　　Third, warm tips

　　At present, Sanya City is carrying out disposal work such as flow tracing, isolation control, nucleic acid detection and medical treatment in an orderly manner. The general public are requested not to believe in rumors or spread rumors. The news about the epidemic will be subject to the official release. They will continue to enhance their awareness of prevention, wear masks scientifically, wash their hands frequently, keep a safe social distance, avoid crowding and gathering, cooperate with the implementation of sweeping the floor and counting yards, and vaccinate Covid-19 vaccine as soon as possible.

　　Building a new power system is one of the important measures to realize the double promotion and double stability of energy security and clean transformation. With the increasing output of solid waste and the accelerated transformation of its disposal methods, waste incineration power generation has injected new vitality into the construction of new power systems. In 2022, the National Development and Reform Commission and other departments clearly put new domestic waste incineration power generation projects into green electricity trading, and the significance of waste incineration power generation was continuously recognized and valued.

　　New engine for new power system construction

　　On the one hand, garbage incineration ensures the safe development of new power systems. Waste incineration power generation can provide stable and continuous power output for new power systems. Compared with other new energy power generation methods, garbage incineration power generation breaks through the limitations of external natural factors and can ensure the stable operation of the power system. Effective garbage disposal and energy conversion can provide important energy supplement for the power system, which will help to accelerate the substitution of new clean energy, break through the limitation of energy resource endowment to some extent, reduce the dependence on traditional energy, and meet the basic premise of building a safe and efficient new power system.

　　On the other hand, waste incineration power generation promotes the low-carbon construction of new power systems. Garbage incineration power generation technology can not only ensure energy supply, but also reduce carbon emissions. Through high-temperature incineration, harmful substances in garbage are completely destroyed and environmental pollution is reduced. At the same time, it can realize the reduction, recycling and harmless treatment of garbage, effectively alleviate the environmental pressure of "garbage besieged city", and at the same time, transform the chemical energy in garbage into clean electric energy, which perfectly meets the development needs of green and low-carbon new power systems.

　　At the same time, waste incineration power generation optimizes the cost structure of new power system. By burning garbage to generate electricity, the garbage originally regarded as waste can be converted into valuable energy, which reduces the cost of garbage disposal. Compared with other energy supply methods, the operating cost of waste incineration power generation is relatively low, which can reduce the overall operating cost of power system. In addition, with the continuous progress of technology and the continuous expansion of scale, the economic benefits of waste incineration power generation projects in promoting employment and improving investment environment will be further highlighted, thus providing more competitive energy solutions for the construction of new power systems.

　　There are still multiple constraints on development.

　　First, it is difficult for the public to trust, and there are hidden dangers in the neighborhood effect. Whether it is landfill or incineration, garbage disposal will produce certain soil, water and air pollution, which will further affect the health and quality of life of surrounding residents. Although the relevant units have limited the negative effects caused by incineration to the greatest extent through technological innovation and process improvement, the public still has panic and rejection of garbage incineration plants for their own interests. In recent years, environmental complaints about garbage incineration have been increasing continuously. This neighborhood effect is not only reflected in the concern about environmental pollution, but also involves the consideration of the value of real estate, which makes the public’s acceptance of waste incineration power generation projects low.

　　Second, the relevant technologies are not mature enough, and the conversion efficiency is difficult to guarantee. Due to technical limitations, the energy conversion efficiency and power supply efficiency of waste incineration power plants in China are difficult to reach the ideal level. Relevant statistics show that the energy conversion efficiency of waste incineration power plants is only 63% of that of traditional thermal power plants, and the power supply efficiency is only 56% of that of traditional thermal power plants. In addition, at present, the method of mixed collection and removal is still mainly used in garbage collection in China, which leads to the complex composition of garbage and the doping of a large number of non-combustible components, which further lowers the calorific value of garbage and further restricts the efficiency and effect of garbage incineration power generation.

　　Third, there is not enough talents in the industry, and there is resistance to sustainable development. With the high-quality acceleration of the construction of new power system in China, the demand for interdisciplinary talents between garbage disposal and new power system industry is increasingly prominent. It is estimated that the current demand for industry-related talents is about 30,000. However, the supply and demand of talents in the waste incineration power generation industry are characterized by insufficient total amount and structural shortage. On the one hand, the industry is developing rapidly, and the external talent supply can’t meet the demand growth of the industry. On the other hand, the ability and quality of existing employees and entry personnel do not match the actual needs. In terms of industry talent training and reserve, China’s universities lack a special training system for waste incineration power generation, which leads to the lack of professional talent support for the sustainable and high-quality development of waste incineration power generation industry in the future.

