Brief Discussion on the Existing Questions for Environmental Impact Assessment of Natural Draft Cooling Towers(NDCT)with Flue Gas Inj ection in Coal-fired Power Plants Li Lifeng,Zhang Shushen (Dalian University of Technology,Dalian 1 1 6024,China) Abstract:This study gave a detailed introduction about the present techniques of Natural Draft Cooling Towers(NDCT)with flue gas injection in domestic and overseas coal—fired power plants.The process flow and technology characteristics of the evaluated Natura1 Draft Cooling Towers(NDCT)with flue gas iniection projects were elaborated and analyzed.The environmental impact results of the two flue gas ex— hausting methods in coal—fired power were compared in detail.The existing questions for the environmen— ta1 impact assessment on the NDCT techniques were put forward and discussed briefly.
