Thermal engineering analysis and heat transfer performance of duct-type steam generator in nuclear power plant
摘要
Abstract
To improve steam parameters for better power generation efficiency and economy and meet the development needs of nuclear power plants,a duct-type steam generator is proposed,which is suitable for high-temperature gas-cooled reactors with ultra-supercritical parameters.The main features of the duct-type steam generator's structure are introduced,and the advantages of this structure in terms of heat transfer performance,operation safety,and production cost are analyzed.Through the establishment of a theoretical calculation model,thermal engineering analysis and heat transfer performance study of axial,radial,and quasi-three-dimensional temperature distributions and other parameters of the steam generator with direct countercurrent heat transfer mode are carried out.The calculation results show that,the duct-type steam generator is mainly based on convection heat transfer mode,with obvious temperature distribution segments and excellent heat transfer performance,which meets the relevant heat transfer requirements.This study can provide a reference for design and development of steam generators in nuclear power plants.关键词
