研究了煤热解分级利用多联产工艺产生的热解废水的循环流化床焚烧处理工艺。能量平衡计算结果表明，热解废水进入循环流化床燃烧炉，炉膛温度下降7.6℃。数值模拟了热解废水喷入流化床燃烧炉不同位置的4种工况，各工况炉膛出口温度均下降约16℃，2种计算方法虽有一定偏差，但误差在工程可控范围内。研究结果表明，热解废水送入循环流化床燃烧炉内焚烧的方案可行，能实现热解废水零排放。

The circulating fluidized bed (CFB) process for treating with pyrolysis wastewater from coal pyrolysis based polygeneration process is studied.According to calculation results of energy balance, the furnace temperature will drop by 7.6℃ when pyrolysis wastewater is sent into CFB furnace.Four working conditions at different locations where the pyrolysis wastewater is sprayed into the furnace are calculated by Fluent software for numerical simulation.The result shows that the furnace exit temperature has a reduction of 16℃ regardless of wastewater inlet location.Although certain deviation exists between two calculation methods, but the error is controllable.The research results show that the incineration of pyrolysis wastewater in CFB is feasible, which can help to realize zero discharge of pyrolysis wastewater.
