Burner arrangement

Abstract

The invention relates to a burner arrangement ( 1 ) in particular for heating, drying or keeping warm, in particular a distributor ( 5 ) of a continuous casting unit and consisting of a flat arrangement of at least one burner ( 2 ). The burner(s) ( 2 ) is/are embodied as a porous burner ( 10 ).

1 . A burner arrangement ( 1 ), especially for heating, drying or keeping hot especially a tundish ( 5 ) of a continuous casting installation, with a flat arrangement of at least one burner ( 2 ), wherein the burner or burners ( 2 ) are realized as porous burners ( 10 ), wherein the porous burner ( 10 ) has porous burner segments ( 11 ,  12 ,  13 ), and the porous burner segments ( 11 ,  12 ,  13 ) are supplied with fuel and/or an oxygen carrier by supply lines ( 4 ), and at least some individual supply lines ( 4 ,  14 ,  15 ) are supplied with fuel and/or an oxygen carrier by a common supply line, and, in addition, a blower ( 6 ) is provided for supplying the oxygen carrier through the supply lines, and wherein the porous burner arrangement ( 10 ) is held by a swivel arm ( 3 ), which has a joint that allows it to swivel, and the blower ( 6 ) is likewise held by the swivel arm ( 3 ), so that the blower ( 6 ) can also be swiveled. 
   
   
       2 . A burner arrangement in accordance with  claim 1 , wherein the porous burner segments ( 11 ,  12 ,  13 ) of the porous burner ( 10 ) are arranged flat in a row or rows. 
   
   
       3 . A method for controlling a burner arrangement in accordance with  claim 1 , wherein porous burner segments ( 11 ,  12 ,  13 ) are turned on and/or off as a function of the desired heating intensity or heating power. 
   
   
       4 . A method for controlling a burner arrangement in accordance with  claim 1 , wherein segments ( 11 ,  12 ,  13 ) are turned on or off at least in alternating rows or in a checkerboard pattern.
