编写了焦炭塔空塔气速计算软件，并利用某装置实际生产数据，分别计算了生焦周期为24h和20h两种工况下空塔气速数值。计算结果表明，24h生焦平均气速为0．1395m／s，20h生焦平均气速为01494m／s，该装簧实际生产中空塔气速偏大。在空塔气速偏大的情况下，为保证安全生产，焦炭塔内所留安全空高余地过大，从而造成焦炭塔利用系数低。文章最后探讨了提高焦炭塔利用系数的可能性。%The software has been developed to calculate the vapor velocity on delayed coking drums. Based on the operation data of the delayed coking unit, the vapor velocity of two cases has been calculated. For the production cycles of 24 h and 20 h, the average vapor velocity is 0.1395 m/s and 0.1494 m/s respectively. The conclusions have provided that the vapor velocity is larger than the specified value. In order to ensure safety, the empty height is too large in actual production. Thus, the utilization factor of the coke drums is very low. Last, the measures of improving the utilization factor of the coke drums have been investigated.
