Steel Chimney Systems
With the development of the industry, the construction of steel chimneys started to gain momentum. Since steel chimneys have more advantages over concrete chimneys, they have become preferred especially in applications where chimney heights are increased. Steel chimney systems can be made in various constructions, in the same external geometric shapes and sizes, according to their intended use. In this study, the latest technological developments are evaluated by considering the types, design, project preparation, manufacturing and application areas of the steel chimneys that have become widespread.
In the rapidly developing chimney sector, companies are fighting fiercely to produce efficient, economical and environmentally friendly systems. In this process, chimneys are needed to discharge the smoke gases formed as a result of combustion into the atmosphere in order to generate energy in burning devices. Especially in industrial boiler applications, besides the efficient operation of the system, fire and structural stability and similar aspects of the chimney;
1- Determination of its cross section,
2- Determining the height,
3- The choice of material,
Steel Chimney Design Systems
Steel chimney; It is a construction material that safely throws the smoke gases that occur as a result of combustion into the atmosphere or provides the fresh air required for the combustion of industrial waste gases.
Chimneys of industrial boilers and facilities can be made of steel, concrete and brick. In recent years, brick chimney applications have disappeared except for special processes. Section and height calculations of steel chimneys are made according to TS EN 13384-1 and TS EN 13384-2, manufacturing and assembly according to TS EN 13084-7 and Eurocode 3 standards. In addition, in our country, the “Industrial Air Pollution Control Regulation” must be taken into consideration regarding industrial chimneys.
As the inside of the chimney heats up quickly, it provides rapid traction.
- Chimney friction loss is low as the inner surface of the chimney is not rough.
- Since the wear problem is very low, high flue gas velocities can be reached.
- It can be manufactured in small diameters.
- There is no possibility of leakage.
- As the inside of the chimney heats up quickly, it provides rapid traction.
Disadvantages of Steel Chimneys
- It is not resistant to outdoor conditions like concrete and brick chimneys.
- It is not resistant to corrosion. It requires extra processing. Sandblasting, painting etc.
