The application discloses flue gas waste heat recovery utilizes system, including flue, draught fan, electrostatic precipitator, heat exchanger, steam engine and the generator that connects gradually, during electrostatic precipitator is taken out the high temperature flue gas from the flue to the draught fan, the process flue gas after electrostatic precipitator removes dust lets in the heat exchanger, carries out heat exchange in the heat exchanger, produces high temperature water vapor, drives the generator electricity generation through the high -temperature steam machine. The basis is novel can to convert the heat in the flue to the electric power energy, can fully retrieve flue gas waste heat, environmental protection and energy saving. 本申请公开了种烟道气余热回收利用系统，包括依次连接的烟道、引风机、静电除尘器、换热器、蒸汽机和发电机，所述引风机将高温烟气从烟道中抽到静电除尘器中,经过所述静电除尘器除尘后的烟气通入换热器,在换热器中进行热量交换,产生高温水蒸气,通过高温蒸汽机带动发电机发电。本新型可以将烟道中的热量转换成电力能源，可以充分回收烟气余热，环保节能。
