Abstract (en)

[origin: EP0683356A2] The process is for a chamber into which hot gas flows. Fuel (8) is blown into the hot gas over several fuel flanges (9). Self-ignition then occurs. The fuel flanges are divided into at least two groups which are supplied with gas consecutively. The supply of hot gas to the groups remain constant. The flanges are heated to a temp. in the region of 1100 degrees C. All the flanges are connected up and their temp. is raised in parallel to the required operation temp. Supporting air (10) may be supplied to the flanges along with the fuel. <IMAGE>
