North China has entered the heating season one after another, and many places have been turned on for heating in advance—
This winter, keep the heat right
According to the twenty-four solar terms of the traditional lunar calendar, November 7 is “Li Dong.” North China has entered the heating season one after another. In the context of the standardization of epidemic prevention and control, doing a good job in winter heating is an important event for subsistence in the implementation of the task of the “six guarantees”. What measures have been taken this year to guarantee heating in winter? Can the power supply be maintained? The author will find out for you.
“Heat up” earlier
In winter, the indoor temperature is not only an intangible data set, but also an important indicator related to people’s basic livelihoods.
Guo Ziqi lives in Changchun, Jilin. Going into October, as the weather turns colder, you’ve been expecting a bigger “temperature difference” between indoors and outdoors.
“To be honest, the days before heating are more difficult. The northeast is cold early. I always turn on the air conditioning before going home to warm myself when I get home. Even at home, I wear heavy pajamas. Guo Ziqi said that geothermal heating is widely used in the local area. After the heating began on October 25, the temperature in the home quickly rose to 26 degrees. “It’s warm and comfortable. It’s hot when you enter the house. You can finally put your normal pajamas back on. You don’t have to worry about catching a cold in the bathroom, and the house is no longer humid!”
With the exception of Jilin, many regions have advanced the heating time according to the temperature situation to ensure that residents enjoy a warm winter.
Tianjin announced that it will officially supply heat this winter starting at 0:00 on November 1, and all heating companies will use their full capacity to ensure the sustenance of heating this winter. This is also the fifth year in a row that the city has started central heating ahead of schedule since implementing flexible heating in 2016. Sun Yang, who works as a teacher in Tianjin, just became a mother in July this year. . When the weather turned cold earlier, she was particularly worried that her son would catch a cold. After the heating started on November 1, her hanging heart finally let go. “Suddenly the weather turned cold and I was afraid the baby would get sick so I was only able to wrap him in thick clothes. This year I wanted to warm up early so I wouldn’t have to wrap the house in clothes so thick inside and outside and wash the clothes. Put it on the heater and it will dry out soon. ”Sun Yang said that after the heating, the living and working conditions are better.
On October 25, the city of Shenyang began a hot test operation of the heating system. To ensure the heating effect, the total investment in the repair and renovation of heating equipment and installations in Shenyang this year was 680 million yuan, and 432 boilers were overhauled. During this heating period, the Shenyang heating unit plans to store 8.26 million tons of coal. The coal storage rate is expected to reach 90% by the end of December, which will provide sufficient guarantees for the proper functioning of the heating system.
In response to the continued occurrence of low temperatures, Lanzhou City started the hot pipe heating cycle on October 27, and the heating network system gradually warmed up. With the opening of Lanzhou Thermal Power Company for heating, the heating area of nearly 12 million square meters in the heating area of the “second heat pipe network” in the east of the city is gradually “heating up”.
Beijing also began heating on November 7, which is more than a week before the heating season that usually begins on November 15.
Ensuring sufficient power supply
Timely and effective heating requires a sufficient energy supply. Meng Wei, spokesman for the National Development and Reform Commission, said that at present, the National Development and Reform Commission has made comprehensive arrangements and arrangements for power supply. In general, the supply of natural gas resources is relatively sufficient and the balance between supply and demand is generally better than in previous years.
Preparation is in place, which concentrates on three aspects.
One is to ensure a stable supply. Relevant departments have organized major oil and gas companies to increase resource mobilization efforts to ensure stable and increased production of domestic gas fields, promote diversification of import sources, and ensure that construction of key pipeline networks and interconnection projects are brought online as scheduled. During the heating season, according to changes in supply and demand, a reasonable gas production plan will be arranged to ensure maximum shaving needs.
The second is to protect key objects. China has made it clear that it strongly supports winning the battle to defend the blue sky, increasing support for the supply of clean heating resources in the seven northern provinces and cities and ensuring orderly gas demand from coal to gas. Increase the supply guarantee for key areas and key users in the northern region. Urge all localities to continue including gas buses, taxis, etc., in the field of protection of gas for civil use.
