Abstract:
According to the IEA reports, Turkey generates approximately one-third of its total electricity from low grade lignite type of coal with limited reserves and high environmental impacts. In this regard, co-firing of lignite with sustainably-grown biomass in circulating fluidized bed (CFB) can be an unavoidable possibility for operating power plants with alternative local renewable sources and reducing their emissions. This study deals with the technical and environmental investigation of co-combustion of Çan lignite with some dried agricultural residues such as corn cobs, cotton gin, hazelnut shells and olive and rice husk in the first and only circulating fluidized bed power plant (CFBPP) of Turkey. In this regard, THERMOFLEX software was utilized to simulate the power plant and make a parametric analysis to investigate the impact of variations of the biomass/lignite ratio on the technical and environmental performance of the system. The results show that total NO2, SO2 and dust emissions of the power plant decreased significantly, when biomass is used. Furthermore, it has been observed, that the increase of the fraction of the all investigated biomasses from 0 to 40% can increase the efficiencies around 2%.
