Abstract:
1. A method of operating a thermal power plant in which a rotary unit is driven by burning gaseous fuel inside a combustion chamber, with hot gases being formed, the rotary energy of which rotary unit is converted into another form of energy, and describes a load set point (L) of the thermal power plant, the load set point (L) being set by regulating the quantity of gaseous fuel fed to the combustion process, wherein the thermal power plant is operated at a load set point (L), provided the gaseous fuel is fed to the combustion process through a gas line at a gas pressure p where p wherein, starting from an initial load set point L i) the standard deloading is ended and the thermal power plant is changed to its initial load set point, or ii) complete emergency load shedding is carried out, during which the fuel reduction is carried out more rapidly than during the standard deloading, or iii) the fuel supply is changed over to another type of fuel.
