New development of power environmental protection

The continuous implementation of the policy of strengthening power supply for more than a decade has enabled China's power industry to develop rapidly. After entering the year 2000, the total installed power capacity has exceeded 300 million kilowatts. From the current situation, the growth rate of new power supply can basically achieve a dynamic balance with the higher growth rate of the national economy.

At the same time, the power supply structures that rely more on thermal power generation have not yet been effectively improved. At present, coal-fired power generation still accounts for over 75% of the total power consumption. The environmental pollution caused by it has also become more serious. In 1998 and 1999, the total amount of sulfur dioxide emitted by coal combustion in China reached 20.87 million tons and 18.57 million tons, ranking the first in the world, while the northern region successively The occurrence of large-scale dust pollution and acid rain, thermal power plants have become one of the major air pollution sources in China. In addition to sulfur dioxide, a certain amount of sewage is also formed in the thermal power production process, which constitutes a part of power pollution.

Power pollution has long attracted the attention of the relevant government departments. The State Environmental Protection Administration and the State Economic and Trade Commission have successively promulgated administrative regulations such as the “Emission Standards for Air Pollutants for Thermal Power Plants” and “Key Technologies for Localization of Flue Gas Desulfurization in Thermal Power Plants”. And adopt policy regulations and economic leverage to promote thermal power companies to implement environmental protection measures, in order to achieve the power industry to environmental protection development policy objectives.

Environmental protection of the power industry: There are mainly two ways to mitigate or solve thermal power pollution in two emerging industries. One is to implement environmental protection measures in the thermal power production, including flue gas desulphurization and power plant water treatment; the second is to improve the power supply structure, to the thermal power plant. It is of direct significance to develop waste-to-energy. As a result, two new fringe industries have emerged in the cross section of the thermal power industry and the environmental protection industry, namely, the power environmental protection industry and the environmental protection power industry, which together constitute the main content of the environmental protection of the power industry.

Power environmental protection is mainly through the installation of environmental protection devices in thermal power plants to control the emission of sulfur dioxide and sewage. The current control focuses on sulfur dioxide. According to the different control processes, sulfur dioxide treatment can be divided into three categories: pre-combustion, combustion and post-combustion. At present, domestic use mainly includes post-combustion desulfurization, ie, flue gas desulfurization, desulfurization equipment and certain stand-alone installed capacity. The power station boilers are matched. The internationally mature flue gas desulfurization technologies include five kinds of limestone-gypsum method, sea water desulfurization method, spray drying method, calcium spray humidification method, and electron beam method. They are ABB of Sweden, Mitsubishi Heavy Industries of Japan, Hitachi of Japan, and WULL of Germany respectively. It is controlled by European and Japanese companies. Compared with the above-mentioned companies, China still does not have complete design and equipment capacity for large-scale unit flue gas desulfurization of 200,000 kilowatts or more. Domestic flue gas desulphurization projects implemented by thermal power plants need to import equipment from abroad, and civil engineering and installation are Completed domestically. The power plant water treatment mainly includes condensate water project, boiler water supply project, ash flushing water and water return project, boiler cleaning, ash transport pipeline cleaning and other cleaning, mainly through polymer coagulants and scale inhibitors and other chemical agents. To achieve the treatment of coal-fired power plant water pollution and solve the serious fouling problem of coal-fired power plant ash-cleaning pipelines, the degree of water pollution of power plants is relatively light compared with the sulfur pollution in coal-fired power plants, but the absolute pollution is still relatively large and needs to be obtained. With effective treatment, some domestic enterprises have already mastered this technology.

Environmental power is a newly emerging fringe industry and is currently concentrated in the waste-to-energy sector. It uses municipal waste and coal gangue as an alternative fuel for coal. While producing clean energy, it can also effectively reduce urban waste pollution. At present, there is a garbage power plant in Shenzhen and Zhuhai in China that has entered operation.

Environmental Protection of the Power Industry: Industrial Opportunity Highlights The power environmental protection industry and the environmental protection power industry derived from the environmental protection trend of the power industry are expected to develop at a faster rate than the power industry itself, which is mainly based on the large potential market size and strong Policy support.

In the power environmental protection industry, flue gas desulfurization is a priority area for high-tech environmental protection. In order to realize the localization of related technologies and equipment, the State Economic and Trade Commission has recently announced the "national key planning for flue gas desulfurization technology and equipment in thermal power plants. According to the above, the National Power System plans to invest 10 billion yuan in the research and development of wet flue gas desulphurization-related technologies and equipment, with a view to bringing the localization rate of wet flue gas desulfurization equipment to 100% by 2010. According to China's "Atmospheric Environmental Protection Law" and "Air Thermal Emission Standard for Thermal Power Plants," and other requirements, by 2010 China needs to install flue gas desulphurization unit of about 180 thermal power generating units, with an installed capacity of 44 million kilowatts. If the investment for installation of desulfurization equipment accounts for about 10% of the total investment of the power plant, the total investment for a wet desulfurization plant for a 1 million-kilowatt unit is estimated to be approximately 7.5 billion yuan. According to this, the flue gas desulphurization market in China's power plants will be 10 years in 2010. The scale is expected to reach more than RMB 330 billion. In China, currently only less than 1% of the installed capacity of thermal power plants have flue gas desulphurization devices, which are imported products from abroad. It can be seen that the huge potential market demand for flue gas desulfurization equipment and the government's localization target for flue gas desulfurization equipment will provide a huge market space for domestic power environmental protection equipment manufacturers. Regarding power plant sewage treatment, it is generally implemented in incremental power projects, and the state has not formulated clear development targets for this. As the proportion of new national power construction projects in total investment in power construction will tend to decrease, the prospects for the development of this business are not as broad as those for flue gas desulfurization. At present, the market structure of domestic power plant water treatment has been highly concentrated. Among them, Kaidi Power (0939) has basically occupied 100% market share in power plant condensate treatment business, and also has 30-40% of power plant sewage treatment business. market share.

The environmental power industry with waste power generation as its core also has a broad market prospect. Given the good social and economic benefits of waste-to-energy, major cities in China, such as Beijing, Guangzhou and Shanghai, will implement waste-to-energy projects and have been approved by the planning department. The operating costs of waste power plants mainly include the cost of waste pretreatment and power generation and operation. The revenue comes from electricity sales and government subsidies for waste treatment. The degree of government subsidies obtained is of crucial importance for determining the investment rate of return of waste power plants due to the large size of the country. The garbage pollution in the medium-sized cities is generally more serious and urgently needs to be resolved. This allows the waste-to-energy plant investors to be in an advantageous position in negotiating the amount of subsidy, and they can often receive preferential treatment for preferential access to the Internet in the sale of electric power products. In addition, waste-to-energy generation has strong economies of scale, possesses exclusive occupation of waste resources in the region, and can effectively control operating costs. It is expected to avoid the frequent fluctuations in operating costs of coal-fired power plants and stabilize operating performance. More sexual.

The potential attractive prospects presented by the power environmental protection and environmental protection power are attracting a steady stream of capital investment. In addition to professional electric power environmental protection companies, many power generation listed companies have also heavily invested and have received positive responses from investors (see Tables 1 and 2). With the trend of environmental protection in the electric power industry becoming more and more popular, it is expected that more and more listed companies will enter this industry and bring about substantial returns.
