摘　　要：以城市垃圾热解后的垃圾焦为原料,根据能量平衡、物料平衡和反应平衡的原理,建立了垃圾焦自热式流化床气化的平衡组成计算模型。利用该模型进行了模拟计算,得到了垃圾焦流化床气化过程的产品组成、火用效率,模拟了反应温度、氧气纯度、垃圾焦含碳量、水蒸气量及氧气预热温度对产品组成、火用效率的影响规律。Taking the waste coke after pyrolysis of municipal solid waste as raw material, a caleulation model of gasification equilibrium composition in waste coke self-heating fluidized bed is established according to the principles of energy balance, material balance and reaction balance. Through the simulation calculation based on the model, the product composition and exergy efficiency during gasification in waste coke self-heating fluidizcd bed are obtained. The influence of reaction temperature, oxygen purity,carbon content in waste coke, water vapor and preheating temperature of oxygen on the product composition and exergy efficiency is simulated.
