The wall (5) of a tube (2) for delivering pulverised fuel to the outlet (4) of an oxy-fuel burner (1) forms part of a chamber (6) which is pressurized or evacuated. The pressure in the chamber is continuously monitored. If the pressure in the chamber (6) changes in a way indicative that the wall (5) of the oxy-fuel burner (1) has failed the oxy-fuel burner (1) is automatically shut down.
