Department of Cooling Water Engineering

The Department of Cooling Water Engineering is engaged in the research and development of the technology concerning the industrial cooling water in thermal and nuclear power plants. Since its establishment, the Department has carried out about 170 experimental investigation of large scale power plants both inside and outside China. Now the Department is developed as the research center in this field in China.

The Department has four laboratories with a total area of 4,200 m². The total staff amounts to 48 including 23 senior engineers, among them 3 possess doctor degree and 12 possess master degree. The research activities are as follows:

1. Optimization of thermal/nuclear power plants and other industrial cooling systems.
2. Investigation of the general layout of cooling water intake/outlet structures and hydro-thermal studies of various waste water receiving bodies.
3. Investigation of fundamental theory of stratified/mixing flow and its applications in engineering projects.
4. Studies on fluid mechanics and thermodynamics of large scale cooling towers.
5. Exploration on water-saving and effective reuse of the latent heat in cooling water.
6. Water environmental assessment and water quality forecasting for thermal and nuclear power plants.

Development and improvement of equipment and instruments for model tests and prototype observations.

The research achievements and experience in water surface cooling engineering, cooling tower engineering and their instrument and equipment obtained by the Department, have been widely adopted and applied in the relevant organizations in China. These research achievements and experience include theory of similarity for cooling water model test and its application to engineering model test; the formation condition and movement equation of thermal plume crossflow and their application to engineering; the model test method for cooling water in tide field; the divergence theory and its engineering layout principle; the model test study on freezing and wind effects; the flow simulation theory and numerical calculation method in large water range; the test and analysis on discharge of waste water and low-grade radioactive materials in nuclear projects; new and high effective fill materials, spout, water receiving equipment and water allocation apparatus used in cooling towers; the calculation method of thermodynamic and obstruction in cooling towers; the muilti-direction flow simulation control system; etc.

To promote the development of economy and to combine science, industry and trade, the Jinghuang Cooling Tower Co. Ltd. has been established jointly by the Department and the Beijing General Institute of Steel Design and Study.

The Qinshan Nuclear Power Station is the first nuclear power station designed and constructed ourselves. Its second and third stage projects are under construction. The total planned install capacity will be up to 3,000 MW. The layouts of intakes and outlets were researched by the Department. The figures show the results of numerical modeling.
