World power

In the East China Sea, Yuhuan County, Zhejiang Province Damaiyu beach, the two more than 90 meters high the great Steel buildings are going up, a 10-ton terminal is like a dragon probe into the East China Sea, which is the construction of our country’s first Domestic Equipment million kilowatt-class ultra-supercritical coal-fired power plant unit - Zhejiang Huaneng Yuhuan Power Plant. The installed capacity of power plant plan 4 sets of 1 million kilowatts of ultra-supercritical coal-fired units, a construction of two 100-million KW, was started in June 2004 is expected to put into production by the end of 2007. Electricity experts point out that the national key project of energy saving, environmental protection, water-saving advanced technology represents the development direction of China’s coal-fired power plant for the realization of the sustainable development of electricity as a pioneer.

≠ coal power generation multi-multi-

This is a layman to read I do not know why the professional terminology - ultra-supercritical coal technology. Electricity experts say the most simple and illustrates the superiority of the technology: the average power of China’s coal consumption in 2004 compared to application of such coal-fired power generation technologies can be made a unit of electricity is about 88 grams economizer; assembly in accordance with China’s current coal-fired power machine capacity, if the coal-fired power plants nationwide have adopted the technology generation, annual savings of more than 200 million tons of coal.

high energy consumption, unit coal-fired generating capacity is far behind the international advanced level, is China’s coal-fired power the outstanding problems. Power shortage is behind the coal shortage. According to statistics, China’s coal supply in 2004 was about 1.98 billion tons, while the actual demand is about 2.1 billion tons, of which only the demand for coal over the previous year an increase of 1.2 million tons.

Shiliu Tai made in accordance with the party’s 2020 gross domestic product quadrupled the requirements of the next 15 years, China will add 300 million kilowatts thermal power units or more, which requires the coal supply will be large increased by this amount. Thus, as a non-renewable energy sources, severely limit the supply of coal to coal-fired power plant-based sustainable development of China’s power industry, the construction of a number of highly efficient type of power plant economizer imminent.

Huaneng Yuhuan Power Plant charge of the projects under construction in 1,2 Li Jianmin pointed Units told reporters, according to an annual generation capacity 5500 hours terms, all four units a full year after completion of the power plants generating 22 billion degrees. With the current widespread use of sub-critical coal-fired power plant units of comparison, Huaneng Yuhuan Power Plant, the same amount of power to issue an annual savings of 400,000 tons of coal to truly realize the power does not mean more coal and more energy-saving goals.

Lu Yanchang, chairman of the Chinese Society of Electrical Engineering at the interview with Xinhua, said: “At present, China’s coal power generation accounted for more than half of domestic coal production, coal and the scarcity of resources has become a key constraining factor in the development of coal-fired power plants. Huaneng Yuhuan Power Plant first to use the international advanced ultra-supercritical coal-fired units, on behalf of the Chinese coal-fired power plants in the future development direction for the coal-fired power plant economizer has played an exemplary role.

generating more pollution, more than _ ≠ xxx_1_br>
2004 years, statistics show that ash produced by coal-fired power generation accounting for about 70% of ash, smoke and dust emission accounts for 33% of industrial emissions of sulfur dioxide emissions from industrial emissions accounted for 56%. Lu Yanchang that a large quantity of pollutant discharge the existence of China’s coal-fired power generation is another outstanding problems.

the face of a huge power plant 240-meter high chimney, in charge of works seem to see a reporter who Jianmin concerns, he smiled and said: “We are generating more, but never on behalf of pollution abound. “

It is reported that Huaneng Yuhuan Power Plant, the use of ultra-supercritical coal-fired units, coal power generation capacity to be reduced, the resulting pollutants are reduced. Meanwhile, the plant invested heavily in environmental protection, to air pollution, water pollution, solid waste pollution and noise pollution prevention and control measures are tight.

State Environmental Protection Administration of Environmental Engineering Assessment Center under the auspices of assessment would think that Huaneng Yuhuan Ultra-supercritical power plants belonging to one million kilowatts of clean coal technology, is the world’s most advanced coal-fired power generation technology. Power Plant After treatment, sulfur dioxide, nitrogen oxides and soot emission concentration limits are far below the national regulations, other indicators of pollution control are in line with the national standard, wastewater recycling even reached 100%. Therefore, the project construction on the stability of the local atmospheric environment conditions and to enhance China’s overall level of electricity production have an active role.

