Steel chimneys are tall, slender, tapering structures having a circular cross section. They are best suited for process work where a small thermal capacity and quick heat-up time are needed. This page describes many steel chimney types and their designs.
The chimney is referred to as a self-supporting chimney when the lateral forces (such as wind or seismic pressures) are communicated to the foundation by the chimney’s cantilever action. Under all working situations, the self-supporting chimney and the base hold their stability without any external support. The self-supporting chimneys can be up to 10 metres in diameter and 50 to 100 metres tall.
Mild steel wire ropes or guys are attached to transmit lateral forces in high steel chimneys. Guyed steel chimneys are the name given to these steel chimneys. In guyed steel chimneys, the chimney shell does not entirely support all of the externally applied loads (wind, seismic energy, etc.). These imposed loads are shared by these attached guys or stays.
The guyed steel chimney is stabilised by these stays or guys. One, two, or three sets of guys may be included with these steel chimneys. Three, four, or occasionally six wires are hooked to the collars in each set of guys. When a single pair of guys is employed, the guys are fastened to a collar at a height of one-third to one-fourth from the top.
The Global steel chimney market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2022 to 2030.
SuperFlex Stainless Steel Chimney are designed for field installation into brand-new, pre-existing, tile-lined, or unlined masonry chimneys that are used to vent residential appliances that burn solid fuel and are Category I gas-fired, Type L oil-fired, or both.
The maximum continuous flue gas temperatures should not be higher than 1000°F. Chimneys are designed to be built in conformity with the “National Fuel Gas Code,” NFPA 54, and the “Standard for Chimneys, Fireplaces, Vents, and Solid Fuel Burning Appliances,” NFPA 211.
