| 摘 要： | 催化裂化四机组的正常连续运转是保证装置合理经济运行的关键，其中烟气轮机的效率下降情况需要定期标定．本文利用功率平衡方程，提供一个简单易行的现场标定方法，并针对某炼厂运行的四机组进行了核算，证明这种方法具有一定的精确度，可用于四机组运行中各单机功率的平衡计算．指出影响四机组效率的主要因素是操作的正确性和稳定性，特别是再生器操作压力和烟气入口温度．烟气轮机没有必要年年标定，通常的做法是第三年同一时间标定，标定后和标定前功率之比即为功率下降率．

| Abstract: | The efficiency of catalytic cracking flue gas energy recovery device is required being periodically calibrated.By means of power equilibreum equation,a simple and convenient on side calibration method is put forward.The efficiency of the flue gas turbine in the catalytic cracking device in a refinery is calibrated by the method.Compared with actual recovery efficiency ,the calibration result is of high accuracy.It is held that it is necessary to calibrate the devices every two years.It is pointed that correct and stable operation is the key factor influencing their efficiency. |
