A few days ago, the reporter was informed that Dongmingzhu, the deputy to the National People's Congress and chairman of Gree Electric Appliances, had a bill in the two sessions this year that caused great concern from the media and the public - "Proposal on Promoting Cleaner Heating by Promoting Coal to Electricity". She suggested that the state should regulate the clean energy transformation work from the policy level and stop blindly selecting 'coal to gas' because of the cost of reforms. It should vigorously promote 'coal power reform'. The reporter believes that Dong Mingzhu’s proposal comes from practice and grassroots reality. With great foresight, in the new era, our country must win the battle to defend against the blue sky, take the road of green development, and achieve clean heating. 'Coal to power' should be the first choice, and priority should be given to the development of electric heating systems for user terminals.
During the two sessions, Dong Mingzhu was interviewed by the media
As we all know, comprehensively implementing comprehensive coal treatment is one of the important means to improve China’s ecological environment and improve China’s air quality. The clean energy work of coal reform is of utmost importance. Promoting clean heating in winter in northern rural areas is of great significance and far-reaching impact.
According to the statistics of relevant state departments, since 2016, Beijing has been the center, in the Beijing-Tianjin-Hebei region, and in North China, the government has introduced relevant financial subsidy policies, and the coal clean energy work has achieved remarkable results. After completing the conversion of coal to electricity, 3 million coal-to-gas conversions were completed. In 2017, a total of coal-to-coal power conversion was completed in the country, and 5.78 million coal-to-gas conversions were completed. The effect is also very significant. From October 2017 to the end of February 2018, '2 +26' The concentration of PM2.5 in the city decreased by 35% compared to the same period.
Although local governments encourage clean energy heating and reconstruction, due to the difference in economic development level, the subsidy policy is not the same. For example, the average per-subsidy in Beijing is 20,000 yuan; Tianjin coal-to-electricity equipment is fully subsidized by the government; Hebei The highest subsidy for households is 7,400 yuan, while in Henan, only 3,500 yuan is subsidized. This results in areas with high subsidies. The reform of clean heating is mainly based on coal-to-electricity. For example, in the clean energy reform in Beijing in 2016, coal-to-electricity accounted for the entire coal reform. 88% of clean energy, coal-to-gas conversion only accounts for 12%. In areas where there are relatively few subsidies, coal-to-coal gas with a relatively low cost is more likely to be selected. For example, in the clean energy reform in 2017 in Hebei, coal-to-gas will occupy A large proportion.
'Coal to Gas' has caused the natural gas shortage in the entire North China region or even across the country in the winter of 2017. The news that the supply of gas in some areas has become a hot topic has also become a hot topic. In addition, the extraordinary growth of natural gas has broken the balance between supply and demand and increased natural gas prices. At the same time, the cost of gas in the later period is high, and the burden on the heating of rural residents is high.
Moreover, the natural gas components used by the people in reality are complex and not monotonous. They belong to fossil energy sources. The combustion of natural gas will produce nitrogen oxides. The use of large amounts of nitrogen will not achieve the expected results. Further, natural gas pipelines Laying for the laying of open pipes has the risk of leaks and explosions. Natural gas explosion accidents in communities have often been reported by the press.
In contrast, 'coal to electricity' is a safer, cleaner and more comfortable way of heating, and under the new normal economy, China’s power production maintains a momentum of growth, and economic restructuring has led to the transformation and upgrading of most enterprises. There is a surplus of electricity in one industry, abundant electricity for people's livelihood, and the rationality and economy of coal-to-electricity, which can simultaneously achieve energy conservation and emission reduction. It is worthwhile to be advocated by the government.
In the coal-to-electricity work, to promote energy-saving and emission reduction and create a blue sky, high-tech air-source heat pumps should be the first choice, not only safe, energy-saving, and environmentally friendly, but also very efficient. The air-source heat pump heating energy utilization rate is much higher than the electric heating form, The high heating energy efficiency and the stability of the low-temperature (-25°C) heating system have been fully confirmed in the coal-to-electricity transformation work in the past two years. It is the preferred heat source for power transformation. Moreover, the air source heat pump has been developed for many years. The perfect product system can meet the room, family style and even large commercial buildings.
The author believes that vigorously promoting coal to electricity and promoting the use of air-source heat pumps by residents will enable residents to enjoy a comfortable winter while also making immeasurable contributions to national energy conservation and emission reduction.
