摘要
介绍了气气换热器的作用和工作原理,通过监测洛河电厂大气污染源的排放浓度,模拟预测FGD取消GGH对大气污染物扩散的影响。结果表明:在D类稳定度下FGD系统取消GGH装置的烟气抬升高度比设置GGH时减少110米;在静风条件下,FGD系统取消GGH装置大气污染物的扩散对关心点的影响不甚明显.
The paper introduce the role and principle of the GGH（gas to gas heater）,monitoring of air pollution source＇s concentration,simulation is selected and the effects on atmospheric pollutant dispersion is forecasted after canceling the GGH device from FGD system.The results are as follows：Under D stability conditions,when cancelling the GGH device from FGD system,the lifting height of smoke reduces 110 meter compared with setting the GGH device;Under static wind conditions,mass of concentration of sensitive points changes little between setting and canceling the GGH device from FGD system.
