Device for introducing gas into a container having a liquid hot medium, comprises a gas inlet temperature resistant element comprising molybdenum disilicide at an end of the gas inlet element and is arranged at a place of container

The device (1) comprises a gas inlet temperature resistant element (4) comprising molybdenum disilicide at an end of the gas inlet element and is arranged at a place of container (2). The gas inlet element has a predetermined inner diameter, which is dimensioned so that the liquid medium does not penetrate into the opening of the gas introduction element because of its viscosity, for example, iron and steel have the diameter of 2-7 mm. The outer diameter of the gas inlet element is 5-50 mm. The gas inlet element has a material that exhibits ceramic properties and resistance to endogenous.

The outer diameter of the gas inlet element is 5-50 mm. The gas inlet element: has a material that exhibits ceramic properties and resistance to endogenous and/or exogenous e.g. siliconized silicon carbide, where the material is sintered; at temperatures of less than 550[deg] C forms a protective action unfolds at the surface of a quartz glass layer; and is inserted into an adapter in the end. The cross-sectional shape of the gas inlet element is arbitral such as round, and/or oval or square. A bushing that has the inner diameter which is small compared to the length of the gas inlet element. The adapter has a thread on the surface, where the thread is present in contact with water jet assistance at the end of a lower portion (14). The transition portion of geometric dimensions, forms of the end of the gas inlet element and the end of the lower portion of the water jet assistances are adapted. Independent claims are included for: (1) a gas inlet element of a ceramic sintered material; and (2) a method for introducing gases into a hot medium with a gas inlet element.
