A flarestack burner tip has a Coanda body placed across the outlet of a high pressure gas line to form an annular slot from which the gas emerges and flows over the Coanda surface. The feed line is a pipe consisting of fixed and moveable parts, the moveable part partially enclosing the fixed part so as to form an annular space. A vertical bellows fits into the space, the upper end of the bellows being attached to the moveable portion of the pipe. Springs acting in series with the bellows may also be attached between the fixed and moveable pipe portions. |
