Steam generator design requirements The steam generator is commonly known as the boiler. In the pressurized water reactor nuclear power plant, the steam generator is a main equipment in the primary circuit system. It has the characteristics of large size, heavy weight, complicated design and manufacture, and great function. It is called redesign and manufacture. The level of technology for contemporary heat exchangers. For a long time, the steam generator of the international pressurized water reactor nuclear power plant often has corrosion and damage of the heat transfer tube, which has serious problems in reliability. It is the Achilles heel of the nuclear steam supply system, ensuring the quality of the steam generator to improve its safety and reliability. Sex. Due to the complexity of the steam generator manufacturing and the high degree of technical intensiveness, the manufacturing quality is required to meet the requirements of the design specification. Therefore, the design specification is particularly important in the manufacturing process of the steam generator. (1) The design of the steam generator and its components must supply the amount of steam required by the nuclear power plant under any operating conditions and the specified steam parameters. Only by meeting this requirement can the power station be operated economically under any load. (2) The capacity of the steam generator should meet the power load requirements to a greater extent, and the technical and economic indicators are correspondingly improved as the capacity of the single machine increases. (3) All components of the steam generator should be safe and reliable. (4) The assembly of the steam generator with a single zero and components must ensure that the possibility of leakage of the primary circuit fluid into the secondary circuit on the sealing surface is eliminated. (5) Any possibility of exacerbating corrosion must be ruled out, especially in the primary circuit. (6) The steam generator must produce steam of the necessary purity to ensure reliable operation of the steam generator at high temperatures and to ensure reliable and economical operation of the turbine. (7) The steam generator should be designed to be simple and compact, easy to install and use, easy to find faults and promptly eliminated, and may be completely drained. (8) Ensure that the steam generator has high technical and economic indicators. When designing the steam generator, it is necessary to consider the types and parameters of the two working fluids, and correctly select the structural scheme, materials, heat transfer tube size, heat transfer coefficient, and coolant. In addition, measures must be taken to reduce the loss of external heat dissipation.
