Scope of application of industrial chimney systems (self-standing sleeve steel chimneys, self-standing single-cylinder steel chimneys, clustered steel chimneys, tower chimneys, fiberglass chimneys, etc.): Waste incineration industry, light industry, coal industry, self-powered small power plants and other fields. Sleeve free-standing steel chimney: The sleeve self-standing steel chimney adds an anti-corrosion inner cylinder inside the single-cylinder type. Commonly used anti-corrosion inner cylinder materials include SUS304 stainless steel, 2205 duplex stainless steel, fiberglass, titanium steel composite panels and other materials. The specific materials are selected according to the project flue gas composition and chimney temperature. At the same time, there is insulation cotton between the inner and outer cylinders to effectively ensure chimney emissions and reduce the smoke dew point. ； The outer cylinder of the sleeve self-standing chimney bears the structural load, and the inner cylinder bears the corrosion protection. The deformation of the cylinders is coordinated to prevent internal stress in the structure. At the same time, the sleeve self-standing chimney has the characteristics of small area and short construction period. The production and installation period of a 100-meter chimney does not exceed 3 months. At present, our sleeve self-standing chimneys can be built up to a height of 130 meters. Single tube self-standing steel chimney: The single-cylinder type has only one layer of cylinder material. The cylinder material is usually Q355B material. The cylinder must not only ensure the structural load, but also ensure the anti-corrosion of the inner cylinder (the inner wall of the cylinder can be sprayed with anti-corrosion paint) ； Suitable for heights not exceeding 50 meters ； Chimney with low corrosive flue gas and low flue gas temperature ； Tower steel chimney: The inner tube material of the tower-type steel chimney can also be designed with SUS304 stainless steel, 2205 duplex stainless steel, fiberglass, titanium steel composite plate and other materials. At the same time, the outside can be designed with insulation cotton and outer protective board. The cylinder is supported and sway-stopped by the tower, and the tower protects the cylinder. The main features of tower-type steel chimneys are high cost performance and high buildable height. We can currently reach a height of 180 meters. With the requirements of de-industrialization, tower chimneys with external decoration are also the first choice for de-industrialization. Towers with external decoration can meet customer requirements. Clustered steel chimney: Clustered steel chimneys are multiple self-standing chimneys connected through trusses, and the overall structure is more stable. It is mainly used for multiple smoke emissions and takes into account aesthetics. The height of cluster chimneys can reach 150 meters, and multiple chimneys use a set of ladders.
