ABSTRACT:
A process for regulating gas pressures of a regenerator with a gas expansion turbine in a flue gas line with a generator, wherein a process regulator opens the inlet valves of a gas expansion turbine and/or the bypass valves or throttles the bypass valves, doing so once with operation and once without operation of the gas expansion turbine. The process regulator is followed by a plurality of function generators, which preset the correcting variables for the downstream valves and in which a first function course of the function generators for operation of the gas expansion turbine and a second function course of the function generators for operation without gas expansion turbine are stored. A quick-acting valve of the inlet valves is acted upon by the speed regulator and it is active only at the time of the start-up of the gas expansion turbine until synchronization of the generator.
