Efektywność ekonomiczna układu gazowo-parowego zintegrowanego ze zgazowaniem wȩgla oraz z instalacja̧ CCS

In this article the economic efficiency of an IGCC power plant was analyzed. This system consists of a gas generator, CO₂ membrane installation (CCS) and a combined cycle. The investment cost was assumed for the selected IGCC systems integrated with the CCS installation. The basic indicators of economic analysis were determined. For the conducted analysis it is essential to determine the break-even price of electricity, as well as the cost of CO₂ avoided emission. The effect of changes of the efficiency of the system and the auxiliary power rate on the price of 1 MWh of electricity was analyzed. Also, the effect of the availability, the investment cost, the price of fuel, the cost of individual elements and the size of macroeconomic factors was analyzed.
