Zusammenfassung:	The invention relates to a coke oven flue-gas waste-heat and dry-quenching waste-heat coupled power generation system and a coupled power generation method thereof. The system comprises a dry-quenching waste-heat recycling device and the dry-quenching waste-heat recycling device comprises a dry-quenching furnace and a dry-quenching waste-heat boiler which are communicated with each other. A dry-quenching secondary superheater, a dry-quenching primary superheater, a first evaporator, a second evaporator, a coke oven flue-gas waste-heat superheater and a dry-quenching economizer are sequentially arranged in the dry-quenching waste-heat boiler. A coke oven flue-gas waste-heat recycling device comprises a coke oven. A coke oven flue-gas main channel is connected to the coke oven and sequentially connected with a coke oven flue-gas waste-heat economizer, a coke oven flue-gas waste-heat evaporator, a coke oven flue-gas draught fan and a coke oven flue-gas chimney. A steam turbine generator unit, the dry-quenching waste-heat recycling device and the coke oven flue-gas waste-heat recycling device form a loop through a condensing unit. According to the coke oven flue-gas waste-heat and dry-quenching waste-heat coupled power generation system and the coupled power generation method, coupled power generation is achieved in the manner that coking flue exhaust fume waste heat enters dry-quenching waste-heat power generation circulation in a coupled manner, and the purposes of efficient utilization of secondary energy and energy saving and emission reduction are achieved.
