  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。www.170444c.com,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。

  基于煤粉燃烧高效与低污染的综合考虑,提出了“电晕荷电煤粉的强化燃烧机理与实验研究”。即通过高压静电场对固体颗粒和气体能产生荷电作用,一方面气体原子或离子移动动能很高,与煤粉颗粒接触时,可以把部分能量转移到煤粒表面上,导致颗粒处于不稳定的高能状态,增加颗粒表面活性;另一方面电晕使氧气、一氧化碳、甲烷等气体离子、电子化,具有较高的能量,使加快煤粒燃烧反应速度,降低燃烧反应温度成为可能。然而在实际生产燃煤过程中,煤粉通常是处于流动状态。从理论上分析,流动中的煤粉的燃烧效率是大于静态下的煤粉,因此对于煤粉流在荷电下的燃烧强化是有可能的。

  本文在煤粉颗粒荷电成功的基础上,通过利用原有电旋风荷电系统,搭建煤粉流喷射荷电燃烧系统,利用摄影记录分析其着火与燃烧状态,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。

  In this paper, pulverized coal particles are charged on the basis of success, through the use of the original cyclone electrostatic charge system, build the pulverized coal flow injection charge combustion system, using a photographic record and analysis of its ignition and combustion state, using sampling thermal analysis method of burnout, which explore the charged pulverized coal flow combustion status.

  Key words: corona discharge, the pulverized coal flow, combustion, thermal analysis

  China is the worlds largest coal producer and consumer countries, is also one of the world on one of the few countries with coal as the main primary energy, the proportion of coal in Chinas energy consumption structure has been very high. Among them, the majority of coal combustion for power generation and heating industry. For large-scale coal-fired power plants and boilers, pulverized coal combustion is the main combustion. However, the use of pulverized coal combustion efficiency is not high and the environmental pollution caused by burning has been one of the most important factor restricting Chinas sustainable development.Based on comprehensive consideration of the pulverized coal combustion efficiency and low pollution, proposed the strengthening of the corona load coal powder combustion mechanism and experimental study. By high voltage electrostatic field to produce solid particles and gas charged role, on the one hand, the high mobile kinetic energy of the gas atoms or ions, contact with the coal particles, part of the energy transfer to the coal surface, causing the particles in an unstable high-energy state, increasing the particle surface activity; corona the other hand, oxygen, carbon monoxide, methane and other gases, ions, electrons of high energy, to speed up coal particle combustion reaction speed, reduce the temperature of the combustion reaction as possible. However, in actual production during coal combustion, coal is usually in the flow state. In theory, the flow of pulverized coal combustion efficiency is greater than the static pulverized coal, pulverized coal flow in the charged combustion enhancement is possible.On the basis of the coal particles charged through the use of the original electric whirlwind charged system, build a pulverized coal flow injection charge combustion system, the use of photographic records to analyze the ignition and combustion state, the use of sample thermal analysis method to analyze the fuel do, which explore the coal-bearing powder flow combustion conditions.
