Flue is a duct, pipe, or channel designed to convey exhaust gases, smoke, or steam from a fireplace, furnace, boiler, or generator to the outdoors. In architectural and engineering contexts, flues are integral components of heating, ventilation, and combustion systems, serving to safely remove harmful byproducts and maintain proper air circulation. The design and construction of flues involve careful consideration of materials, dimensions, and configuration to ensure efficient operation and compliance with building codes and safety regulations. Factors such as the type of fuel being burned, the appliance's heat output, and the building's layout influence the flue's specifications. Proper flue sizing and installation are critical to prevent issues like inadequate draft, condensation, and the potential for dangerous gases to leak into living spaces. Regular maintenance, including cleaning and inspection, is essential to ensure the flue's ongoing functionality and safety. Advances in flue design and materials have led to the development of more efficient and versatile systems, such as double-wall and flexible flues, which offer enhanced insulation, corrosion resistance, and ease of installation in a variety of applications.
