Title:
GASEOUS-FUEL ANALYZER AND SYSTEM FOR CONTROLLING GAS TURBINE
Document Type and Number:
WIPO Patent Application WO/2012/141252
Kind Code:
A1
Abstract:
A gaseous-fuel analyzer for determining properties of a gaseous fuel, the analyzer comprising: a gas chromatograph which measures the calorific value and specific gravity of the gaseous fuel and the concentration of a specific component therein and which outputs the measured values at a constant interval; a concentration meter which measures the concentration of the specific component in the gaseous fuel and outputs the measured value at a shorter interval than the gas chromatograph; and an arithmetic correction unit which corrects the measured values of the calorific value and specific gravity that were outputted by the gas chromatograph, on the basis of both the measured value of the specific-component concentration outputted by the gas chromatograph in the same period and the measured value of the specific-component concentration outputted by the concentration meter in the same period.
