Abstract

In a process for operating a fuel fired reactor fuel is introduced into a reactor and burned therein by means of at least one main burner. The relevant parameters of the process are monitored and the main burner is shut down if one or more of the relevant parameters leave a predetermined critical operating range. Within the predetermined critical operating range for the enforced shut down a secondary more stringent operating range for the shut down criteria is implemented and the main burner is shut down if one or more of the relevant parameters leaves the secondary operating range while at least one pilot burner continues to be operated as long as the relevant parameters are maintained within the critical operating range.
