Xinhua News Agency, Beijing, November 7 (Reporter Chen Xu and Guan Guifeng) On the 7th, according to the deployment of heating work, Beijing officially entered the trial heating stage, and the regional boiler room began to ignite the trial operation.
How effective is the heating trial operation in Beijing?
What should I do if it's "closely hot and far cold"?
The reporter walked into the heating workshop of Beijing Thermal Group to search for answers.
At the East Lake Heating Service Station of Beijing Thermal Group, two boilers have been ignited and operated, and the staff are operating on the monitoring platform to ensure the smooth operation of the equipment.
In the boiler room, there are several other equipment on standby at any time.
According to the on-site staff, based on historical data and weather trends, the Thermal Group has formulated multiple sets of heating start-up plans, operation plans and multiple emergency plans to achieve scientific command and preparedness.
Hu Di, deputy director of the Heating Office of the Beijing Municipal Management Committee, introduced that from the 7th, all heating units in Beijing will conduct ignition debugging and inspections. The system will be pressurized, watered, and kept hot. Residents’ homes are gradually heating up. Stable heating is reached until the formal heating.
8 thermal power plants, 7 Jianfeng heating plants, 3 emergency guarantee heat source plants and 2 temporary emergency heat source plants provide heat sources for the municipal heating network, with a total heating capacity of 9128 MW... As the largest heating company in Beijing, Beijing Thermal Group manages 324 million square meters of heating area, accounting for 36% of Beijing's total heating area.
"After using the 5G Internet of Things to strengthen room temperature monitoring, our adjustment has "eyes"." said Wang Jiaming, manager of the heating production department of Beijing Thermal Group, in order to solve the problem of system heating balance, since 2019, according to the needs of adjustment, they have divided Category: Install more than ten thousand 5G temperature measuring boxes in the distance from the heating station, the high, medium and low residential floors, and the yin and yang sides of the building, and connect the data to the "weather forecast and room temperature monitoring platform", integrating multiple temperature measurement modes, real-time Master the heating temperature of the user's home to ensure the heating quality.
Ms. Pan, who lives in Jinshijiayuan, Dingxiu, Fengtai District, Beijing, said that last year the community installed an artificial intelligence heating network control system as a pilot, and the phenomenon of hot and cold heating disappeared.
According to reports, "near heat and far cold" are mainly caused by the poor secondary water supply cycle caused by residential heating system design problems and aging facilities, which usually require manual large-scale adjustment.
The artificial intelligence heating network control system can automatically adjust the valve pressure and flow rate of each unit of the heating network, making it more accurate and efficient.
In recent years, the intelligent characteristics of the Beijing heating network dispatching system have become more and more obvious.
For the first time this year, Beijing Thermal Group applied the "heating network online simulation system". By combining production monitoring data, geographic information data, weather forecast data, and room temperature data, it performs heat load prediction and dynamic simulation of pipe network operating conditions to achieve on-demand adjustments. Thermal and dynamic balance.
This not only ensures the safety of the pipe network operation, but also ensures that the user's heating quality meets the standard.
"Judging from the number of '96069' heating service hotlines, the current trial heating is running smoothly." He Yingxi, the director of the customer service center of Beijing Thermal Group introduced.
"Winter disease and summer treatment" is an important link in the renovation and maintenance of the heating system.
According to reports, in 2020, Beijing Thermal Group will overcome the impact of the epidemic and complete nearly 70,000 related renovation projects such as maintenance, technical renovation and blanking, 135 kilometers of pipeline network maintenance and renovation, and comprehensive management of 92 heat stations to provide heating work this winter. Good protection.
