Life cycle emissions of greenhouse gas for ammonia scrubbing technology

It is thought that the CO₂ emissions from coal-fired power plants contribute greatly to the total anthropogenic CO₂ emissions. Ammonia solvent can be used to absorb the CO₂, called ammonia scrubbing. However, as has been pointed out, the production of ammonia would emit CO₂; therefore, the effectiveness of ammonia scrubbing is doubted. The paper focuses on the problem. Two systems are defined in the paper. System I is CO₂ absorption by ammonia scrubbing, and system II is industrial production of ammonium bicarbonate. The total CO₂ emissions of the two systems are calculated by means of life cycle assessment. The paper shows that the total CO₂ emissions of ammonia scrubbing are less than that of the industrial production of fertilizer ammonium bicarbonate. It can be concluded that ammonia scrubbing is an effective way to reduce the anthropogenic CO₂ emissions. This work was presented at the 6 ^th Korea-China Workshop on Clean Energy Technology held at Busan, Korea, July 4–7, 2006.

回转窑托轮的调整(二)

2 回转窑筒体轴向窜动的控制 由前所述,回转窑筒体因倾斜放置,在运转时发生沿轴向下窜是必然的。如果不加控制就会发生掉窑或窑体下炕的重大设备事故。这种事故确实在一些水泥厂中发生过,如抚顺水泥厂。但是,如果采取一定的措施,使回转窑筒体在运转时不发生窜动是完全可能的。可是这样做会导致托轮和轮带表面的磨损不均,表面母线出现凹凸现象,大小齿轮两侧很快出现台棱,有时由此会引发不应有的事故。因此必须对窑体的窜动进行控制。     

The influence of high-temperature crystallite growth and petrography of pulverized char on combustion characteristics

In this paper, Yangquan anthracite was separated into three different coal lithotypes in terms of density. The effect of high-temperature crystallite growth on char combustion of coal is characterized. It shows that there is large difference between the combustion characteristics of the two lithotypes of coal (one is <1.55 g/ml of density and the other is 1.55-1.855 g/ml), and that the development of structural ordering decrease the combustion rate to a certain degree. The precise method of using thermogravimetry analyser to study the kinetics of char combustion reaction is also discussed. Besides, a feasible measure to process the experimental data is introduced.     

回转窑煤粉燃烧器推力的分析和计算

燃烧器将煤粉喷射到窑内燃烧,只有火焰形状合理,才能满足窑内的温度分布符合物料在各段进行反应所需要的温度。要获得合理的火焰形状,就必须有足够的能量支撑。目前,国内外对这种能量的表示方法基本上有三种:一是能量表示法或称动能表示法,二是单位热量推力表示法,三是相对推力表示法,以最后一种最直观,最简便。煤粉燃烧器的推力,不管用什么方法表达,只是具体数值不同,而其实质是相同的。燃烧器的推力不宜过大,关键在够用。
