At that time, it was the first large all steel structure intercooling tower in China
. 
The all steel structure intercooling tower of Huaneng Ningxia Daba Power Plant Phase IV project is composed of four parts: “cylinder + cone + reinforcing ring + widening platform”
. 
Compared with the traditional concrete structure intercooling tower, steel structure intercooling tower has many advantages, such as low cost, good seismic performance, short construction period, outstanding environmental protection, less overhead workers and so on
. 
Recently, the new construction project of Guodian Shuangwei power plant, which is contracted by Guodian Longyuan Power Technology Engineering Co., Ltd., has another good news: the steel structure indirect air cooling tower of unit 1 has been successfully topped
. 
As a typical example of innovative engineering, resource-saving engineering, circular economy demonstration engineering and intelligent construction engineering, intelligent all steel structure indirect air cooling system technology has good seismic resistance, low construction investment, short construction period and more convenient construction Shuangliang will continue to develop the market, based on the existing achievements, continue to innovate and optimize, forge ahead, and strive to contribute to “carbon neutralization”
. 
The surface of the steel structure is protected by cold spraying zinc
. 
The traditional concrete tower has low residual value rate, long construction period and high risk, which is not in line with the requirements of the era of green environmental protection and low-carbon development
. 
The height of the tower is 169 meters, the diameter of the cylinder is 82 meters, and the diameter of the cone bottom is 129 meters
. 
on April 13, 2018, China’s first large steel structure intercooling tower was successfully capped at the site of phase IV 2x660mw project of Huaneng Ningxia Daba Power Plant

.
It is composed of “cone + widening platform + cylinder + stiffening ring”
.
At the same time, the steel structure intercooling tower has many difficulties, such as large volume, high height, difficult welding, high precision requirements, complex spatial positioning when installed in place, and need to connect steel truss units by welding node ball
.
Its power generation capacity, volume, diameter and height of single tower were the highest in the world
.
Attachment: at 10:28 a.m
.
After the service, all steel and aluminum materials of the steel tower can be recycled without any construction waste, which fully responds to the national environmental protection industrial policy of promoting environmental protection energy development
.
The short video “steel intercooling tower” broadcast by Ningxia satellite TV “brand Ningxia” reproduces the construction process of two all steel structure intercooling towers in Huaneng Ningxia Daba Power Plant Phase IV
.
It is the highest steel structure intercooling tower under construction in the world

The cone has 6 layers, the height is about 65m, and the diameter at the bottom is about 148.7m; the widening platform has 2 layers, and the truss structure is adopted; the upper cylindrical tower has 12 layers, the height is about 125.2m, the outlet diameter of the steel tower is 92.5m, the tower height is 190.2m, and the diameter of the steel structure axis at the bottom is 148.7m The main structure of the tower is a space structure composed of 704 lattice triangles
.
The steel structure indirect air cooling tower body of unit 1 is full steel structure, q355b steel is used, and the tower weight is about 6500 tons
