As shown in fig. 2, a ventilation baffle 1, which is mounted on a burner, comprises: the wind-proof structure comprises a flat plate body 1-1, and a strip wind-proof area 1-2 and a ventilation area 1-3 which are formed on the flat plate body 1-1, wherein the wind-proof area 1-2 penetrates through two ends of the flat plate body 1-1, the ventilation area 1-3 is positioned on two sides of the wind-proof area 1-2, and a plurality of ventilation holes 1-4 are formed in the ventilation area 1-3.

In this embodiment, the ventilation holes 1-4 are preferably arranged on the flat plate body 1-1 in an array. The aperture sizes of the two adjacent air permeable holes 1-4 in each row are different, and the aperture sizes of the two adjacent air permeable holes 1-4 in each row are different. Therefore, the flowing direction of the secondary air can be disturbed and locally changed, the fire transfer performance is improved, and the resonance noise can be effectively avoided. In other embodiments, the size of each ventilation hole is the same, the ventilation holes are uniformly distributed, or the ventilation holes are randomly distributed on the plate body 1, which is not limited to the embodiment.

The ventilation baffle provided by the embodiment is provided with a wind shielding area and a ventilation area, and when the ventilation baffle is arranged on the combustor, the direct impact of secondary air on the combustion gas flow of the combustor is blocked by the wind shielding area, so that the combustion performance of the combustor can be effectively improved.

Example two

As shown in fig. 3 and 4, a wall-hanging stove comprises a wall-hanging stove body, a burner 2 mounted on the wall-hanging stove body, and an ignition needle mounted corresponding to the burner 2; each fire row sheet of the burner 2 is provided with a fire transfer hole 3, and the fire transfer holes 3 are connected into a line and are indicated by a dotted line A; the burner is characterized in that a first ventilating baffle 4 is installed at the bottom of the burner 2, the structure of the first ventilating baffle 4 is as described in the first embodiment, and a wind shielding area of the first ventilating baffle 4 is located right below the fire transfer hole 3.

In this embodiment, it is preferable that second ventilative baffle 5 is equipped with in the both sides of combustor 2, second ventilative baffle 5, the structure of second ventilative baffle 5 is unanimous with the structure of first baffle 4, the regional right fire transfer hole 3 that keeps out the wind of second ventilative baffle 5, the bottom in the regional wind that keeps out wind of second ventilative baffle 5 with the regional tip of keeping out the wind of first ventilative baffle 4 links together, the ignition needle is located each the space that the regional enclosure that keeps out the wind becomes, can improve the gas concentration around the ignition needle like this, can ignite the gas fast, and it is effectual to ignite. As an alternative to this embodiment, the second ventilation flap is omitted and is not limited to this embodiment.

Referring to fig. 5 and 6, when the conventional wall-hanging stove is burning, the fan is operated, and the direction of the gas flowing in the cavity is as indicated by the arrow in fig. 5. The air between the fire fins flows almost vertically upward since the air upward between each fire fin of the burner is not significantly impeded. For a single fire row piece ignited by the pulse igniter, the air moving upwards can influence the transverse diffusion of the gas ejected from the fire hole of the fire row piece, so that the transverse fire transfer range of the flame at the fire hole of the burner is reduced; meanwhile, for the adjacent fire row sheets, as the fuel gas transversely sprayed from the fire transfer holes is easily mixed and diluted by upward air and then taken away, the concentration at the position is reduced and the residence time is reduced; leading to difficulties in transmitting the fire. And the wall-hanging stove that this embodiment provided, through set up ventilative baffle in the combustor bottom, utilize ventilative baffle to change secondary air's flow direction, avoid the secondary air to strike perpendicularly and propagate the gas that the fire hole erupted, effectively improve combustor and pass horizontal spread fire scope of fire hole department and dwell time, it is effectual to propagate fire, under cold state limit operating mode, also can normally propagate fire work.
