Abstract: The invention relates to a method for controlling a gas turbine, operating with an integral fuel reactivity measurement concept. In order to fast determine a safe operation range of the gas turbine with respect to flashback and blow-out, the method includes deducing the fuel composition and therefore the fuel reactivity by combined measurements of (n−1) physico-chemical properties of a fuel mixture with n>1 fuel components, for deriving the concentration of one component for each physico-chemical property of the fuel gas mixture or for determining of a ratio of the fuels with known compositions and adjusting at least one operation parameter of the gas turbine at least partially based on the determined property of the fuel gas mixture entering the combustors. With the technical solution of the present invention, by way of detecting fast changes in fuel gas, it is assured that the gas turbine may operate with varieties of fuel gas under optimized performance and in safe operation ranges. In actual applications, the present invention may improve flexibility of gas turbines and cost effectiveness of operation of the gas turbines.

Abstract: A method is provided for measuring the mass flow of a stream of a gaseous medium of elevated first temperature flowing through a specific pipe. The method includes providing a reference stream of the gaseous medium with a known mass flow and a second temperature being substantially lower than the first temperature. The method further includes mixing the reference stream with said stream of a gaseous medium of elevated first temperature flowing through said specific pipe. The measure resulting temperature of the mixture of the reference stream and said stream of a gaseous medium of elevated first temperature flowing through the specific pipe is measured. The method further includes determining the unknown mass flow of the stream of a gaseous medium of elevated first temperature flowing through the specific pipe from the known mass flow of the reference stream; the elevated first temperature, the second temperature of the reference stream and the measured resulting temperature according to the formula: Mx = M ref  ( T   1 - T   3   x ) ( T   3   x - T   2 ) , where Mx is the unknown mass flow, Mref is the known mass flow of the reference stream, T1 is the second temperature, T2 is the elevated first temperature, and T3x is the resulting temperature after mixing.
