Abstract

The invention provides a combustor for heating inside a container, which is capable of improving durability of the component in proximity of the combustion surface by preventing backfire. The combustor for heating inside container is connected with gas supply means, and mounted onto a ladle. The combustor for heating inside the container comprises a gas passing portion, a gas spraying portion, a metal weaving portion and a connection portion. The gas passing portion is used for passing the gas supplied by the gas supply means. The gas spraying portion is connected with the gas passing portion,and is constructed into a hollow structure according to different construction. The metal weaving portion is in contact with the surface of the gas spraying portion. The connection portion is connected to the ladle, and causes the gas spraying portion and the metal weaving portion in opposite with the inner surface of the ladle. The gas spraying portion comprises a plurality of spraying pores. The plurality of spraying pores are covered by the metal weaving portion. And the diameter of the spraying pore is below the thickness of the gas spraying portion.

Description

technical field [0001] The present invention relates to a burner for heating inside a container, and more particularly, to a burner for heating inside a container capable of improving the durability of members near a combustion surface by preventing flashback. Background technique [0002] Patent Document 1 discloses a surface combustion type burner. The surface-fired burner includes a combustion surface and a premixed gas chamber behind the combustion surface, and the premixed gas chamber is connected with a premixed gas supply pipe. In addition, the premixed gas is introduced into the premixed gas chamber from the premixed gas supply pipe, burns on the surface of the combustion surface, and uses the heat of the high-temperature combustion exhaust gas generated thereby and the radiant heat from the surface of the combustion surface to heat the molten metal in the chamber. The molten metal is heated and maintained at a specified temperature. [0003] According to the techn...