The third is to strengthen emergency protection. Faced with the different extreme situations that may arise, the emergency protection plan is refined and the safety inspection of gas supply facilities is reinforced. Organize locations and businesses to further enhance the roster of 300 million cubic meters of non-resident users who can interrupt the shaving spike and start in an orderly manner when needed to ensure key gas needs such as people’s livelihoods
In practice, large state-owned companies have played a key role in stabilizing energy supplies and guaranteeing heating oil.
According to relevant sources from China National Petroleum Corporation, they have been deployed early to ensure the supply of energy and fuel for the national heating season. In terms of independent production, CNPC Changqing Oilfield has strengthened the fine management of gas wells. On the one hand, it fully borrows modern smart technology to establish a complete dynamic monitoring system to capture the operating status of gas wells in real time; on the other hand, it conducts pull-net inspections and implements each well. Differentiated “sanitary measures” to maximize production from a single well. Since 2020, the rate of opening of gas wells has remained at around 97%, and the rate of decline has been controlled by 20% to ensure effective production of gas wells in winter.
In terms of energy imports, China National Petroleum International Business Co., Ltd. closely monitors the import progress, actively coordinates import plans, and strictly supervises the transfer of metering. Since September, the company has repeatedly connected with various gas sources to ensure the supply of natural gas in winter. Among them, the annual import plan is inclined to winter and the winter import plan is inclined to the high month, and the planned quantity is repeatedly connected with each gas source to ensure the security and stability of the resource supply. At the same time, PetroChina has closely communicated with resource providers such as Shell, Mobil and Qatar Gas, continued to optimize and adjust shipping schedules, carefully analyze supply and demand for various resources and markets around the world, and was always ready. to complement the spot.
Protect people’s livelihoods with “full firepower”
To heat this winter, not only an adequate supply of energy is required, but also the smooth functioning of the entire chain, such as heating companies and transport companies.
Since October 5, the heating companies affiliated with China Huadian Xinjiang Company have successively started supplying heat in advance.
Behind the “full fire” is a lot of hard work. It is understood that since the heating season of the previous year, the company’s heating units have already started preparations for heating this winter. Carry out purification of the heating system and combined transport, inject water into the heating pipe network, pressurize the system, analyze the operation of the heat exchange station equipment and the working conditions of the hot water supply. A series of tasks are continuously executed to ensure the system meets heating standards on time.
In Heilongjiang, Huadian Energy, with a total heating load of 115 million square meters, is the largest local heating company. To ensure that residents live a “warm winter”, Huadian Energy has also carried out the treatment of the heating system in advance, accumulating a total of 17.85 kilometers of old first and second level pipe networks, replacing 121 valves lax shut-offs and greatly enhancing the safety capabilities of the heating. At present, Jia Thermal Power Station under the jurisdiction of Huadian Energy has opened the plug for heating 9 days in advance. Qire Company, Harbin No. 3 Power Station and Harbin Power have delivered heat to users’ homes a week in advance.
The train ran on the tracks, sending coal to the destination. According to information released by China National Railway Group Co., Ltd., in October, China National Railways completed the coal loading of 2.24 million vehicles and shipped 157 million tons of coal; the average daily coal load was 72,400 vehicles, an increase of 1,181 vehicles or 1.7% over the previous month; It distributed 5,005 million tons of coal, an increase of 69,000 tons or 1.4% month-on-month. Coal storage in major power plants and ports across the country has been stable at a relatively high level, effectively guaranteeing the supply of coal in the winter coal market. Among them, the northeast region received an average of 700,000 tons of coal per day, an average increase of 60,000 tons, or 9.4%, month-over-month. Currently, there are 60.2 million tons of coal stored in 350 direct rail power plants across the country, an increase of 5.7 million tons since the end of September.
Heating directly improves the happiness of residents.
Xin Deyuan is a graduate student at Beijing Normal University. In the last two days, the school began testing the heating and also set a new schedule. “With the heating, you don’t have to worry about getting up, you don’t need to cover too much in the bedroom, and it’s comfortable and convenient to go to the classroom to study. I’m preparing for my thesis!”
“After geothermal heating, the whole house will have a constant temperature, and every corner of the kitchen, bathroom and bedroom will not be cold. It is winter outside, but the house is like spring. The quality of life is can seize! “Changchun Citizen Mu Baojia Happy.
Many popular tourist destinations in Northeast China are already preparing to welcome snow watchers.
