Tianjin has officially provided heat and journalists are visiting the residents' homes
Is the heat hot enough to warm up
On 13 november, the city of tianjin officially provided heating. From 0000 hours on the same day, the heat units were warmed up and the citizens warmed up the winter。
Is the system stable during the initial heating period? Is the heating of the citizens’ homes rising in time? Journalists have made field visits。
Enhancement of energy reserves and early rehabilitation of network overhaul facilities
"it's hot, it's good." on november 13, early in the morning, shen jie, who lives in the peace zone in tianjin city, touched the heating tablet and looked at the thermometer, "at 23. 2 degrees celsius. It was hot the other day." shen jie's house is more than 40 years old, and “the heating is later installed, old buildings are less warm, so i keep an eye on the heating every year as soon as i get there”
“the situation is normal.” late in the night of 12 november, the operator of the chen tong thermal power company, tianjin energy group, and his colleagues lee gao yang and li jianhui came to the plant to check the fluids of the heat grid and check the decomposition of the heating grid to supplement the hydroelectricity door. On the screen of the production movement centre of tianjin energy group, all types of heat delivery data are being displayed in real time。
“we plan early on before the heating season to prepare a fuel procurement plan and a phased reserve, using a multi-source approach to ensure a stable supply of coal. “the deputy general manager of tianjin energy group gave a presentation to kim tong. Using this year's renovation period, tianjin energy group completed 396 km of retrofitting of the old heating network, which was 6. 6 times greater than in 2023; completed 5720 equipment facility overhauls, 1,452 heat exchange units, 3676 serial systems retrofitting and 4108 household in-house cleaning; and carried out spot visits and follow-up services for all 415 primary and secondary schools and health-care institutions in the district, among them 91 heating guarantee upgrades。
Prior to the official launch of heating on 13 november, all 574 heating stations in tianjin city had completed the indoor ballasting of water, house-based filter cleaning and cold-state recycling operations, and the heating stations had begun thermal commissioning again on 7 november. In the heat season, tianjin has replaced or repaired 4891 heaters, 7105 pumps, 3639 gas alarm devices and 15931 pressure tables. The city-wide heating network has been upgraded totalling 1086. 85 kilometres and the winter and summer treatment home heating facilities totalling 7638 households。
Set up a heatist. Residents can contact directly in case of failure
On the night of 12 november, after receiving a copy of the order of work from the heat-service house of the anthem first heating centre in the city of tianjin energy group, and the co-worker, heated pipes in the ryodu garden in the west of the river. At the scene, the pebbles quickly determined the point of failure and removed the leak in time, and a detailed check was made of the potential risk points in the vicinity. “the tarp is in trouble and has been repaired.”
This year's hot season, the city of tianjin has fully promoted the system of heating housekeepers, organized the establishment of heating housekeepers in sub-districts throughout the city, was responsible for the heating service for residents of the district, and the joint network staff made public information on the names, photographs, contact details and range of services of heat housekeepers in various channels, such as community information boards, building entrances, etc., to ensure smooth communication of heat housekeepers. The total number of heating housekeepers is 1611, with a maximum of 4,000 households per housekeeper。
Heating is a matter of concern to thousands of families, and various heating units in tianjin have launched targeted service initiatives for the different characteristics of the population。
"we're too old for smartphones, sometimes we can't hear the phone, and it's too easy for the heat to press the 'not hot' or 's leak' buttons!' “before the heating season, the heating enterprises of our organization actively connected to the streets of the heating service district and registered the information of users over 75 who needed it. At present, 1,045 terminals have been equipped for older users over 75 years of age in heating areas.” liu hwanzhi, deputy manager of the energy industries department, tianjin energy group, explained that each terminal had a user address bound, that the heating intelligence passenger service system automatically formed a worksheet after the elderly pressed the key, and that maintenance staff contacted the users and examined them on site within 30 minutes。
Shen riong, who lives in the bei hae-hyunten quarter of the new coastal area, came to the window with journalists, and the new heating pipeline downstairs was located at the entrance to the residential building, where the thermometer indicated an indoor temperature of 23°c。
“this is an old sub-district, previously laid by a ground-laying network, which in recent years has suffered from severe corrosion at bends, welding and patches and has begun to cause concentrated leaks. This, together with the conversion of 60 per cent of the population to heating, resulted in a severe water balance disorder. In the early part of last year's heating season, the loss of water pumps affected the overall heating effect of over 2,700 households in the sub-region.” “this situation must be re-engineered and optimized during the non-hot season `winter and summer treatment', according to ma mengjun, manager of the new heating zone sanctuary company ltd
This summer, businesses used the summer super-long national debt, the epc, to invest more than $8 million in the rehabilitation of the bei hae hae-teng district, laying pipelines of more than 10,000 metres and supporting shelves of more than 500. “we spoke repeatedly and in coordination with the new village streets, the community and the industrial commission to define the renovation programme, to proceed with the construction work on 21 september, to complete the main plumbing on 23 october and to complete the cold cycle on 28 october, thereby overcoming the system's water loss.”
