摘　　要：通过TEC大颗粒尿素造粒装置在越南金瓯化肥厂的试车到平稳运行的实际操作,得出了甲醛加入点为尿液泵P106入口是比较理想的位置;造粒机多孔板孔径偏大时需要加快颗粒在造粒机内的水平运动,防止颗粒滞留时间过长产生包裹式结块;在空气湿度较大的地区应用时流化风温度需提高,但第一室流化风温度不宜超过90℃。Based on stable operation of the TEC urea granulation unit testing in Vietnam Jinou Fertilizer Plant, some conclusions are got： the molten urea pump P106 entrance is the ideal location for adding formaldehyde; it is need to accelerate the urea particles horizontal movement if the granulator porous plate aperture bigger than normal, which is to prevent the particles residence time so long in the granulator to form wrap caking; the fluidization air temperature should not exceed 90 ℃ when the TEC technology applied in the humidity area.
