dc.description.abstractOxy-fuel combustion is a promising technology for the reduction of carbon dioxide emissions, in coal-fired power plants that allowthe clean use of fossil fuels. Circulating fluidized bed (CFB) boilers are one of the power generation technologies that can use oxyfuel combustion design successfully. The purpose of this paper is to perform the techno-economic feasibility analysis of thecommercial-scale oxy-fuel combustion circulating fluidized bed (oxy-CFB) power plant generating 550 MWe net power with acarbon capture rate of 90%. So far, economic analysis of oxy-PC power plants has been studied by researchers at many reports.Nevertheless, the cost of an oxy-CFB power plant has rarely been studied.This is the first study that has used Turkish lignite(Orhaneli Coal) in an oxy-CFB carbon capture plant economic analysis. The basic economic performance indicators wereinvestigated. The Models are based on cost scaling and Discounted Cash Flow analysis. Three cases were analyzed: In the firstcase, A base scenario (air-fired CFB plant without CO2 capture) is considered and then based on this baseline scenario the otherscenarios are taken into account. The economic viability of transition from the classical air-fired CFB plant system to oxy-CFBwith CO2 capture and compression plant is evaluated. The post-combustion monoethanolamine (MEA) based CO2 capture systemis investigated as a benchmark study to compare oxy-CFB capture system performances. The main applicability parameters suchas cost of electricity (COE), levelized cost of electricity (LCOE) and the cost of CO2 capture for each case are calculated. Theobtained results indicated that 54% and 52% increase in terms of total plant cost and COE respectively in the oxy-CFB plant whencompared to air fired-CFB without carbon capture. Considering the COE, the designed oxy-CFB power plant is greater than theair-fired SC-PC (without capture) plant by more than 45% (DOE target). The efficiency penalty for oxy-CFB is 10%. Oxy-CFBplant has a net efficiency 2% point higher than amine-based CO2 capture systems. In amine-based CO2 capture system; The capitalcosts, LCOE, and cost of CO2 captured are higher than the oxy-CFB plant. The results show that the oxy-CFB power plant has alower cost for carbon capture compared to amine-based capture plant.en_US
