摘要
In the paper the results of calculations of the gas turbine powered with gaseous fuel of different characteristics in relation to the designed fuel are shown. The main aim of the researches was to obtain the basic characteristics for gas turbine supplied with gas, which is a product of gasification and cleaning, carried out in the IGCC system integrated with CCS installation. In order to obtain the characteristics of the main quantities own computational algorithm was used. In the paper the main relationship that were implemented into the algorithm are shown. During the analyses the composition of the gaseous fuel was gradually changed and such quantity as efficiency and power of a gas turbine, stream of compressed air and exhaust gas temperature were observed. In addition, the developed algorithm allows for the determination of the index of the amount of air used for cooling of the expander blades. The change of this air flow is required to maintain safe operation at the changed condition of flow in the expander. In the paper the influence of the degree of integration of the gas turbine installation with air separation unit was also analyzed.
