Fire Extinguishing System

This paper studied the concentration distribution of gas extinguishing agent numerically in high velocity flow field. Civil aircraft power plant compartment has been a difficult area for its high velocity flow field formed after fire happens. Focusing on this issue, certain results, such as mass flow rate of agent gas, total mass of agent and extinguishing efficiency were presented. A typical apparatus of fire extinguishing system was set up, and its fire-fighting efficiency was evaluated. Critical ratio of mass flow rate and flow velocity, gas discharge time and locations of gas sample tubes were recommended. The results and data can provide a practical way in fire extinguishing system evaluation in civil aircraft power plant compartment.

This paper briefly introduces the development of constructing Pumped Storage Power Plant(‘PSP’ for short) and discusses the income form of PSP’s gained subject as well as the existing problems. Meanwhile, the modes of investment management and value compensation and the corresponding differences are also analysed. According to the principle of ‘responsibility for individuals and revenue sharing’, the related mathematical model is developed in this paper, and the ‘quota system’ mode of investment management and value compensation in China is also proposed. The mode is beneficial to the reform of investment and construction system, and can provide fresh energy to the development of construction of PSP in China.

The production capacity of Nuclear Island Mechanical Components (NIMC) falls far behind of massive demand of nuclear power increasement. To achieve the goal of nuclear power development in China, the localization progress of key NIMC needs to be speeded up. Taking material of NIMC (not including nuclear fuel and related material) for example, through the analysis and discussion of the standard or norm, status quo of supply and research, production capacity and existing problems of material of NIMC in China, the major obstacles and factors restricting development of nuclear power plant are found out, and the countermeasures and suggestions are also introduced to accelerate the localization progress of key NIMC in this paper.
