Cooling Tower of Ningmei Project

With the development of national economic construction, industrial water consumption has increased sharply. Promoting cooling towers and achieving the circular use of industrial and refrigeration water has significant practical significance for saving water, protecting the environment, and reducing energy consumption. Therefore, the demand for cooling towers in China has been increasing year by year. Cooling towers are large heat exchangers that mainly supply cooling water to power plants and manufacturing plants; This water sequentially cools the equipment necessary for daily operations.

Because the structural materials used in the operation of cooling towers must withstand various environments, including chemical and biological invasion as well as harsh conditions, the pultruded fiberglass (GFRP) profile, in addition to its high strength, light weight, and strong corrosion resistance, is highly economical and has the most stable material properties compared to other fiberglass production processes such as hand lay up or RTM. Therefore, it is an advantageous choice for cooling tower structural components.

The use of GFRP extruded into shape as a structural material for cooling towers has significant advantages compared to wood, concrete, and steel

●Compared with wood, there is no biomass corrosion, and glass fiber and resin do not provide microorganisms;

●Compared with steel and concrete materials, GFRP has good chemical corrosion resistance;

●Compared to structural materials such as wood, steel, and concrete, it is lighter in weight;

●Maintenance free, easy to ｒｅｐｌａｃｅ even damaged parts;

In 2015, the cooling tower of the Ningmei project began using FRP extruded materials as the main supporting structure. The coal indirect liquefaction project of Shenhua Ning Coal Group is the only large-scale coal to oil demonstration project in China, and is listed as the "No.1 Project" by Ningxia Autonomous Region. The project is located in the Energy and Chemical Industry Base of Ningdong Town, Lingwu City, Ningxia, China, with a total investment of 55 billion yuan and a designed annual production of 4 million tons of oil products. The cooling towers for the first and second circulating water plants of the 4 million tons/year coal indirect liquefaction project's water system engineering are fiberglass towers (constructed with extruded FRP profiles, provided by Speer). Design 60 cooling towers, each using approximately 45 tons of FRP extruded profiles.
