摘要

A method for operating a gas - and steam turbines force works is provided with integrated coal gasification, consisting of a coal gasification plant (1), a gas conditioning system (3), a gas turbine plant (15) with a gas turbines as a rule, the valve (14) and a steam turbine plant (16), wherein a burnable gas flow (2) for gas turbines as a rule, the valve (14) and a branching partial stream (5) to at least one external utilization (7, 8) are guided, characterized in that the average size of the mass flow of the branching partial stream (5) within a range of the 1,5 to 5fachen of the average stochastic masses current fluctuations of the fuel gas flow (2) according to the gasification plant (1) is set and the instantaneous magnitude of the mass flow of the branching partial stream (5) the instantaneous stochastic masses current fluctuations of the fuel gas flow (2) according to the gasification plant is adjusted to the instantaneous stochastic heating value of current fluctuations of the fuel gas flow (2) in front of the gas turbines valve (14) as a rule, in percentage terms are smaller than the instantaneous stochastic masses current fluctuations of the fuel gas flow (2) according to the gasification plant (1).
