摘要:
对现有电站污染物控制装置基础上进行技术改造,协同实现汞污染控制是行之有效的技术方案,汞污染控制系统的技术经济性评估是燃煤电站管理者面临的首要问题.用Integrated Environmental Control Modeling(IECM)软件模拟了温度、煤种及空气污染控制装置的配置对活性炭吸附电站燃煤烟气汞效果的影响,并对不同条件下,活性炭的喷射量进行了模拟和经济性分析.结果表明活性炭捕获汞的效果是与排烟温度成反比的.对于燃烧烟煤的电厂,加入烟气脱硫装置(FGD)后活性炭的喷射量将大大减少,再结合选择性催化还原装置(SCR)后,可以达到很高的汞脱除效果;对于无烟煤和褐煤,加入烟气脱硫装置(FGD)可减少约27%的活性炭喷射量,但再加入催化还原装置(SCR)后,对活性炭的注入量几乎没有影响.
Abstract:
The techno log ica l upg rad ing based on the ex isting po llution contro l dev ices is an e ffective solution tom ercury po llution control in coa l??fired power plants. The most im po rtant issue fac ing m anagers is the techn ica l and econom ic e?? va luation fo rm ercury po llution contro l dev ices. The e ffects of the operating temperature, coa l type and con figuration o f the a ir po llution contro l dev ices on them ercury adsorption by activated carbon in jection for coa l??fired flue gas w ere pre?? d icted in th is pape r. The sim ulation and econom ic analysis on the in jec tion o f activated carbon under diffe rent operation cond itions we re a lso carr ied out w ith the so ftw are o f Integrated Env ironmenta l Contro lM ode ling ( IECM ). The results show that the effect o f activated carbon onm ercury rem oval is in inve rse proportion to the temperatu re of flue gas. For the b itum inous coa l??fired powe r plant, the flue g as desulfur ization ( FGD) sy stem reduces the am ount of the in jection of acti?? va ted carbon significantly. Com bined w ith the selective ca talytic reduc tion( SCR) system, the h igher rem oval e fficiency form ercury in flue gas can be ach ieved; For an thracite and lignite??fired bo ile rs, the activa ted carbon injection cou ld be reduced by about 27% by flue gas desulfur ization ( FGD) system, and there is no obv ious impact of configuration com?? b ined w ith the se lective cata ly tic reduction( SCR) on the injection of ac tivated carbon.
