Develop hydroenergy resources and protect earth environment

Energy is a driving force behind the progress of human civilization. Mainly depend on the current human society of non-renewable fossil energy sources, such as coal and oil, its increasing demand. Gradually reduce the reserves, the contradiction between supply and demand becoming increasingly prominent. With the process of human history has moved forward with the depletion of fossil energy will eventually be unable to sustainable use. The total hydropower resources are limited, but it is renewable, clean energy, its energy is infinite. Therefore, the full use of limited water resources and slow down the depletion of fossil energy process, is to improve and protect the earth’s ecology and environment, one of the most realistic measures.

Characteristics of office lighting energy consumption and its impact on air conditioning energy consumption

The energy consumption of office buildings has increased sharply since the 21st century with the increasing ur-banization coverage.At this stage,the energy consumption of office buildings in China mainly comes from air conditioning and lighting.This paper obtains the regression equation of natural lighting illumination and radi-ant heat gain under different curtain conditions through experiments and simulations,and gives the theoretical calculation process of curtain regulation of office thermal and light environment and energy consumption.DeST and Ecotect software were used to analyze the thermal and light environment and energy consumption of the office.The results show that setting curtains in the room can effectively improve the indoor thermal light en-vironment,the higher the transmittance of curtains the lower the lighting energy consumption,the higher the number of high temperature hours of natural room temperature and the greater the radiant heat gain.The room with thick curtains has the lowest energy consumption for air conditioning in summer,followed by the room with thin curtains,and the room without curtains has the highest energy consumption for air conditioning.The room without curtains has the lowest energy consumption for artificial lighting,the room with thin curtains has the second lowest,and the room with thick curtains has the highest electricity consumption for artificial lighting.The air conditioning energy consumption accounts for the main building energy consumption,followed by the lighting energy consumption.After setting curtains in the office,the air conditioning energy consumption caused by the solar radiation heat entering the room through the exterior windows is smaller than the lighting energy consumption caused by artificial lighting.Therefore,the installation of internal shading with moderate trans-mittance and good thermal insulation performance can make the energy saving of lighting and air conditioning energy consumption reach the optimal value.

Energy Saving for Automatic Train Control in Moving Block Signaling System

With rapid development of the railway traffic, the moving block signaling system （MBS） method has become more and more important for increasing the track capacity by allowing trains to run in a shorter time-headway while maintaining the required safety margins. In this framework, the tracking target point of the following train is moving forward with its leading train. This paper focuses on the energy saving tracking control of two successive trains in MBS. Nonlinear programming method is used to optimize the energy-saving speed trajectory of the following train. The real-time location of the leading train could be integrated into the optimization process. Due to simplicity, it can be used for online implementation. The feasibility and effectiveness are verified through simulation. The results show that the new method is efficient on energy saving even when disturbances present.

RAW MEALS CONTAINING TRACE RE OXIDES TO IMPROVE QUALITY OF CEMENT CLINKER

Clay or industrial wastes containing trace rare earth (RE) oxides as one of the components are used to burn cement clinker. When the total amount of RE oxides reaches 0. 2×10-4 - 2. 0×10-4 (wt), it has positive effect on the burnability of raw meals? and the Alite content in clinker increases. However, with the addition of lan-thanide, the formation process of clinker and the distribu-tion of lanthanide in clinker are different from those of yt-trium. If the burning temperature is 1 450 C , yttrium shiws negative effect on the formation of clinker. There-fore, to improve the quality of cement clinkern, the raw meals in which yttrium content is lower and lanthanide con-tent is higher is preferable; to reduce the consumption of coal, the raw meals that yttrium content is higher is suit-able. Using raw meals containing trace RE oxides can re-duce the cost of fluorite and protect environment.
