An approach to enhance combined cycle performance by integration with a gas pressure reduction station
Abstract
A novel system enhancing the performance of a combined cycle gas turbine has been proposed in the paper, basedon the example of the thermal-electric power station currently under construction in Włocławek. Analysis shows thatannual average electrical eciency rises by 0.6% and that power output rises by up to 4%, depending on the ambientconditions. GE’s GateCycle software was used in the modeling.References
