燃料

After the research of the past decade and more, it was found that alcohols, ethers and esters are of the potential clean alternative fuels.

随着全球石油资源的不断减少，寻找新的石油替代燃料，特别是清洁燃料，成了各个国家当前迫切需要解决的重大问题。

About 40 calories of fossil fuel energy go into every calorie of feed lot beef in the U.S.

在美国，每耗费40卡路里的矿物燃料能源才能饲养产生一卡路里能量的牛肉（具体数据、调查见参考文献2）相比之下，每耗费2.2卡路里的矿物燃料能源可以生产一卡路里能量的植物性食物（具体数据、调查见参考文献3

About 40 calories of fossil fuel energy go into every calorie of feed lot beef in the US(2) Compare this to the 2.2 calories of fossil fuel energy needed to produce one calorie of plant-based protein.

3约40卡路里的矿物燃料能源进入每个热量饲料很多牛肉在美国（ 2 ）比较，这2.2卡路里的化石燃料的能源需要，生产一卡路里的植物为基础的蛋白。

Fuel vapors can escape from the carburetor float bowl through external vents, internal vents and fuel passages and air bleeds.

燃料蒸汽可以从化油器浮子室通过外部通风口，内部通风口，燃料通道和空气泄放口逸散出去。

Through the flue gas and air characteristic analysis in supercharged boiler,the results showed that the value of parameters would increase with the increase of fuel consumption.And volume heat load of the furnace, fuel consumption, heat change between flue gas and convective heating surface and evaporation value would increase with the increase of compression ratio.The heat calculation would be different because of dissimilar thermal calculation in the turbo-compressor when the boiler load was changed.As the boiler load increased,heat loss in the turbo-compressor would increase and the efficiency of the boiler would decrease.The results of the boiler start-up simulation showed that the time of start-up would decrease with the increase of flue consumption ,but instantaneous pressure amplitude would increase.Steam water"s dymamic diversification would be more complex than flue gas"s,and dynamic characters of their parameters would be changed due to different boiler load and disturbance variable,which was shown by results of the simulation when boiler load was changed.

通过分析增压锅炉内的空气、烟气参数特性，发现随着锅炉负荷的增加，空气和烟气的各项参数值都相应的增加；炉膛容积热负荷、锅炉的燃料负荷随着增压比的提高成比例增加；随着增压比的增大，烟气与对流受热面的换热增加，蒸发量随之增加；由于涡轮增压机组在不同负荷下的热力计算不同而造成增压锅炉在不同负荷下的热平衡计算的不同；锅炉增压机组的总的热损失随着锅炉负荷的增加而增加，而增压锅炉的热效率随着锅炉负荷的增加而减少；锅炉启动模拟仿真结果中发现，锅炉启动时燃料量增加，锅炉的启动时间就会减少，但是瞬时升压速度会增加；而动态负荷变化模拟仿真结果中发现，锅炉汽水侧的变化相比烟气侧更为复杂，且在不同负荷和不同扰动量下，烟气侧和汽水侧的重要参数动态特性是不同的。

Coal, natural gas, and oil are fossil fuels—fuels formed from decaying prehistoric plants and animals.

煤、天然气和石油都是化工燃料——这些燃料是由古代动植物腐烂而成。

In Kenya,eighty percent of pepole depends on fossil fuel for lighting needs .Fossil fuel are oil,natural gas and coal.

在肯尼亚，80%的人用化石燃料照明，化石燃料有石油，天然气和煤。

Anticipating criticism from environmental campaigners, he said he wanted to move the American economy away from fossil fuels and foreign oil towards home-grown fuels and clean energy.

预料到会受到环境保护者的批评，他表示，希望将美国经济对石化燃料和外国石油的依赖转移到国内生产的燃料和清洁能源方面。
