The present invention proposes a ceramic burner (20) for use in a combustion chamber (12) of a regenerative heat generator, such as a hot blast stove (10) of a blast furnace. The ceramic burner (20) comprises a burner feed chamber (21) with a partition wall (30) for dividing the burner feed chamber (21) into a fuel chamber (24) and an air chamber (28). The fuel chamber (24) has a fuel inlet (22) for receiving combustible fuel and a fuel outlet (32) for feeding the combustible fuel to a mixing zone (34). The air chamber (28) has an air inlet (26) for receiving combustion air and an air outlet (36) for feeding the combustion air to the mixing zone (34). According to an important aspect of the invention, the ceramic burner (20) further comprises a gastight metallic fuel container (48) arranged in the burner feed chamber (21), the fuel container (48) comprising the fuel chamber (24) therein, a wall portion of the fuel container (48) forming the partition wall (30) between the fuel chamber (24) and the air chamber (28).
