摘要
Abstract
Combustion and sulfur retention experiments of mixed fuel of petroleum coke and coal were conducted on a pilot-scale circulating fluidized bed (CFB) combustor with the thermal input of 0.6 MW.The effects of several parameters,such as the primary air percentage,excess air coefficient,bed temperature,Ca/S molar ratio and mass ratio of petroleum coke to coal on SO2 emission were verified.Experimental results show that when the ratio of petroleum coke to coal in the mixed fuel increases,the SO2 emission increases.The maximum SO2 emission appears when pure coke burns.The SO2 concentration in flue gas reduces with the increase in the primary air percentage,excess air coefficient and Ca/S molar ratio for all kinds of fuel mixtures.The range between 830℃ and 850℃ is the optimal temperature for sulfur retention during co-firing of petroleum coke and coal with the mass ratio R of 1 and 3 in CFB.关键词
