Thermogravimetric assessment of blended fuel for bituminous coal,miscellaneous wood pellets and oil sludge
摘要
Abstract
To investigate the combustion characteristics of a blended fuel consisting of bituminous coal,miscellaneous wood pellets,and oil sludge,thermogravimetric analysis is conducted on the blended fuel to analyze its combustion behavior.The FWO method is employed for kinetic analysis of the blended fuel.The results show that the combustion process of bituminous coal is primarily fixed carbon combustion,while the combustion process of miscellaneous wood pellets is more complex and exhibits the best combustion performance,with a comprehensive combustion characteristic index as high as 1.93×10-7.Co-firing with miscellaneous wood pellets effectively enhances the combustion performance of bituminous coal.When bituminous coal and miscellaneous wood pellets are blended in a mass ratio of 1∶4,the ignition temperature of the blended fuel decreases by 35%compared to bituminous coal alone.The comprehensive combustion characteristic index increases by 7.2%compared to miscellaneous wood pellets.The most probable function for the co-firing of bituminous coal and miscellaneous wood pellets is[-ln(1-α)]-3/4.When the blending ratio of miscellaneous wood pellets reaches 45%,the appropriate addition of oil sludge can improve the combustion performance of the fuel.The most probable function for the combustion reaction of the blended fuel consisting of all three components is[-ln(1-α)]2.When the blending ratios of bituminous coal,miscellaneous wood pellets,and oil sludge are 40∶40∶20 and 45∶45∶10,respectively,the corresponding activation energies of the blended fuel are significantly lower than those of other blending ratios,and the comprehensive combustion characteristic index is approximately 1.5 times that of pure bituminous coal.关键词