Explore the measurement of heating, how much heat households spend money
As new technologies such as grid imitation, big data, smart equipment and so forth are fully integrated into the heating field, the heating systems such as heat sources, networks and so forth have been overhauled in some areas of tianjin. A “cool heat” intelligent heating system is playing a greater role。
The deputy director of the production and movement control centre of tianjin eco-city energy construction limited, yang sholong, has three giant screens in front of him, with changing information on site environmental monitoring, temperature heat in sub-regions, heat exchange station operational status, location of transport personnel and real-time monitoring by staff to ensure the proper functioning of the heating system. “this is an autonomously developed intelligent heating system that combines weather conditions, outdoor temperatures and user heat, automatically adjusts temperature valve openings to provide precision, heat-on-demand, and ensures warm and energy-saving simultaneously.” in his presentation, yang xiaolong described the system as covering heat sources, pipe networks, pumping stations and user level 4, which would be managed in three stages of production, fee collection and passenger service。
The reporter followed wang zheng, the heating director, to a district heating station. “this heat-replacement station serves 732 households and provides more than 75,000 square metres of heating. “open the door lock, and wang qi goes straight to the pump and scrutinizes the parameters, “all stations are equipped with such electric control valves. Today's patrol has been six times a day and only two times now. Dispatchers will be able to give instructions to all heat-replacement stations throughout the area within 10 minutes of the dispatch hall and the temperature can be adjusted to a positive or minus 0. 5 degrees celsius. In contrast, traditional manual regulation takes 10 people, six hours, and the temperature regulation is based on the individual's sense of hand and experience.”
At the end of the inspection, wang jing went to the other side with journalists to check on the actual heating. "i like to feed little animals." resident zhang dawei welcomed journalists into the house, and over 80 square metres of small homes were alive. "i stabilized the heating temperature at 22 degrees celsius by measuring the terminal, saves money and is warm."
In 2013, heating in eco-cities began with the arrival of the first inhabitants. At present, eco-cities are promoting heat-measurement throughout the country, with heat-measurement tables installed in the homes of residents to adjust the heat to actual needs. The autonomous regulation of how much heat is spent and how much money is paid by the population has also encouraged the heating enterprises to proactively allocate them in order to avoid waste of energy and reduce the consumption of the heat per unit。
According to eco-cities statistics, thermal measurement is a 5. 82 per cent reduction in the consumption of thermal energy per unit of eco-city under the eco-city charge model, with 15. 8 per cent savings compared to the traditional cost model. (reporters, kimberly, lee jia-ding)
Tibet tsajiki county concentrates on heating using clean energy, and residents ' homes are rehabilitated
"with a heating chip, every house is warm."
The cold winds are whistling, and the temperature outside of the ari district of the tibet autonomous region, which is 4,700 metres above sea level, has reached below 10 degrees celsius. The residents of the county, migudoje, walked into their homes from outside, and could not wait to take off their thick tibetan robes and pour a hot cup of tea and drink it warmly。
“cow manure was previously to be burned during the day, warmed only by the stove, and other houses were cold. Especially when it comes back from the house, the stove goes out and it has to be lit again, and it takes a long time to heat up in the house.” migudorgi said, "with a heating chip, every house is warm."
At first, mijodoge had doubts about the heating tablets in his home, and it was difficult to warm up the whole house with this little piece of iron, "i don't believe it at first." now you touch it, it's hot!"
