Patent ID: 8197248

Claim:
A method for the selective safety-related monitoring of high-power entrained-flow gasification reactors with single- or multi-burner arrangement for the autothermic partial oxidation of fuels processed into pulverized fuel, with a gasification agent containing oxygen at operating pressures of up to 80 bar, comprising: integrating a gasification process monitoring system in a control system for the safe operation of the reactors, the gasification process monitoring system configured in two levels, wherein the first level ensures the monitoring and control of the fuel burner, wherein the second level the ignition, monitoring and control of the ignition and pilot burner, wherein when a fault that endangers the equipment is recognized the method further comprises initiating a second shutdown sequence, wherein the second shutdown sequence shuts down the ignition and pilot burner in addition to stopping the fuel gasification process, the second shutdown sequence includes safely disconnecting all media and ensures that the plant is safe by depressurizing the system, wherein when a fault occurs which triggers the shutdown sequence for the ignition and pilot burner the sequence for stopping the fuel gasification process is likewise started by logic connections, and wherein faults that endanger the equipment pertain to pressure and temperature exceeding limit values.
