Method for on-line measurement of fuel heat content of fuel in a combustion turbine system

摘要

The fuel heat content of fuel is measured on-line while a combustion turbine system is running by measuring data from the combustion turbine system during combustion of the fuel. The measured data are corrected using a standard correction algorithm. The fuel heat content of the fuel is determined using at least a portion of the corrected data. From the measurement of the fuel heat content, any changes in the fuel heat content are determined. Also, any changes in the control and operational parameters attributable to the change in fuel heat content are determined.