　　Fourth, the guarantee mechanism is not perfect and the market operation needs to be standardized. With the strong support of national policies, China’s domestic waste incineration power generation industry has developed rapidly, and the accumulated and newly-added installed capacity is increasing year by year. In 2022, the newly-added installed capacity of domestic waste incineration power generation reached 2.57 million kilowatts, and the accumulated installed capacity of domestic waste incineration power generation nationwide reached 23.86 million kilowatts. However, as the capital boom gradually cooled down, local finance continued to tighten, market competition became increasingly fierce, and new projects became increasingly saturated. Problems such as blind expansion of scale, extensive management, low operating efficiency and uneven development of waste incineration power generation enterprises in the early stage have gradually emerged. The operation of waste incineration power generation industry needs to be further standardized to ensure market vitality and durability.

　　Take multiple measures to promote the progress of the industry

　　First of all, in-depth treatment of incineration pollution. First, reasonably raise the emission standards of incineration pollutants. By monitoring the average emission concentration of particulate matter, sulfur dioxide and nitrogen oxides from regional garbage incineration enterprises, we will strictly formulate cleaner pollutant emission standards suitable for this region and limit pollutant emissions as much as possible. Second, the waste incineration plant should be located reasonably, which should be technically feasible, economically reasonable, environmentally acceptable and acceptable to the public, not only to avoid adverse effects on the environment and human health, but also to consider economy. The third is to establish a set of public participation and effective communication mechanisms. The government should institutionalize, standardize, program and legalize environmental monitoring information disclosure, public opinion surveys and hearings, and enterprises should provide complete information to the government and the public as much as possible to eliminate the influence of information asymmetry on public psychology and government decision-making.

　　Secondly, strengthen the innovation of core technology and major equipment application. The first is to strengthen clean and efficient power generation technology. In order to improve the efficiency and quality of garbage power generation, and at the same time pay attention to improving environmental friendliness and reliability and stability, and promote the positive role of garbage power generation in the construction of new power systems. The second is to strengthen the research and development and application of safe and stable power generation technology. Efforts should be made to improve the safe and stable operation level of garbage power generation system, enhance its power supply guarantee ability and flexible adjustment ability, and provide strong support for the stable development of garbage power generation industry by promoting the wide application of safe, flexible and economical energy storage technology. The third is to build a technology research and development system of independent innovation. It is suggested that scientific research institutions such as State Key Laboratory, Engineering Technology Research Center and National Energy R&D Innovation Platform should be built with high quality. By coordinating science and technology, education and human resources, the assessment and incentive mechanism of scientific and technological innovation should be improved to stimulate innovation vitality and promote technological progress and industrial upgrading of garbage power generation industry.

　　Thirdly, deepen interdisciplinary research and personnel training. The first is to promote the deep integration of upstream and downstream industries and technologies. For the special industry of waste incineration power generation, policy support is indispensable, and incentives such as subsidies and tax incentives can attract and retain outstanding interdisciplinary talents. The second is to strengthen discipline construction. We should not only train professionals in colleges and universities, but also provide them with rich practical opportunities to accumulate experience in practical application. The third is to improve cross-disciplinary communication and cooperation channels. By strengthening exchanges and cooperation between different fields, more people can understand and master the knowledge and skills of garbage disposal and new power system construction, and realize the deep integration and development of the industry.

　　Finally, accelerate the improvement of relevant supporting policies and guarantee mechanisms. First, build a green, low-carbon and competitive industrial system, promote the market-oriented reform of monopolistic competitive links, further liberalize the power grid construction business, and stimulate market vitality. The second is to improve the advanced and efficient industry governance system. Strengthen the leading role of power planning, give full play to the guiding role of market mechanism, and ensure the safe and reliable supply in the process of power transformation. Create a fair market environment, rationally use administrative adjustment means, and strengthen the overall coordination and supervision of power planning, construction, operation, trading, price and other links. The third is to solve the financing problem of SMEs. By enriching the medium and long-term loans of enterprises and expanding direct financing channels, the long-term financing needs of garbage power generation enterprises can be met and the necessary financial support can be provided for their development.
