Factory chimneys can be divided according to different classification standards, mainly including the following types:
Classification by material:
Brick chimneys: Made of bricks or brickwork, commonly found in residential and industrial plants. Brick chimneys have high high temperature resistance and corrosion resistance, and can be customized according to needs.
Reinforced concrete chimneys: mostly used for chimneys with a height of more than 50 meters, usually constructed with slipforms. Reinforced concrete chimneys have high strength and corrosion resistance and are widely used in modern buildings.
Steel chimneys: Made by welding or bolting steel plates, mainly used in industrial sites and power plants. Steel chimneys have a strong structure, good durability, and are easy to reinforce or disassemble.
Fiberglass chimneys: Made of fiberglass materials, they are light, corrosion-resistant and have a short construction period. They are suitable for a variety of industrial scenarios and do not require internal anti-corrosion treatment.
Stainless steel chimneys: Known for their excellent anti-corrosion properties, they are suitable for harsh environments. Stainless steel chimneys are light in weight, easy to transport and install, and are often used in high-rise buildings and industrial facilities.
Classification by structure:
Free-standing chimney: Directly fixed to the base through the bottom flange connection, no external support is required. The free-standing chimney has a simple structure and is suitable for a variety of scenarios.
Tower chimney: There is a tower as the main load-bearing structure on the outside, similar to a communication tower. The tower chimney is highly safe and suitable for occasions with a relatively large height and diameter.
Sleeve chimney: It consists of an inner and outer tube and is often used in power plants with a flue gas wet desulfurization system. Sleeve chimneys can effectively deal with the corrosiveness of flue gas after desulfurization.
Classification by use:
Industrial chimney: Mainly used to discharge industrial waste gas, usually tall and complex in structure. Industrial chimneys include tall chimneys, short chimneys and multi-functional chimneys, suitable for power plants, chemical plants, etc.
