0　前言过去曾有报导 ,循环流化床锅炉内燃烧石油焦会引起旋流分器沉积物及返料腿封堵问题。本文提供的试验数据资料表明 ,在这些问题中 ,有一些是由在燃烧期间采用的含钙丰富的流化床床料引起的。以前 ,我们就已证实氧化钙可以与烟气中的二氧化硫 (ＳＯ2 )和二氧化碳 (ＣＯ2 ) 0 Foreword It has been reported in the past that burning petroleum coke in a circulating fluidized bed boiler can cause plugging of the cyclone separator deposits and return legs. The experimental data provided in this paper show that some of these problems are caused by the bed of calcium-rich fluidized bed material used during combustion. In the past, we have demonstrated that calcium oxide can react with sulfur dioxide (SO2) and carbon dioxide (CO2)