Lu Yanchang told reporters in the country to use ultra-supercritical coal-fired power plants to improve the proportion of units is to reduce the pollution, the most effective and realistic way, which is both long-term plan is even more imperative. Huaneng Power Plant in the building of environment-friendly aspects of the Dai Lege other domestic plants a good start.

≠ water for power generation multi-fuel multi-

coal-fired electricity require large amounts of circulating cooling water, industrial cooling water, and chemical make-up water, for use of seawater DC cooling technology units, the water consumption per one million kilowatts is necessary to 0.12 tons per second of fresh water. At present, China’s per capita water resources is only 2,200 tons, about 31% of the world’s average, is the world’s 13 most water-poor individuals to one of the countries.

Huaneng Yuhuan Power Plant annual production needs of 8 million tons of fresh water, while the Yuhuan County in Zhejiang Province as a focus on water shortages in drought-prone island county, the county seven full capacity of the reservoir water storage capacity also less than 20 million tons of water has begun to affect the county’s sleepy sustainable development of 8 million tons of fresh water is a tremendous burden.

no fresh water on to the sea to fresh water. Huaneng Yuhuan Power Plant, opened up China’s “double-film” method desalination process precedent, investment 200 million yuan to build a system of water per hour to reach 1440 tons of sea water desalination systems to power all from the desalination plant water requirements.

the same time, Huaneng Yuhuan Power Plant, the whole plant process water quality classification points has been optimized, so that fresh water recycle rate of 64% or more, up to 100% recycled waste water , significantly reduced the consumption of fresh water resources. gigawatt power plant water consumption per unit volume of nearly 0.09 tons per second, close to 0.08 tons per second, the international advanced level.

Lu Yanchang pointed out that China’s water resources are relatively sleepy requested that “conservation water, reduce water consumption “as the study of coal-fired power generation technology, an important issue. In the efforts to improve the utilization of fresh water to repeat the same time, coastal areas with sea-water desalination technology, inland area studies approach to mine water treatment. construction of water-power plants, right an increasing scarcity of water resources in China is of great significance.

Xingmei, environment protection, water conservation, so that the completion of Huaneng Yuhuan Power Plant will become the thermal efficiency of coal-fired generating units, integrated energy-saving and environmental protection, one of the highest levels of coal-fired power plants , reached the international advanced level. This is not only achieved a qualitative leap in China’s thermal power generation technology, but also to China’s power industry to the strategic objectives of sustainable development has taken a solid step forward.

华能玉环电厂：三个不平等宣布可持续发展的动力

在东中国海，玉环县大麦屿浙江省海滩，两位90多米高的大钢建筑正在兴建中，10吨码头就像是下城东中国海，这是建设龙探针我国第一个国产设备百万千瓦级超超临界燃煤电厂机组-浙江华能玉环电厂。该电厂计划的4 100万万千瓦超临界燃煤机组，有两个100建造万千瓦，集于2004年6月开始装机，预计投产，到2007年底。电力专家指出，国家节能，环保，节水先进技术，重点项目代表了中国煤炭发展方向发射了电力在社会的可持续发展是实现先锋电厂。

≠煤发电多多

这是一个门外汉，读，我不知道为什么专业术语-超超临界燃煤技术。电力专家说，最简单，并说明该技术的优势：对中国的煤炭消费量在2004年的平均功耗相比，应用这种煤发电技术，可单位的电力大约是88克省煤器;大会根据与中国目前的燃煤发电设备容量，如果燃煤电厂全国已采用该技术的一代，超过200万吨煤炭每年节省。

能耗高，单位燃煤发电是远远落后于国际先进水平的能力，是中国的燃煤发电厂的突出问题。电力短缺的背后是煤炭短缺。据统计，中国2004年的煤炭供应约198亿吨，而实际需求量约2.1亿吨，其中只有上年的需求煤炭120万吨增加。

时浏大提出按照党的2020年国内生产总值翻了两番未来15年的要求，中国将增加三万点〇万千瓦火电机组或更多，这需要煤炭供应量将大量增加这一数额。因此，作为不可再生能源，严重限制了煤炭供应的煤发电厂为基础的中国电力工业的可持续发展，一个高效率的发电厂建设一批省煤器类型迫在眉睫。

