Rökgångs

Rökgångs is a Swedish term that translates to "smoke passage" or "flue" in English. It refers to a channel or conduit designed to convey smoke, gases, and heat away from a heat source, such as a fireplace, stove, or industrial furnace, to the outside atmosphere. These passages are crucial components of heating systems and industrial processes to ensure safe and efficient operation.

The construction of a rökgångs can vary depending on its intended use and the type of heat source. In residential settings, they are typically made of brick or stone and are an integral part of a chimney. The internal dimensions and shape are designed to create a draft, which is the upward movement of air and smoke caused by the difference in temperature and density between the hot gases inside the flue and the cooler air outside. This draft is essential for drawing combustion byproducts away from the living space and preventing the buildup of hazardous gases like carbon monoxide.

In industrial applications, rökgångs can be much larger and constructed from materials like steel or refractory ceramics to withstand higher temperatures and corrosive substances. They are used in a wide range of industries, including power generation, manufacturing, and waste incineration, to manage emissions and recover heat. Proper maintenance of a rökgångs is vital to prevent blockages, which can lead to inefficient operation, fire hazards, and the release of pollutants. Regular cleaning and inspection are therefore recommended.
