Assuming the structure of the system and the power rating of a combined cycle, the consumption of the synthesis gas for chemical production makes it necessary to supplement the lack of synthesis gas used for electricity production with the natural gas. As a result a change of the composition of the fuel gas supplied to the gas turbine occurs. In the paper the influence of the change of gas composition on the gas turbine characteristics is shown. In the calculations of the gas turbine the own computational algorithm was used. During the study the influence of the change of composition of gaseous fuel on the characteristic quantities was examined. The calculations were realized for different cases of cooling of the gas turbine expander’s blades (constant cooling air mass flow, constant cooling air index, constant temperature of blade material). Subsequently, the influence of the degree of integration of the gas turbine with the air separation unit on the main characteristics was analyzed.}, type={Artykuły / Articles}, title={Analysis of operation of the gas turbine in a poligeneration combined cycle}, URL={http://journals.pan.pl/Content/94477/PDF/09_paper.pdf}, doi={10.2478/aoter-2013-0034}, keywords={gas turbine, Integrated gasification combined cycle, thermodynamic analysis, Natural gas and syngas fuel mixture, Change of load}, }