华能玉环电厂负责的在建项目在1,2李建民指出单位告诉记者，根据1年发电量五千五百小时方面，一周年后的220亿美元的发电设备完成度，所有四个单位。由于目前广泛使用的亚临界燃煤电厂的单位比较，华能玉环电厂，同样的功率发出40万吨煤，每年节省真正实现的权力，并不意味着更多的煤多节能目标。

陆延昌，对电机工程学会会长在接受新华社记者采访时说：“目前，中国的煤炭发电超过国内煤炭生产，煤炭资源紧缺的一半已成为一个关键的制约煤炭发展的因素发电厂。华能玉环电厂率先使用对我国煤炭代表国际先进的超临界燃煤机组，锅炉在为未来的发展方向煤炭发电厂发电植物省煤器发挥了模范作用。

产生的污染多，_≠xxx_1_br>
2004年的统计资料显示，煤炭所产生的灰烬发电约70火山灰，烟雾和粉尘排放占％，发电占33％对来自工业排放的二氧化硫排放占工业排放量的56％。陆延昌的是，污染物排放大量的中国煤炭存在发电是另一个突出问题。

庞大的电厂面对240米高烟囱，工程负责似乎看到谁建民记者的关注，他微笑着说：“我们正在创造更多，但从未代表污染比比皆是。 “

据悉，华能玉环电厂，使用超临界燃煤机组，燃煤发电量会有所减少，由此产生的污染物被削减。与此同时，工厂投入巨资保护环境，对空气污染，水污染，固体废物污染和噪声污染的预防和控制措施，严密。

根据评估的主持下，国家环保总局环境工程评估中心会认为，华能玉环超超临界电厂属于百点○万千瓦清洁煤炭技术，是世界上最先进的燃煤发电技术。电厂治疗后，二氧化硫，氮氧化物和烟尘排放量远远低于国家规定的浓度限制，污染控制的其他指标均符合国家标准，废水回收甚至达到100％。因此，对当地的大气环境状况稳定工程建设，并加强中国对电力生产的整体水平具有积极的作用。

陆延昌告诉记者，在该国使用超临界燃煤发电厂，以提高单位的比例是为了减少污染，最有效和现实的方式，这既是长远大计，更要在环境建设。华能电厂，对戴勒热有利的方面国内其他植物一个良好的开端。

≠发电多燃料多水

燃煤发电需要循环冷却水，工业冷却水大量，化学化妆水，用海水直流冷却技术单位，每1000000千瓦用水量要每秒0.12淡水。目前，中国人均水资源仅为2200吨，约31世界平均水平的％万吨，是世界上13个最缺水的对个人的国家之一。

华能玉环电厂全年生产需要800万吨的淡水，而在浙江省玉环县作为一个缺水易旱岛县的重点，全县7个全能力水库蓄水量也不足20吨的水，已开始影响到县的沉睡了800万吨淡水的可持续发展是一个巨大的负担。

没有淡水到海水的淡水。华能玉环电厂植物，开辟了中国的“双膜”法海水淡化工艺的先例，投资2亿元建设一个水系统每小时达到1440海水淡化系统吨权力来自海水淡化厂的水全部要求。

相同当时，华能玉环电厂，全厂工艺用水的质量分类站进行了优化，使新鲜用水重复利用率为64％或更多，达100％回收废水，大大减少了淡水资源的消耗。瓦的电力工厂每单位耗水量近0.09吨每秒，接近0.08吨每秒，国际先进水平。

陆延昌指出，中国的水资源相对困乏要求“节约用水，减少耗水量的”量研究燃煤发电技术，一个重要的问题。在努力提高淡水重复利用率的同时，沿海地区的海水脱盐技术，内陆地区研究矿井水的办法处理。水利建设电厂，权利在中国的水资源日益匮乏，是十分重要的意义。

性美，环保，水利，使华能玉环电厂建成将成为煤热效率燃煤发电机组，集成节能环保，煤炭最高水平的发电厂，达到国际先进水平。这不仅实现了中国的热发电技术质的飞跃，而且中国的电力工业的战略目标可持续发展迈出了坚实的一步。06.9.25
