Since foundry industry is one of the major source of energy consumption and pollution emission (especially CO 2 ), issues concerning energy-saving and emission-reduction have been raised by governments and the industry. Specialists from around the world carried out multidimensional analyses and evaluation on the potentials in energy conservation and emissions reduction in iron and steel industry, and proposed various kinds of analyzing models. The primary measures mainly focus on the targeted policies formulation and also on clean and highefficient technologies development. The differences and similarities in energy conservation and emission reduction in foundry industry between China and other countries were discussed, while, the future development trend was also pointed out.展开更多

The use of energy conservation emission reduction policies to promote industrial restructuring and upgrading and thus facilitate energy conservation and emission reduction is one of the important strategies of environmental management in China. Based on the systematic collection of 1,195 energy conservation emission reduction policies, we discuss the influence of individual measure and measure synergy of energy conservation and emission reduction policies respectively. The results show that the energy conservation and emission reduction policies have a significant effect on the overall promotion of industrial upgrading. The financial measures and guidance measures have a positive impact;the financial measures and guidance measures have significantly positive effect; however, the administrative measures, fiscal tax measures, and other economic measures do the opposite; the positive effect of the synergy of guidance measures and financial measures is greater than the negative effect of considering only the synergy of fiscal tax measures and other economic measures, and significantly greater than the negative effect of the synergy of administrative measures, fiscal tax measures, and other economic measures. We should strengthen and emphasize the use of the measure that has positive effect on industrial structure restructuring and upgrading individually and synergistically.展开更多

The energy consumption per unit GDP in the ICT industry is lower than that in other industries. The application of ICT in such fi elds as industrial design, manufacturing, management, logistics, sales and service can be helpful for energy conservation and emission reduction in the industrial and transportations industry; however, the issue of energy waste and environmental pollution caused by voluminous deployment of ICT products should never be overlooked. This paper presents the lat- est development of communications products in energy conservation and exemplifi es the roles of ICT in energy conservation and consumption reduction. The issue of electromagnetic radiation of ICT products and the recycling and reuse of e-wastes are explored.展开更多

Breeding cycle is one of the main patterns of ecological animal husbandry development, but breeding cycle does not form a relatively closed cycle of endogenous resources. In recent years, forage value and ecological value of mulberry have made some progresses in different research areas and angles, but the thought and practice of both forage and ecological value of mulberry has not been systematically interpreted and researched. Based on the short board of animal husbandry development and the advan- tage of mulberry, animal husbandry and mulberry were complemented and fused, and relatively closed planting and raising ecological recycling pattern with mulberry as the axis was raised. Phased scientific research and production test data were obtained, and the problems and development suggestions were put forward in the following aspects : selection of mulberry varieties with both forage and ecological value, cost control of mulberry with both forage and ecological value, quality and safety control system of forage mulberry, orientation of feeding value of forage mulberry.展开更多

Utilization of Coal-Water Slurry (CWS) can improve the burning efficiency of coal and reduce the pollutions of soot, sulfide and the nitride by burning lump coal directly. The CWS is a promising energy saving technique and the effectual substitute of oil. The study on the preparation and application of the CWS has made progresses in many aspects. The present paper studied the basal problems for applying the CWS on the rotary kilns during the calcining-dolomite process in the magnesium factory, summarized the key points for the application process of the CWS and gave the corresponding solutions.展开更多

The wind power’s grid integration status quo is introduced, and the bottle neck of grid integration is analyzed. By the study on the economic benefits of wind power integration in China’s present stage, the results indicate that the wind power industry is in good condition of profits and the profits are higher with the increase of the wind resources in the areas. Through expanding the difference of the power purchase prices in different resource areas, it is beneficial for the nationwide harmonious development of wind power. At last, the present and future benefits of the energy conservation and emission reduction from wind power integration are estimated, which shows that the environmental benefits of "wind-thermal exchange" will be more and more outstanding along with the expansion of the scale of wind power.展开更多

Improving the system efficiency of the electric submersible pump wells, ensuring that the units operate in the high-efficiency zone, is essential. Analysis shows that the efficiency of the electric submersible pump system depends on the wear and tear of each component of the submersible pump equipment, the setting of operational parameters, and more importantly, the production status and daily management level of the oil well. Therefore, improving the structural performance of the submersible pump product, optimizing the parameters setting of the oil well, strengthening daily management, establishing a scientific management system, and improving the production management process and system can effectively improve the production efficiency and economic benefits of the oil well, and further achieve the goal of energy saving and emission reduction. In addition, it is necessary to actively promote the concept and technology of energy saving and emission reduction, encourage oilfield enterprises to explore effective measures to reduce the energy consumption of the electric submersible pump system by strengthening the scientific management system, and achieve a green, low-carbon, and high-quality development of oilfield production to achieve the unity of economic benefits, social benefits, and environmental benefits. This article applies the above measures in the P oilfield to achieve energy optimization of submersible electric pump systems, reducing the daily power consumption of single well submersible electric pump systems by 371 kWh per day, increasing the submersible electric pump's lifespan by 200 days, generating considerable project benefits.展开更多
