rökspjäll

Rökspjäll, also known as a damper, is a mechanical device used to regulate the flow of air or other gases in systems such as chimneys, flues, or ventilation ducts. It typically consists of a plate or valve that can be opened or closed to control the passage. In the context of a fireplace or wood-burning stove, a rökspjäll is crucial for controlling the draft. By partially or fully closing the damper, the user can reduce the amount of air entering the combustion chamber and subsequently slow down the burning process. This also helps to retain heat within the living space when the appliance is not in use, preventing warm air from escaping up the chimney.

The operation of a rökspjäll can be manual or automatic. Manual dampers are usually operated by a lever or handle accessible from the fireplace or stove. Automatic dampers, on the other hand, can be controlled by thermostats or other sensors that adjust the damper position based on temperature or gas flow. In some industrial applications, dampers are used in large ducts to control airflow for processes like heating, ventilation, and air conditioning (HVAC), or in exhaust systems to manage emissions. The material of a rökspjäll is typically metal, chosen for its durability and resistance to heat and corrosion. Proper installation and maintenance of a rökspjäll are important for the safe and efficient operation of the associated system.
