The utility model provides a radiation burner, wherein a combustion plate 3 is arranged in a cavity 2, so that fuel gas is combusted in the cavity 2, heat energy generated by combustion is transmitted to a radiation plate 5 through radiation and convection, the radiation plate 5 can be a light thin plate, no pore is formed on the surface, impurities or other impurities in air cannot block the radiation plate 5, and the radiation plate 5 is convenient to clean.

The air inlets 21 are circumferentially spaced at the bottom of the chamber 2. It is ensured that a mixture of gas and air can enter the chamber 2 through the inlet 21. The shape of the air inlet 21 may be circular, square, triangular or other irregular shapes. In the present embodiment, the air inlet 21 is circular, and smooth transition is adopted, so that noise can be reduced. Preferably, a flow guide structure is arranged at the air inlet 21 and used for guiding mixed gas of fuel gas and air when entering the cavity 2, so that noise can be reduced.
