请将下面这几段话翻译成英文:
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.
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.

关键词:电晕荷电,煤粉流,燃烧特性,热分析

答案和解析
China is the world's largest coal production and consumption Country,and is also one of the few countries which regard coal as the main sources of energy ,the coal energy rates was very high among energy consumption structure rates in our country.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, It's one of the most important factors which has restricted the sustainable development that the use of pulverized coal combustion efficiency is not high and the environmental pollution caused by burning of our country one of the most important factors.
Based on the coal combustion efficiency and low pollution comprehensive consideration," corona charged pulverized coal combustion mechanism and experiment research" is put forward.By means of high voltage electrostatic field on the solid particles and gas can produce electric charge effect,On one hand, the gas atoms or ions moving kinetic energy is very high,and when contact with the pulverized coal particles,it'll transferred part of energy to the coal particle surface, and lead to Particles in an unstable high-energy state , increased the particle surface activity; On the other hand, oxygen, carbon monoxide, corona methane gas ion, electron, has high energy, those make accelerate coal particle combustion reaction rate, reduce combustion reaction temperature become possible. However, in the actual production process of coal, coal is usually in a flow state. From theoretic analysis, the flow of pulverized coal combustion efficiency of pulverized coal is greater than under the static state, Therefore,the pulverized coal flow in charge of combustion enhancement is possible.
In this paper,on the basis of pulverized coal particles are charged successfully, through using of the original cyclone electrostatic charge system to 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 to exploring Charged pulverized coal flow combustion status.
Key words: corona discharge, the pulverized coal flow, combustion, thermal analysis
