The invention discloses a flue gas waste heat recovery steam heat exchanger, and relates to the technical field of flue gas waste heat recovery. The flue gas waste heat recovery steam heat exchanger comprises a base plate. The top of the base plate is fixedly installed at the bottom of a lower steam drum pipe seat. A lower steam drum pipe seat shell is fixedly connected to the outer side of the lower steam drum pipe seat. The bottom of a side collecting box is fixedly installed on the two sides of the top of the base plate. One ends of a plurality of fixing pieces are fixedly connected to oneside of the side collecting box, and the other ends of the fixing pieces are fixedly connected with one side of the lower steam drum pipe seat. The outer side of the lower steaming drum pipe seat is fixedly connected with one end of a first descending pipe. According to the flue gas waste heat recovery steam heat exchanger, temperature circulation between the lower steam drum pipe seat and upper steam drum pipe seat and t
