sw like ansys, solidworks to expored burning status better.
采用气动-螺旋微量给粉器进行煤粉供给与输送,利用电旋风荷电器实现煤粉颗粒荷电,连接于可视滴管炉完成煤粉流燃烧,这句话请给出相关专业术语。文中打点的部分。谢谢!
