Abstract
The startup time or the output gradient of a gas turbine plant during startup are limited by the maximum permissible temperature gradient. The increase in the fuel mass flow supplied, if appropriate in combination with the combustion-air mass flow supplied, is consequently also limited. In order to accelerate the startup and to increase the output gradient during startup, then, an additional working medium, for example water or steam, increasing the mass flow flowing through the turbine is supplied at the same time as the fuel mass flow and/or combustion-air mass flow. The output gradient is therefore increased with the maximum permissible temperature gradient remaining the same, so that a required output is reached more rapidly.
