1·According to the practice in treating spontaneous combustion coal gangue, we have found the feasible measure, and gained evidence environmental and economic benefit.
通过治理自燃矸石山的实践,找出针对性的切合实际的可行措施,取得了明显的环境效益和经济效益。
2·For example, a steam engine can use coal, newspaper or wood for the fuel, while an internal combustion engine needs pure, high-quality liquid or gaseous fuel.
例如,蒸汽发动机可以用煤,报纸或木头作为燃料,而内燃机需要用纯的,高质量液体燃料或气体燃料。
3·A major disadvantage of coal combustion-and characteristic of industrial cities-has been air pollution by soot, dust, ash, exhaust and large amounts of the greenhouse gas carbon dioxide.
煤炭燃烧的主要缺点——也是工业城市的特色——是烟尘、粉尘、灰渣和废气以及大量的温室气体二氧化碳污染了空气。
4·Nitrous oxide (N2O) is a pollutant gas which has very strong destruction influence on atmosphere environment. Coal combustion in fluidized beds is an important resource for N2O.
氧化亚氮(N2O)是一种对大气环境有很大破坏作用的污染气体,煤的流化床燃烧是其重要来源。
5·Coal is an important energy in China, coal combustion is the primary source of pollutions which cause great destructions to the ecological environment.
煤在我国是一种重要的能源,煤的燃烧是造成我国生态环境破坏的最大污染源。
6·In traditional ways, the optimal air coal ratio is obtained by solving combustion function and finding out the extremum, which is time consuming and unreliable.
传统风煤比寻优通常采用求解燃烧函数解析式,再求极值得出最佳风煤比,这一方法可靠性差而且工作量大。
7·Fluidized bed combustion: a method of burning particulate fuel such as coal in which the amount of air required for combustion far exceeds that found in conventional burners.
流化床燃烧,沸腾床燃烧:一种燃烧颗粒燃料(如煤炭)的方法。燃烧时的空气需求量远远超过常规燃烧器。
8·Researchers in California, Oregon and Washington noticed specks of sulfur compounds, carbon and other byproducts of coal combustion coating the silvery surfaces of their mountaintop detectors.
研究人员在加里福尼亚、俄勒冈、华盛顿发现硫化物、碳及其他燃烧副产品在其山顶的银色探测器上留下了斑点。
9·The combustion and heat transfer in CFB boiler are related with the bed material, while the bed material is formed during the coal combustion, fragment and attrition processes.
循环流化床锅炉炉内的燃烧及传热与炉内床料的状态密切相关,而炉内床料主要是由燃煤含有的矿物组分经过燃烧、爆裂和磨耗过程形成的。
10·The numerical modeling of pulverized coal combustion in an oxygen coal combustor was made by using the continuum trajectory model.
