Understanding Cupolas: Function, Materials, and Design Considerations

Cupolas are small towers or structures that are built on top of a blast furnace, steel mill, or other industrial equipment. They are used to provide a ventilation path for gases and particles that are produced during the process, allowing them to be removed from the facility and released into the atmosphere.

Cupolas can be made of various materials, such as brick, stone, or metal, and can range in size from a few feet to over 100 feet tall. They are typically equipped with a chimney or stack that extends above the structure, which helps to direct the gases and particles away from the facility and into the atmosphere.

In addition to providing ventilation, cupolas can also serve as a visual indicator of the type of process being conducted within the facility. For example, a blast furnace cupola may be painted with a distinctive color or design to indicate the type of metal being produced.

Overall, cupolas play an important role in ensuring the safe and efficient operation of industrial facilities by providing a means for removing harmful gases and particles from the process.
