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%.

The utilization of the biomass provides sustainable and environmentally¬ friendly benefits as well as the possibility of dispose of the industrial wastes safely and effectively, without harming the environment. Compared to the solid fossil fuels, biomass contains much more moisture and volatile which can affect profoundly the fuel handling and feeding systems; therefore, the conventional combustion technologies are inconvenient for the biomass fuels combustion. For solving these problems, technologies based on fluidized bed (e.g. circulating fluidized bed) can be considered as the most proper remedy for industrial combustion of solid biomass fuels. In this regard, firing of vegetable oil production industrial wastes (e.g. sunflower meal and hull) in a Circulating Fluidized Bed (CFB) can be an appropriate possibility for thermal energy generation. By applying this technology, removal of process waste can be achieved with minimum environmental effects, on the other hand, energy supply at an oil production facility can be based mostly on waste biomass, and therefore, there will be no need to fossil fuels. In this study, combustion of the waste of a typical sunflower oil production facility in a 0.1 MWth CFB combustor under 850¬880ºC of bed temperature is investigated. Combustor efficiency and concentration of O2, CO2, CO, NOx and CmHn in flue gas are recorded based on continuous measurement principle. Moreover, a non¬isothermal thermogravimetry analysis, in which the biomass sample is burned with O2 and is applied, in order to obtain the combustion characteristic of the sunflower meal. Performance results of the sunflower meal combustion in the Circulating Fluidized Bed Combustor (CFBC) are presented. These results suggest that combustion of sunflower meal in a CFB combustor can be utilized for clean and effective energy generation in sunflower oil production f [...]

The purpose was to determine and compare the performance of each type of lignite in the same gasifier. Exergy destruction of each component and exergetic performance of the overall plant was also investigated. In addition, CO2 emissions of each type of lignite were calculated. The results showed that Yenikoy lignite had the best performance among the different types of lignite, with 491 MW net power and 37.88% net exergy efficiency (without acid gas). It also had the minimum amount of CO2 emission at 726 kg/MWh. Therefore, Yenikoy lignite was chosen as a case study fuel and a detailed exergy analysis of its components was applied. The results showed that the major exergy destructions took place in the gasifier and the combustion chamber at 46.15% and 22.74%, respectively.

The subject of this study is technical and environmental investigation of the feasibility of the cofiring of Soma lignite with some dried agricultural residues in the Soma thermal power plant from the exergy analysis perspective, using THERMOFLEX simulation software. The use of biomass cofiring with poorquality coal could allow Turkey to comply with Kyoto commitments while benefiting from using indigenousfuel resources and reducing biomass waste disposal problems. Two technologies are considered; (1) direct cofiring, in which biomass is mixed with lignite in the same mill and fed into the boiler furnace and (2) parallel cofiring method, in which biomass is fired in a separate circulating fluidized bed boiler and produced steam is supplemented into the steam network of th...
