Abstract
A chimney section and a chimney system for handling gases is disclosed. The chimney section is rounded but non-circular in cross sectional shape and includes at least one flange on one end of the section body. The chimney section may be formed from a single piece of material, wherein the section body and flange are integrally formed with one another. In the chimney system, the junction between two adjacent chimney sections may consist of a flange interface, which is formed by the adjacent flanges on opposing ends of two adjacent chimney sections. A V-band may be placed over the flange interface to further seal the interior of the chimney sections, and a sealant may be placed in various positions of the chimney system to hermetically seal the interior thereof from the exterior. In another embodiment of the chimney system, insulation is added to create an insulated chimney system.
