[Summary description] The tower chimney takes the external tower as the main load-bearing capacity, just like the communication tower, the inner tube of the chimney is fixed on the tower, so it is called "tower-type chimney". Its characteristics are that the floor area is higher than that of the self-standing chimney, the cost is relatively high (not too much), the safety is high, and the height-diameter ratio is higher. Tower chimneys need to stand by gravity and therefore require tower support. The advantages are simple and firm, low cost, customizable tower models, more beautiful and practical. Compared with self-supporting chimneys, it is more stable and can definitely be more effectively affected by various bad weather. Then, let's learn about the advantages of lower tower chimneys!

Compared with self-supporting chimneys, it is more stable and can definitely be more effectively affected by various bad weather. Then, let's learn about the advantages of lower tower chimneys! The tower chimney is a large industrial chimney, which is composed of various forms such as tube-in-barrel, binoculars, three-barrel to four-barrel. Chimneys are generally large in diameter. For example, in the case of a 300WM unit, the diameter of a single simple tube is between 4.5-5m, and the diameter of a single tube of a 600WM unit is between 6-7m. The tube is in the form of a clustered steel inner tube. Features of tower chimney: Compared with other forms of chimneys, tower chimneys have high cost, long construction period, and certain requirements for floor space, which are suitable for large and medium-sized factories; The area and shape of the top of the chimney of the tower are determined by the temperature of the flue gas, the volume of the flue gas, the outflow velocity of the flue gas and the rising height of the flue gas; The clean space between the outer cylinder and the inner cylinder must have installation space, and there must be spaces and holes for the steel inner cylinder to enter in sections; The tower chimney must be able to withstand extreme temperatures, be able to withstand the chemical corrosion of the flue gas, including steady-state and transient changes, and be able to withstand the abrasion of particles in the flue gas flow, and the inner tube must be left with a certain thickness. The fixing bolts of the tower chimney are respectively welded on the basic steel structure, and the distance distribution is reasonable and even. The installation of the steel chimney uses a large crane. When connecting the chimney barrel and the foundation screws, use double nuts to fix it. When the chimney is hoisted to a suitable position, pull up the wind rope and connect it with ground anchors, and the angle between the wind rope and the ground is not more than 60 degrees. After the overall hoisting and installation of the welding seam of the steel chimney is completed, the inner and outer cylinders of the chimney are fully coated for anti-corrosion. When the paint is applied, the wall surface of the chimney must be treated. Welding slag impurities are removed cleanly, the coating is uniform, the surface of the cylinder is smooth and bright, and the color is bright. The steel plates used in the manufacture of tower chimneys must have steel quality inspection certificates, and all indicators must meet the requirements of Steel Chimney Design documents and relevant current national regulations. The use of substandard steel is prohibited. When the steel arrives at the site, it should be classified and placed. Do not mix different gauges of steel. At the same time, the bottom of idle steel products is flat to avoid artificial accumulation and deformation of steel products, which brings difficulties and unnecessary troubles to construction and production. The above are the advantages of the tower chimney. If you want to know more, please feel free to contact us!
