High-energy-consuming enterprises set off a technological revolution
Among the manufacturing enterprises, Nanchang Iron and Steel Plant has become a super-powerful household in Nanchang with an average annual consumption of more than 1.6 million tons of standard coal. In order to improve energy efficiency, a year ago, Nanchang Iron and Steel Plant invested 135 million yuan to start a cogeneration project, which collected all the gas produced by burning coke in the steelmaking furnace for power generation and re-use. This alone saves 10% of the electricity consumption and saves 25,000 tons of standard coal.
If the technical transformation of Nanchang Iron and Steel Plant is only to rationalize the production process, then the energy-saving actions of Chenming Paper, which is located in Nanchang Economic and Technological Development Zone, will raise the technological revolution to a higher level through the introduction of high technology. . Mr. Rao Shijing, director of the Environmental Measurement Department of Chenming Paper, told the author that in 2008, the company invested 17.5 million yuan to establish a sludge burning system with a daily processing capacity of 280 tons of sludge. By burning sludge, it partially replaced the use of energy such as coal and electricity. Relying on a series of energy-saving technologies, the company's energy savings this year reached 40,000 tons of standard coal, which is 10% of the annual energy consumption.
It is a general trend to use technology innovation to drive energy efficiency and efficiency. Zhao Wu, the person in charge of the Nanchang Energy Conservation Supervision Center, told the reporter that Nanchang City has launched a series of hard energy-saving measures such as the implementation plan of the unit GDP energy consumption assessment system and the implementation plan of the unit GDP energy consumption monitoring system; In addition to the assessment system of the main officials, it also signed a target responsibility letter of at least 20% energy saving by 2010 with more than 100 enterprises and institutions that consume more than 3,000 tons of standard coal per year.
Public lighting test solar energy
As a vane to demonstrate the government's energy-saving determination, Nanchang's public service system's recent energy-saving actions are unprecedented. On November 25th, the Nanchang City Administration Bureau issued an initiative to recommend that the staff on the first to third floors of the main office buildings, such as the Municipal Party Committee Building and the Municipal Government Building, no longer use elevators.
The more obvious performance is the trial use of solar street lamps and the popularization of technology-based energy-saving street lamps.
When night falls, the 27-inch street lamp near the Cheng Yunxian Sculpture Art Museum in Meihu Scenic Area of ​​Nanchang City is gradually lit. Different from the usual street lamps, these street lamps are powered by solar energy. During the day, the batteries under the lamp holder are charged by sunlight, and the power is automatically turned on at night to light up the bulbs. As an advocate of solar energy application in Jiangxi, Li Weiping, the chairman of Jiangxi Zhaopu New Energy Technology Co., Ltd., has been running around for the promotion of solar street lamps for 1 year. Under his advocacy, more than 500 solar street lights of different shapes entered the parks and scenic spots such as Meihu Scenic Area, Libu Lake Park, Xiaolan Industrial Park, and Anyi Phoenix Mountain Industrial Park, and also opened the public lighting of Nanchang City. The solar era.
The streetlight energy-saving campaign, which has a wider impact, is spread out in the streets. Zhu Haohua, assistant to the director of the street lighting management department of Nanchang City, told reporters that in recent years, Nanchang has gradually promoted high-tech energy-saving lamps such as variable-power sodium lamps, electrodeless lamps and high-efficiency energy-saving garden lamps. The energy-saving rate of new lamps is above 30%; It will also introduce LED energy-saving light sources with more than 80% power saving and 3 times more light efficiency than ordinary lamps.
Home energy saving expectation technology support
In the use of the three major energy sources of coal and electric oil, the family, together with enterprises and public facilities, has become the three major energy-consuming systems. This year, the Nanchang Science and Technology Association held dozens of science and technology publicity activities in the community, and its core theme is energy conservation.
The most effective way to save energy in your home is to use energy-efficient appliances. From August to November this year, Nanchang City has distributed 500,000 household energy-saving lamps to various communities in the city. The relevant person of the Municipal Energy Conservation Supervision Center believes that such a large-scale promotion of energy-saving products initiated by the government is the first time in Nanchang. The direct effect is to save at least 40 million kilowatt hours of electricity per year and save more than 20 million yuan in electricity costs. With the government's advocacy, the citizens' awareness of energy conservation has gradually increased. When interviewing some real estate and home markets in Nanchang, the reporter found that those houses and appliances with energy-saving functions were generally welcomed.
However, an objective reality cannot be ignored. Because the households and household electrical appliances are independent of each other, the use of a single energy-saving electrical appliance is not significant for household energy conservation. To solve this contradiction, in addition to relying on the provision of more energy-saving products by various electrical appliance manufacturers, it is also expected to create an energy-saving monitoring system that can penetrate all household and community electrical appliances, as well as the popularization of solar energy appliances. All of this requires the government to introduce more and deeper scientific and technological support.
