Abstract:
A process for controlling the length of the flame during the combustion of a fuel in a burner, the burner including an injector, which injector includes at least an inner first oxidizer feed passage, an intermediate fuel feed passage externally surrounding the inner first oxidizer feed passage, and an outer second oxidizer feed passage externally surrounding the fuel feed passage, the process comprising the steps:supplying the fuel feed passage with fuel so that the velocity of the fuel exiting this passage is between approximately 1 and 15 ml/s;supplying oxygen to both the inner first oxidizer feed passage and the outer second oxidizer feed passage; andregulating the step of supplying oxygen between the inner first oxidizer feed passage and the outer second oxidizer feed passage to regulate the length of the flame.
