"In previous years, the biggest worry was the windy day. Every winter when the wind blows, the sky is full of coal ash and cinder, and the environment is very bad, and even received complaints from the public. "Since the coal-to-electricity transformation project has been rapidly implemented in the suburbs of Beijing, we have carried out in-depth cooperation with Yankai Energy, a new energy company, and carried out clean energy transformation of coal-fired boilers. Air pollution here has been greatly reduced and people's living environment has been further improved." In the face of Beijing TV "Live Beijing" reporter interview, Fangshan District Dashi Wo Town deputy mayor Sun Weidong quite emotional.
Speaking of coal to electricity, people are familiar with. As an important project of energy conservation and environmental protection, energy conservation and emission reduction, and environmental pollution improvement in the northern region, it has been deeply rooted in people's hearts and achieved gratifying results in various regions.
"We will use clean energy as much as possible and speed up the increase in the proportion of clean heating." ; "We will accelerate efforts to solve the problem of pollution caused by coal burning, comprehensively implement comprehensive treatment of loose coal, and promote clean heating in winter in northern China". In recent years, the central government has been very determined to clean up the environment, and promoting the process of converting coal to electricity and improving the quality of life of residents is also very popular among the people.
Remarkable progress has been made in upgrading coal-fired energy boilers
Since the beginning of the "coal to electricity" project in Beijing in early 2000, the project has been implemented in the city and the new district for nearly 16 years. At present, Beijing has basically realized coal-free heating in urban areas, and coal-free heating in the plain areas of the city is expected to be realized by 2020. Nowadays, with the rapid progress of the "coal to electricity" process, clean energy transformation and comprehensive treatment of loose coal have radiated to many suburban counties, Beijing Fangshan District is one of the typical areas. Thanks to the switch from coal to electricity, residents of Fangshan District no longer have to worry about burning boilers and filling the sky with ash in winter. Among them, in addition to the determination of the government and people to the environmental transformation, the active help of new energy enterprises that use high-tech to provide comprehensive services, is also an important factor for Fangshan District to achieve gratifying results.

As the first high-tech enterprise registered in Zhongguancun Development Group, a high-end manufacturing base in Beijing, Yankai Energy has obvious advantages in electric energy replacement technology, comprehensive utilization of off-peak electric energy and other technologies. Due to its ability to provide the whole industrial chain services of coal-fired boiler replacement and transformation, electric energy storage boiler heating and other energy projects, Yankai Energy has made outstanding achievements in the field of electric heat storage and heating in recent years. And Fangshan, the core area of Beijing's "coal to electricity" project, is Yankai Energy's key business area.
According to the survey, by the end of last year's heating season, more than 100 enterprises and institutions, including 70 kindergartens, nursing homes and schools, had carried out clean energy heating renovation under the leadership of the local government. According to comprehensive calculation, Fangshan District can reduce coal consumption of about 30,000 tons, reduce carbon dioxide emissions of 70,000 tons, reduce carbon slag of 7,500 tons, reduce smoke emission of 360,000 tons every year.
Liu Guobin, director of Yankai Energy, said that since many remote areas in Fangshan District have no gas pipeline laying, the use of canned gas has transportation problems and safety risks, so the coal to electricity clean energy transformation project is particularly suitable for the suburban areas of Beijing, as well as the northern areas where the gas pipeline has not been laid.
So, how effective is the transformation of coal-fired boilers?
Sun Weidong, deputy mayor of Dashiwo Town in Fangshan District, said: "Originally, our annual heating cost is about 800 to 1 million yuan. After the coal to electricity boiler is changed, our cost is now about 640,000 yuan. Therefore, this has greatly reduced the operating costs of our government and reduced fiscal expenditure. On the other hand, in terms of environmental protection, there is no smoke and dust. And the boiler is low-carbon and environmentally friendly."
The "boiler" mentioned by Sun Weidong refers to the solid electric energy storage furnace created by Yankai Energy, which is a high-tech product integrating heating, energy storage, heat exchange and electric control technology. This kind of solid heat storage centralized electric heating technology application, not only the equipment is simple, under certain conditions can be unattended, the most important is that there is no traditional boiler room chimney and coal burning, completely solve the environmental pollution problem of cinder flying everywhere.

Yankai energy director Liu Guobin told reporters: "In the past, coal boiler or gas boiler, it is a time segment, water temperature control is not so accurate, precise and stable. But our solid electric storage furnace heating effect is very stable, its temperature is constant throughout the day, that is to say, our indoor temperature is constant. The common people also feel comfortable using it."
Because Yankai Energy adopts advanced water and electricity separation technology, high voltage control technology and energy storage and insulation technology, it can convert idle electric energy of the grid into heat energy storage during off-peak hours, and then realize continuous release 24 hours a day through the efficient exchange device, with large-scale and super-large-scale heating capacity. So quickly in Fangshan area coverage to open, favored by the local units and people.
However, the reporter also learned that the coal to electricity transformation project in the city has been supported by the government policy, the residential electricity is relatively cheap, which is a good thing. But the energy enterprise electricity policy, but still exist blank. According to the analysis, electric energy is not stored and can be lost even if not used. If the government adopts a policy to convert coal to electricity companies to use off-grid electricity, it will not only save money for the coal to electricity conversion project, but also help the recycling of electric energy resources.

Yankai Energy, for example, uses electric storage furnace as the heat source in the coal transformation project, which can use electricity from 11 p.m. to 7 a.m., and store energy in off-peak hours to provide heat source for the whole day. If the relevant competent authorities of the state give a certain price policy for enterprises and institutions to convert coal into electricity for heating, it can greatly reduce the operating costs, but also make each link in the whole supply chain, the cost can be further optimized, which is very beneficial to all parties, and also has a positive role in promoting the speed of the whole coal to electricity project.
We need all parties to work together to protect our blue sky! Now we are pleased to see that Yankai Energy has made remarkable achievements in the clean energy transformation of coal-fired boilers in Beijing. We believe that with the introduction of more policies to benefit the people and enterprises, and the active participation of all parties, the "coal to electricity" project in Beijing will make even greater achievements.
