重整装置自然循环余热锅炉设计

Design of HRSG of natural circulation in catalytic reforming unit

炼油厂重整装置四合一炉对流段余热锅炉水力循环通常采用强制循环方式,目前还没有采用自然循环的先例。青海油田格尔木炼油厂重整装置在改造过程中将原来的强制循环余热锅炉改造为自然循环余热锅炉,减少了强制循环泵的设备投资和维修工作。阐述了余热锅炉自然循环计算方法及注意事项,证明了自然循环余热锅炉在重整装置应用的可行性,对装置内余热锅炉设计有一定的指导意义。

Forced circulation is generally applied in the HRSG of catalytic reforming unit in the refinery, and no natural circulation has been practiced up to now.In the revamp of catalytic reforming unit in Golmud Refinery,Qinghai Province,the forced circulation of HRSG was retrofitted to the natural circulation.The successful application of natural circulation was a breakthrough in HRSG and has reduced the capital investment and maintenance costs of forced circulation pumps in HRSG.The calculation method of natural...
