"Twelve Five" mechanical industry preliminary determination of energy-saving emission reduction targets

As a strategic pillar industry of China, the machinery industry shoulders the heavy responsibility of providing equipment for various industries and national defense construction of the national economy. The advanced, efficient, energy-saving, and environmental protection products it produces have a direct impact on the economic efficiency, energy consumption, and pollution of the equipment industry. The emission of materials is the source and guarantee of energy conservation and emission reduction targets for various industries. This is the statement made by Wang Ruixiang, president of the China Federation of Machinery Industry, on the 18th of the first “Conference on Energy Saving, Emission Reduction, and Utilization of Resources in the China Machinery Industry”.

The urgent data of energy-saving and emission-reducing in the machinery industry show that: "Eleventh Five-Year Plan" China's machinery industry has obvious energy-saving and emission-reducing effects, and the comprehensive energy consumption per 10,000 yuan of industrial added value has decreased year by year In 2006, it was 0.56 tons of standard coal, in 2007 it was 0.46 tons of standard coal, in 2008 it was 0.45 tons of standard coal, and in 2009 it was 0.42 tons of standard coal.

Throughout the “11th Five-Year Plan” period, not only the expected goals have been achieved, but also a large number of energy-saving and emission-reduction products that meet the requirements of the country and are even close to the international advanced level. Taking thermal power generation equipment as an example, in 2009, the ratio of supercritical and ultra-supercritical generating units with a production capacity of 300,000 kilowatts or more was 67%. The coal consumption per kilowatt of ultra-supercritical thermal power units is more than 16% lower than the current domestic average.

The reporter learned from the interview that although China's machinery industry has made great achievements in energy conservation and emission reduction, the current situation of the machinery industry and the urgent situation of energy conservation and emission reduction are not suitable. The first is that some hot-processing processes that are suitable for the use of advanced technology and equipment to achieve centralized and large-scale production are highly fragmented and duplicative. Many small-scale production sites have low levels of management and cannot adopt advanced technologies, but they also occupy the market and affect the advantages of advanced enterprises. Secondly, the overall level of mechanical products is relatively low, and there is still a significant gap between most products and the international advanced level. The efficiency of most products is lower than the international advanced level. Taking a diesel engine as an example, the fuel consumption is 5% to 15% higher than the international advanced level, and the overall emission level is 1-2 levels lower than the international advanced level. Third, the thermal processing technology in the machining process is obviously lagging behind. In particular, the thermal processing technology of a large number of small and medium-sized enterprises is lagging behind. As a result, the energy consumption of thermal processing in the entire industry is significantly higher than that of the international industrial countries. Taking forging process energy consumption as an example, China is generally 0.55-0.7 tons of standard coal / ton castings, the international advanced level is 0.3-0.4 tons of standard coal / ton castings, China's energy consumption per ton casting casting process is about 80 higher than the international advanced level. %. Finally, the utilization rate of materials in China's machinery industry is low. Taking the material utilization rate of bearing rings as an example, the gap is not small: China's backward companies are 30%-40%, general enterprises are 50%, advanced enterprises are 70%, and international advanced level is 75%.

The above-mentioned reality requires that the practice of industrial upgrading of the mechanical industry urgently needs to shift to the direction of energy conservation and emission reduction, technical support, and industrial innovation. Cai Weici, executive vice president of the China Federation of Machinery Industry, said: "In the future, the machinery industry needs to accelerate the upgrading of the industrial structure of the machinery industry through the formulation of energy-saving technical standards and the promotion of energy-saving technologies and emission reductions; and the use of advanced energy-saving technologies and equipment to enhance product design and manufacturing. The use of energy in the sector to promote the industrial restructuring in an all-round way.”

The energy consumption of the machinery industry fell to 0.31 tons of standard coal Cai Weici revealed at the meeting that the “12th Five-Year Plan” energy-saving emission reduction target for machinery industry has been initially determined, and the comprehensive energy consumption of the industrial added value of the machinery industry was reduced by 0.42 tons of standard coal in 2009. By 2015, 0.31 tons of standard coal had declined by 4.9% annually. Among them, the energy consumption per million yuan in casting was reduced by 0.496 tons of standard coal; the energy consumption per ton of qualified castings was reduced by 0.1044 tons of standard coal; the exhaust emissions such as carbon dioxide were reduced by 12 billion cubic meters. The energy consumption of heat treatment unit products was reduced by 150 kWh/ton; energy consumption per million yuan was reduced by 200 kWh/million. The internal combustion engine strives to reduce fuel consumption by 10% and its emissions are synchronized with international standards. The operating efficiency of coal-fired industrial boilers has been increased to over 85%; the operating efficiency of industrial furnaces has been increased by 5% on an existing basis; the design energy efficiency index of small and medium-sized motors has reached 95%. The design energy efficiency index of the fan reaches 92%-95%.

Cai Weici also said that the "12th Five-Year Plan" machinery industry will face some new situations. First, we must meet the requirements of a conservation-oriented and resource-friendly society. Second, we must meet the requirements of the global trend of green development. Product efficiency levels and environmental protection indicators must be fully implemented in all aspects of the industrial chain from design, manufacturing to after-sales service. The concept of “green”; the third is to realize the development of the industry under the constraints of resources and the environment; and finally, the status quo of the machinery industry has a clear gap with the above requirements.

Many parties appealed for more subsidies. During the interview, what the reporter heard most was the industry’s call for policies to increase subsidies for energy-saving technologies in the machinery industry.

Cai Weici suggested that in order to ensure that industries that focus on promoting energy conservation and emission reduction can obtain support from advanced and high-efficiency equipment, relevant departments should regard such equipment as a key to encourage development. Actively support the mechanical enterprises to carry out technological transformation oriented to energy conservation and emission reduction, and provide support for planning and funding subsidies for major projects with typical significance. The key industries such as foundry, forging, heat treatment and other thermal processing industries in the machinery industry, electrical machinery, transformers, and internal combustion engines should be included in the national “Twelfth Five-Year Plan” energy-saving and emission reduction planning key work plan, and policies and funds should be provided. stand by.

Xu Zhishan, a senior engineer at the Technical Center of China Central Tianyi Co., Ltd., told this reporter that the machinery industry is much more advocacy for energy-saving and emission-reduction, and the actual application is in place. He appealed that relevant departments should organize more expert forums and reviews, and give more financial support to enterprises with invented and technological machinery enterprises.

Zhou Shoulian, technical director of Beijing Bijie Electric Co., Ltd., told reporters that each KW subsidizes 5 yuan on the basis of high-efficiency motors is far from enough, and the subsidies for ultra-efficient motors are very small, which is not conducive to the leading role of industry-leading companies. I hope the country will adjust it. Every motor that needs to be subsidized must have traceability, and whoever buys it or uses it should be clear at a glance. This is also a difficult business. It is hoped that relevant departments, in addition to certifying mechanical energy-saving products, also need to actively promote the combination of mechanical energy-saving products with the national policy of benefiting the people.

For Zhou Shoulian’s proposal to call for the combination of mechanical energy-saving products and Huimin policies, Xie Ji, Director of the Department of Resource Conservation and Environmental Protection of the National Development and Reform Commission, agrees: “Only the application of high-efficiency motors can be greatly improved.” The conference proposed that it is hoped that the machinery industry enterprises will strengthen the research and application of low-carbon technologies, because many international products require a carbon footprint. As a product equipment manufacturer, it is necessary to consider displaying the carbon footprint on products in advance, because foreign supermarkets require that products be manufactured. The carbon content produced during the process.
