双塔精馏炉是葫芦岛锌厂的干部、技术人员、工人的共同创造,它是在不增加多少基建费用,不必扩大原厂房面积的条件下,使精锌产量翻了一番。它为蒸馏锌产量正不断增长的葫芦岛锌厂需要配套增产精锌做了卓越的贡献。但是,双塔精馏炉这个新事物和其他事物一样,也存在着一些缺点,主要的有:双塔体间的中间燃烧室结构不很合理(见图1);中 Twin tower distillation furnace is the co-creation of cadres, technicians and workers in Huludao Zinc Plant. It doubled the production of refined zinc without increasing the capital cost and without expanding the original factory area. It is an excellent contribution to the need to support the production of refined zinc for Huludao Zinc Plant, which has a growing output of distilled zinc. However, the new thing of the double-column distillation furnace, like other things, has some shortcomings. The main ones are: the structure of the middle combustion chamber between the two towers is not very reasonable (see Figure 1);