Subwanrob is a maintenance worker at the heating company and a local on duty. During this period, he was rehearsing the heating tablets at herdsmen's homes on an almost daily basis. In response to the needs of the parents and their families, the second wangroub family helped them to solve the problem and spoke patiently about the use of heating。
These are the projects for the centralization of clean energy for heating, which have just been shipped this year. For eight months of the year, the tsalaka county was dry. Previously, biomass hot-water boilers were used in counties to provide concentrated heating, with high energy consumption and operating costs, and when biomass fuel is not fully burned, indoor temperatures often reach less than 18 degrees celsius。
Promoting the use of clean energy improves both heating and energy consumption。
In the north-east direction of the town, over 6,000 light volts flash under the sun. Into thermal plants, the wall's smart screens display solar light-heat heating temperature, heat production, heat-supply network pressure, flow and heat supply. These data provide staff with timely access to the operational state of the solar heating system and to intellectual heating。
“in short, we use solar energy to keep water warm and to transport it to areas where it is needed.” the head of solar clean energy supply technology in tsatisco county, li hao qi, said that, after multiple technological safeguards, water storage at thermal plants is now stable between 60 and 70 degrees celsius, and can achieve a steady supply of heat even if extreme weather occurs in one week, keeping the temperature at about 18 degrees celsius in the home。
Li hao described the reduction of co2 emissions by nearly 20,000 tons per year through the introduction of solar centralized heating systems, the reduction of 800 tons of sulphur dioxide emissions and the minimization of pressure on ecosystems from biomass burning sludge。
A total investment of about $314 million was made in clean energy concession projects in urban districts of tsatiya county. Under the guidance of the government, the heating enterprises have adapted the old system in the county cities to provide an additional 56. 9 million square metres of heating。
It is not easy to overhaul the entire county network. “4700 m above sea level, low temperatures, ice, ice, thaws, aging of facilities, many factors make it more difficult to re-engineer the pipe network.” li hway。
During the commissioning of the project, li hao received a telephone call from a community worker, “the district is flooded! He and the technologists immediately went to the community to check on the situation. As a result, part of the underground pipe network has been rusted, and the heating hot water is bursting as soon as it is injected. The hot water sprayed and the ground in the sub-region flooded the “spring”. Li hao li and the technicians are conducting on-site repairs to replace some of the pipes to ensure a smooth heating。
Debugging, repairing, rebugging, re-maintenance were the norm for the time being, li hao-il and his colleagues. “there are many problems, but they are all overcome.” li hao-jee said。
“the county-wide power guarantee works are being carried out to ensure full capacity during the hot season, allowing the population to live warmer and more comfortable in winter. According to liu yonggang, deputy secretary-general of the county commission for the control of censorships。
Such centralized heating rehabilitation projects are not a case in point. This year, tibet has continued to promote the concentration of clean energy, with seven districts (districts) in the ali region gradually completing a clean energy replacement for heating, with plans to build and adapt a total heating area of 6. 2241 million square metres to meet the heating needs of 200,000 inhabitants.

The concentration of heating in towns and cities throughout the country amounted to 13. 7 billion square metres
2. 01 billion square metres in the last three years
The head of the relevant department of the ministry of housing, urban and rural construction explained that the traditional areas of the country's cities and towns that provide heating for the heat are those of the north, mainly in the form of concentrated heating. By the end of 2023, there was a concentration of 13. 7 billion square metres of heat in towns throughout the country, including 11. 5 billion square metres in cities, 2. 2 billion square metres in county towns and 2. 01 billion square metres in the last three years. The length of the central heating pipeline is approximately 630,000 km across the country, an increase of 119,000 km over the last three years。
According to the 2023 communiqué on the state of urban construction in china, three provinces, shandong, liaoning and hebei, have concentrated on heating areas of more than 1 billion square metres; eight provinces, heilongjiang, shanxi, beijing, inner mongolia, jilin, henan, tianjin and shaanxi, are between 500 and 1 billion square metres; three provinces, xinjiang, gansu and ningxia, are between 100 and 500 million square metres; three provinces, qinghai, jiangsu, anhui, hubei, guizhou, yunnan, tibet, sichuan, eight provinces and xinjiang, are below 100 million square metres; and nine provinces, shanghai, zhejiang, fuji, jiangxi, hunan, guangdong, guangxi, hainan and chongqing, have no concentration of heating。
The provision of heat and heating in towns and cities is an important human security project and is of vital interest to the people. The head of the relevant department of the ministry of housing, urban and rural construction made a presentation, according to which the ministry of housing, urban and rural construction has organized intensive “winter and summer treatment” in all areas for the purpose of heating and heating in the towns of this winter and spring, making full use of the time-out window, continuously upgrading the capacity of the heating facilities through the expansion of the heating system, overhauling and maintenance of the heating pipeline network, overhauling the user-end problems identified, improving emergency security plans, etc. Continuous promotion of the retrofitting of the heating and ageing network. Since 2022, a cumulative total of 334,000 kilometres of heating pipelines have been completed at various locations, effectively reducing the risks associated with the operation of heat pipelines. To guide local efforts to increase energy reserves for heating. Energy supplies are generally adequate and coal and gas supply capacity has steadily increased, with a higher level of security than in previous years。
We are actively promoting clean heating in the north, replacing coal heating with clean, low-carbon energy sources such as electricity, natural gas, biomass, geothermal and industrial residual heat, with a clean heating rate of nearly 80 per cent in the north by 2023. The white paper on energy transformation in china shows that, by the end of 2023, the area of clean heating in the north had increased by 10. 7 billion square metres compared to the end of 2016, and the rate of clean heating had increased by 46 percentage points; the concentration of pm2. 5 in the surrounding area of kyinzu and the quim plains had decreased by 41. 1 per cent and 30. 6 per cent, respectively, compared with 2016, and the number of heavy pollution days had decreased by 61. 2 per cent and 41. 8 per cent, respectively, and the contribution of clean heating alternatives to dispersed coal to the improvement of the regional ambient air quality had exceeded 30 per cent.
