as shown in fig. 1, the wall-hanging stove according to the present embodiment includes a burner 50; a wall-hanging stove body 10 provided with a flue 11 through which flue gas generated by the burner 50 passes; the heat exchanger 20 is arranged in the flue 11 and exchanges heat with the flue gas passing through the flue 11; and the pore plate member 30 is used as an airflow adjusting device, the pore plate member 30 is installed on the flue 11 of the wall-hanging furnace main body 10, the pore plate member 30 is provided with a plurality of air vents 31 through which the flue gas airflow can pass, and the flue gas airflow flowing through the heat exchanger 20 is disturbed, so that the airflow adjusting device reduces the flow speed difference between different flue gas airflows on different areas of the vertical section in the vertical section vertically corresponding to the flue gas airflow. And then combustor 50 in this embodiment is in the course of the work, to the not good problem of heat exchanger 20 heat exchange efficiency in the hanging stove, this embodiment is through setting up air current adjusting device on flue 11, air current adjusting device disturbs the flue gas air current of flowing through heat exchanger 20, and in the perpendicular cross-section that flue gas air current corresponds perpendicularly, reduce the difference of flow between the different flue gas air currents on the different regions of perpendicular cross-section, make the flue gas air current of flowing through heat exchanger 20 more even between the different positions of heat exchanger 20, the condition that partial flue gas velocity of flow is too big and all the other regional flue gas velocities of flow appear when reducing or having avoided heat exchanger 20 during the hanging stove work, and then the heat exchange efficiency of heat exchanger 20 in the hanging stove has been.
