Abstract

The present invention refers to a burner arrangement for burning combustible gas supplied, for example, by a blower (1), in which case the burner arrangement has at least one gas supply pipe (2) for supplying the gas to be burned, in which case the burner arrangement comprises a nozzle arrangement (3) placed downstream from the gas supply pipe (2) in an intended flow direction (S) of the gas, in which case the nozzle arrangement (3) has one or several gas outlet openings (5) through which the gas to be burned can flow out from the nozzle arrangement (3) before it is burned, and in which case the gas outlet opening(s) (5) has/have a total gas outlet area. According to the invention, it is provided for the burner arrangement to comprise means used to change the total gas outlet area of the nozzle arrangement (3) within defined limits so the flow speed of the gas flowing out of the gas outlet opening(s) (5) can be regulated. Furthermore, a method for operating a corresponding burner arrangement is suggested, characterized as a result of this that the total gas outlet area of the nozzle arrangement (3) is adjusted in such a way while the burner arrangement is operating that the flow speed of the gas flowing out through the gas outlet opening(s) (5) always stays within defined limits.

Claims

1. Burner arrangement for burning combustible gas supplied, for example, by a blower (1),

in which case the burner arrangement has at least one gas supply pipe (2) for supplying the gas to be burned,

in which case the burner arrangement comprises a nozzle arrangement (3) placed downstream from the gas supply pipe (2) in an intended flow direction (S) of the gas,

in which case the nozzle arrangement (3) has one or several gas outlet openings (5) through which the gas to be burned can flow out from the nozzle arrangement (3) before it is burned, and

in which case the gas outlet opening(s) (5) has/have a total gas outlet area, characterized in that the burner arrangement comprises means used to change the total gas outlet area of the nozzle arrangement (3) within defined limits so the flow speed of the gas flowing out of the gas outlet opening(s) (5) can be regulated.
