[0007] The fire cover is special in that: the radial discharge plate is provided with a cavity with a lower opening, and a discharge column is provided on the top plate of the cavity.

[0008] The fire cover is special in that the discharge column is in the shape of an inverted truncated cone.

[0009] The fire cover is special in that: the combustion chamber is in a circular ring shape;

[0010] A truncated cone portion is provided on the upper portion of the outer ring wall plate of the fire cover body, and the combustion hole is provided on the truncated cone portion.

[0011] The fire cover is special in that a flame stabilizing groove and an air guide hole are arranged at the lower part of the fire cover body, and the air guide hole connects the flame stabilizing groove and the combustion chamber.

[0012] The fire cover is special in that the combustion chamber is in the shape of a cylinder with an opening at the bottom.

[0013] A stove burner is special in that it comprises the fire cover as described above.

[0014] The utility model discloses a fire cover. The radial discharge plate is arranged to ensure accurate and reliable ignition. The arc-shaped baffle plate is arranged to prevent the liquid flowing to the top from flowing onto the radial discharge plate and into the combustion hole, thereby preventing the combustion hole from being blocked and improving the ignition speed.
