    Description: With the development of society, large capacity and super large capacity thermal power units have gradually become the main force of China’s electric power industry. How to improve the efficiency of power plant units has become increasingly important. Effectively increasing the cooling efficiency of cooling towers can reduce the temperature of cold sources and improve the efficiency of the units. This paper introduces the development of the cooling tower and the internal structure and working principle of the cooling tower. Combined with the existing optimization methods of several cooling towers, the feasible direction of the optimization design of the cooling tower is put forward to provide support for finding the new energy saving technology to enhance the heat and mass transfer of the circulating water and air to further reduce the water temperature of the tower.

    Description: In order to standardize the related procedures and quality control requirements for the construction and quality acceptance of utility tunnel in Shaanxi province. The relevant departments of Shaanxi province have compiled Specification for Construction and Quality Acceptance for Urban Utility Tunnel of Shaanxi Province (The following is referred as Specification). This paper first systematically summarizes the history and present situation of the construction of utility tunnel at home and abroad. Then it is pointed that the main problems in the construction of the utility tunnel in China are the lack of the basis for the construction. Introduced the establishment background, guidelines, framework, for 3 issues were discussed. These 3 problems are that processing and construction method of foundation is still using the housing construction is reasonable or not, whether the configuration of steel bar of top and bottom panels of utility tunnel can be optimized and it is possible fo...
