Abstract:

Abstract:with the more and more strictly requirements for the discharge of the pollutants,the coal fired plants were carrying out a large scale flue gas ultra clean emission actions.At present,there were three mainly current streamline emission technology schemes.In this paper,the 3 schemes were expounded respectively and their characteristics were analyzed,which provided the references for selection of the technology to the flue gas ultra clean emissions.

Key words: Keywords:wet flue gas desulfurization, ultra clean emission, desulfurization process flow, series connection absorption tower , twin towers double cycle, wet electrical dust precipitator
