摘要 在循环流化床实验台上对石油焦的结焦特性进行了实验研究。研究结果表明 :石油焦属易结焦燃料 ;结焦的发生受床温、空塔速度、烟气中物料浓度以及受热面壁温的影响 ,较高的空塔速度和物料浓度有助于避免结焦。在相同的操作条件下 。 An experimental study was conducted of the agglomeration characteristics of petroleum coke on the test rig of a circulating fluidized bed. The results of the study show that the petroleum coke pertains to a kind of fuel liable to agglomeration. The agglomeration occurs under the influence of the fluidized bed temperature, fluidizing speed, the concentration of materials in the flue gas and the wall temperature of heating surfaces. A relatively high fluidizing speed and material concentration will be conducive to preventing agglomeration. Under the same operating conditions the sum of the minimum wall temperature of agglomeration and the fluidized bed temperature tends to be a constant.
