A process and device for the reliable monitoring of the current condition of the protective jacket formed of fireproof material, in particular of a rotary tubular kiln burner lance, during operation of the kiln system. A compressed air ring main and/or an annular metal wire loop forming part of an electrical circuit extending around the circumference of the protective jacket are embedded in the fireproof compound of the protective jacket in the area of the burner tip, in which in the event of burning through of the ring main or metal wire loop, a connected pressure sensor or current sensor generates a monitoring signal.

The invention claimed is: 1. A process for monitoring the condition of a protective jacket of a burner, which comprises fireproof material, and in particular a burner lance for firing of a rotary tubular kiln for the production of cement clinker from raw powder, comprising the steps of embedding a ring main extending around a circumference of the protective jacket in the fireproof material of the protective jacket in an area of a burner tip, and generating a signal in the event of damage to the protective jacket or the ring main at any point on the circumference. 2. A process in accordance with claim 1, wherein the ring main contains air at over-pressure, and wherein in the event of damage to the protective jacket and the burning of the tubular ring main at any point on the circumference, a pressure sensor measures a drop in air pressure and generates the monitoring signal. 3. A process in accordance with claim 1, wherein the ring main embedded in the protective jacket is an annular metal wire loop which forms part of an electrical circuit, and wherein in the event of damage to the protective jacket and burning through of the metal wire loop, the electrical circuit is broken and the monitoring signal generated. 4. A device for monitoring the condition of the protective jacket of a burner, which comprises fireproof material, and in particular a burner lance for firing of a rotary tubular kiln for the production of cement clinker from raw powder, comprising: a compressed air ring main, or an annular metal wire loop forming part of an electrical circuit, extending around a circumference of the protective jacket being embedded in the fireproof material of the protective jacket in an area of a burner tip, and a connected pressure sensor or current sensor arrangement to generate a monitoring signal in the event of burning through of the ring main or metal wire loop. 5. A device in accordance with claim 4, wherein the metal wire loop comprises iron fuse wire. 6. A process for monitoring the condition of a fireproof material protective jacket of a burner lance having a burner tip at one end, comprising the steps of embedding a ring main extending around a circumference of the fireproof material of the protective jacket in the area of the burner tip, and generating a monitoring signal in the event of damage to the ring main at any point on the circumference. 7. A process according to claim 6, further comprising the steps: introducing air at over-pressure into the ring main, sensing a pressure drop, with a pressure sensor, in the ring main in the event of damage to the tubular ring main at any point on the circumference, and generating a monitoring signal in the event of a sensed pressure drop. 8. A process according to claim 6, further comprising the steps: providing an annular metal wire loop in the ring main to form part of an electrical circuit, sensing a current drop through the wire loop, in the event of damage to the wire loop, and generating a monitoring signal in the event of a sensed current drop. 9. A device for monitoring the condition of a protective jacket of a burner formed of fireproof material, comprising: a circuit comprising one of a compressed air ring main forming part of a gas circuit and an annular metal wire loop forming part of an electrical circuit extending around a circumference of the protective jacket, being embedded in the fireproof material of the protective jacket in the area of a tip of the burner, and a connected sensor arranged to generate a monitoring signal in the event of damage to the circuit. 10. A device according to claim 9, wherein the circuit is an air ring main and the connected sensor is a pressure sensor. 11. A device according to claim 9, wherein the circuit is a metal wire loop and the connected sensor is a current sensor. 12. A device according to claim 9, wherein the metal wire loop comprises iron fuse wire.
