The picture shows the ground source heat pump + fan heating, the use of soil, groundwater heat and the building to complete the heat exchange
As of the end of September, the State Grid Corporation of China completed a total of 1.75 million and 5763 village reconstruction tasks with a heating area of over 100 million yuan Square meter.
During the visit to some demonstration areas and village households in Beijing's Tongzhou and Langfang areas, reporters found that after the implementation of the coal-to-electricity project, the advantages of electric heating, such as clean, safe, comfortable and convenient, have brought benefits to more and more people , Not only improved people's quality of life, but also quietly transformed the production and service mode of government and enterprises and enhanced the awareness and ability of innovation in society.
No longer waiting for the coal stove
The over-aged Zhang Wanzong and Liu Shumin, both of whom live in Cuijar Lou Village, Tongzhou District, Beijing, have used air-source heat pumps to heat their homes since completing the coal-to-electricity conversion last year. Serve coal stove.
For the elderly, sooner or later fill the coal, cleaning coal ash is a physical activity .Zhang Wanzong every day it is up to break up the coal block, make a day of coal preparation .Filling the coal regularly, clear the ash every time Now, Liu Shumin on the home electric heating equipment full of praise: 'Look at my house now more clean outside the house, at any time warm and bake.'
Like them, people in the coal-to-electricity area do not need to pile up coal and do not have to deal with coal ash again, both in the family environment and in the village and town environment. At the same time, Residents bring more security.
In the past when burning coal, a large amount of coal burning not only polluted the environment, but also posed a great potential safety hazard for the stacking of dry wood and coal. After the coal was switched to electricity, the power supply facilities were completely upgraded and upgraded, And so on, coal-fired heating caused by gas poisoning, fire and other safety accidents also significantly reduced.
According to reports, the 'coal to electricity' residents after the actual capacity of 6-9 kilowatts, 4-5 times higher than the original, a substantial increase in power supply capacity, people began to widely use kitchen appliances, air conditioners, water heaters and other equipment, Plug and play, ready to break, and even remote control, and effectively enjoy the electrification of convenient life.
While living more modern, some traditional habits are also respected and retained. Many elderly people are sitting on the kang heating every day, and now 'coal to electricity' will directly cancel the 'kang' in the State Grid Tongzhou Cuijia Floor 'coal to electricity' real demonstration area, State Grid Corporation staff told reporters that the 'electric kang' has the advantages of rapid heating, uniform temperature distribution, high comfort, you can also intelligently adjust the temperature, the use of more secure. ' Not our main push equipment, but many villagers take the initiative to inquire about, to be prepared for the elderly home.
'Butler' value-added services more caring
'Coal to Electricity' not only changed people's way of life, but also prompted the government and enterprises to change their working methods so as to win more people's support for the policy with more attentive service and benefit from the project.
At the beginning of the project implementation, the government and power grid enterprises conducted field research and publicity to lay the foundation for the project implementation.Wang Zi Xi, employee of Langfang Power Supply Company of Hebei Electric Power Co., Ltd., introduced to find out the market base of Langfang Coal to Electricity and master the first-hand information , They go to the village cross-family, one by one touch row, the establishment of 'one family one policy' file in order to suit the local conditions for the villagers to provide heating programs.
To handle the new clothes, increase capacity, households do not have to worry about the trouble of the villagers, the company provides a dedicated 'green channel' service, to be accepted the same day, the next day to complete. In addition, they also cooperate with the government to develop a line conversion program , To assist the government in the selection of heating equipment, and take the initiative to provide policy guidance, technical advice, home receptionist application, the whole business agent and other 'housekeeper' value-added services.
Taking into account the 'coal to electricity' will bring a large number of electrical needs, the State Grid has with 2,393 appliance manufacturers to carry out strategic cooperation, organized nearly 10,000 promotional activities, the cumulative promotion of more than 10 million household appliances to promote household appliances manufacturers make profits for 106 million In addition, the government promulgated the 'coal to electricity' resident preferential tariffs and subsidies: residents of residential insulation, indoor renovation and heating equipment to give subsidies to purchase, and give residential heating electricity 0.2 yuan / kWh subsidy, the implementation of peak Valley price, no longer use the ladder price.
Wu Sister, Dongxing Village, Sanhe City, Hebei Province, installed three regenerative electric heaters this year, each with a capacity of 3.2 kilowatts and an entire household capacity of 9.6 kilowatts. Will these facilities bring an extra financial burden to Miss Seng? Langfang Power Supply Company employees to reporters calculations: 'If Sister Wu coal-fired heating, about 3.5 tons of coal each heating season to 800 yuan per ton of coal, the purchase cost of coal is 2800 yuan.While the use of electricity on behalf of coal, Heating season electricity consumption is expected to be 6000 degrees, according to the ratio of 3: 5 peak-valley period, and then deducted government subsidies, then Sister Wu appliances heating costs actual expenditure is 1163 yuan.
New heating technology continues to emerge
General Secretary Xi Jinping pointed out in his 19-nation report: 'Innovation is the first impetus to development and a strategic support for building a modern economic system.' 'We will speed up the process of' converting coal to electricity 'and carry out the process of replacing coal with electricity in various ways, Electric heating equipment and key technology advances and innovation put forward higher requirements.
Under the promotion of national policies, the heating area of 'Coal to Electricity' continues to expand, and electric heating equipment and key technologies continue to make progress and breakthroughs. In addition to Zhang uncle's air-source heat pump heating, Wu Sisi's regenerative electric heaters, There is also a new batch of heating technologies such as nano-crystallite thermal storage and phase-change energy storage that are emerging continuously. The energy cascade utilization technologies such as 'regenerative electric boiler + heat pump' and 'industrial waste heat + electric boiler' According to statistics, only the market size of coal to electricity in Beijing reached over 5 billion yuan in 2016. The market demand has stimulated enterprises to create vitality and spawned a group of well-known brands and enterprises.
State Grid Cui Building, Tongzhou 'coal to electricity' demonstration area is like a real laboratory demonstration of the two yards showing a variety of electric heating equipment through smart capture terminal access to the monitoring platform, real-time transmission of the operation of these devices , Room temperature, humidity and other data for staff to analyze the heating performance of the equipment.
Innovative methods also improve work efficiency.Wang Hao Xuan of Langfang Power Supply Company referred to the concept of 'factory-made prefabrication': 'The complete set of materials is decomposed into modular prefabricated and four high-voltage lead-making modular prefabricated platforms are adopted Cutting and other means to complete the pre-production of components through which you can quickly and standardize the completion of a variety of equipment manufacturing and installation. 'This method is widely used in the' coal to electricity 'project site, the variable installation efficiency Nearly 40%, and is expected to form a variety of national patents 15.
