The water resource utilization and water business management situation of thermal power plants in China Huadian Co. Ltd. were described. The water resource developing and utilization, the water saving technique and the improving measures were discussed with comparison of water consumption index of thermal power plants in domestic and abroad. The influences of restriction of construction of thermal power plants by the environment protection policy and the scarcity of water resource were expounded, and some suggestions given in this paper are as following: taking the urban sewage re-using and seawater desalination as the future important water resource, drawing up the strategy of water resource reserve scientifically according to the general distribution of power plant sites and its development of whole group.

The parameters of existing 1000MW Ultra-supercritical units were analyzed combining with the development tendency of the same units domestic and abroad. The recommended parameters for the project of Boxing Power Plant are as follow: 26.25MP and 600℃/600℃ for the ultra-supercritical turbine inlet, 27.56MPa and 605℃/603℃ for the related boiler. The evaporation capacity of boiler usually matches the working condition of VWO (valve widely open) of turbine. By analysis for the parameters of the pipe material, P91, P122 and T91 are selected for the main piping material for this 1000MW unit.

Nitrogen reinjection and syngas wet-saturated are two important methods for the De-NOx of gas turbine in IGCC system. Considering the design of 200MW-class IGCC systems, the two low-NOx combustion methods for IGCC systems were calculated and analyzed. The advantages and disadvantages were discussed from the views of technical index and economic efficiency. Based on this, the rational suggestions were proposed for reference.

An on-line monitoring system for partial discharge of generators was introduced, which was based on the Very High Frequency (VHF) measuring technology and the time-delay identification anti-interference principles. The anti-interference methods applied to this system were analyzed. Considering the application experiences on site and the experimental analysis, the test results and anti-interference capacity were verified. Techno-economic analysis shows that the establishment of such system is conducive to improve the safe operation and the economic benefit for power generation units.

The actual and theoretical power consumption of ESP was calculated and analyzed. The result shows that the operational power consumption of ESP can be classified into effective power consumption, non-effective power consumption and adversely effective power consumption. The pulsed energy-saving and power supply technology was developed to reduce non-effective and adversely effective power consumption greatly, improve power utilization efficiency and realize the energy-saving operation of ESP. This technology was widely verified in many industrial applications.
