Effect of Flue-gas Cleaning Devices on Mercury Emission From Coal-fired Boiler

为研究燃煤锅炉烟气净化设施对汞排放特性的影响,采用Ontario-Hydro方法,对设有催化脱硝、静电除尘、海水脱硫的300MW燃煤锅炉排放烟气中汞的含量与形态进行分析,同时测定锅炉的煤、底渣、飞灰等固体样品以及脱硫塔前后、曝气之后海水样品中的汞含量。实验结果为:烟气中的气态汞占总汞的79.1%以上,脱硝催化剂对汞的价态具有强烈的转化作用,烟气中83.4%的气态Hg0被氧化成气态Hg2+;静电除尘对颗粒态汞的去除率几乎达到100%;在脱硫塔中,海水对烟气中汞的洗脱率高达73.6%,曝气后排放前的海水中含汞量是新鲜海水的5.5倍。研究表明锅炉烟气净化设施对汞的排放特性有着重要的影响。In order to study the effect of flue-gas cleaning devices on mercury emission from coal-fired boiler, Ontario-Hydro method had been applied to determine the mercury concentration and speciation in the flue-gas emitted from a 300MW coal-fired boiler, which was equipped with various pollution control devices, including selective catalyst reduction (SCR) De-NOx system, electrostatic precipitator (ESP), and flue-gas seawater De-SO2 system (FGD). Mercury concentration in raw coal, bottom ash and fly ash of the boiler, seawater at the inlet and outlet of SO2 absorption reactor and the drainage of aeration sink, were also analyzed. The results indicate that the percentage of gaseous mercury in total mercury discharged is more than 79.1%. De-NOx catalyst strongly affects the mercury speciation transformation, showing a conversion rate of 83.4% for Hg0 to Hg2+. The removal efficiency of particulate mercury by ESP is close to 100%. With seawater FGD, the removal efficiency of mercury is as high as 73.6%. The mercury concentration in the seawater of drainage from aeration sink is 5.5 times higher than that in fresh seawater. The study shows that the flue-gas cleaning devices in coal-fired power plant play an important role on mercury emission characterization

名牌意识与名牌出路

企业呼唤名牌意识何谓名牌？何谓名牌意识？名牌是凝结在产品中的出色劳动,是高质量的标志。它由产品名称、辞句、图案、色彩、标志和设计等多种组合而成,也是企业信誉的体现。名牌意识就是对名牌产品的观念看法和重视程度。改革开放以来,商品的进出口政策放宽,一些外商看准中国是一个潜方巨大的市场,不惜重金打开并占领中国市场,洋产品长驱直入。如今,象美国万宝路、法国人头马、日本松下

中国与周边国家国际旅游发展特征及其对比

基于地缘因素,根据国际旅游组织提供的权威资料,以中国为中心参照物,将中国与日本、韩国等18个邻国作为一个统一的旅游大市场,定量对比分析了19个国家国际旅游发展的基本特征。基于国家战略利益思考,揭示了中国在发展入境旅游方面所面临的机遇和挑战:中国入境旅游人数在19国中位居第一,年均所在国旅游花费在19国中位居第二,出境旅游人数位居第三,三者在总体上随时间均呈现出递增趋势,中国在各国中增长幅度最大;每平方公里国土面积上中国年均入境旅游人数、年均入境旅游花费远低于日本、韩国与泰国;中国入境旅游花费占GDP份额在各国中位居第八,总体上呈现出递减趋势;中国出境旅游人数位居第三,在他国旅游花费位居第二。进而指出日本、韩国、泰国已成为中国发展与开拓亚太(东盟、澜沧江-湄公河次区域)入境旅游市场所面临的三大主要竞争对手。最后,还探讨性地提出了当前以"惠邻"、"睦邻"、"安邻"为核心的我国参与周边区域国际旅游合作的国家战略选择模式,认为我国应将发展国际旅游作为与周边国家(区域)合作的重要桥梁与优先纽带,从国家战略利益的高度予以积极重视
