作为重沸器的降膜蒸发器由于其液体保持能力有限而支持蒸馏塔的轻松调节及快速启动和关闭。它也适合以非常小的温差运行。
因此，降膜重沸器用于温度敏感产品，特别适用于节能、多效的蒸馏工艺。
强制循环重沸器用于残留产物中预期存在粘稠和/或严重污染介质的重沸器任务。
管路中的高液体速度和所产生的剪切力可确保这种类型的热交换器在其最佳性能范围内运行，同时将结垢保持在最低水平。泵的选择影响性能和效率。强制循环重沸器可以设计为水平或垂直安装。
热虹吸重沸器在投资成本和运行成本方面最具吸引力，但是需要工艺条件非常稳定并允许高温差。由于对工艺的要求较高，因此其应用受到限制。在具有多效蒸馏装置的现代节能理念中，通常很少使用热虹吸。
