It's so cold, why not provide heat in advance? The heating department responded like this.

As the heating period approaches and the temperature drops sharply, when can residents keep warm at home? This is a concern of residents.

This morning, Li Xiqing, deputy director of the Municipal Construction Committee, Zhang Bin, director of the public utilities department, Cui Kerong, director of the heating office, Liu Jian, deputy director of the public utilities department, Pei Lianjun, manager of the heating industry department of the Municipal Energy Group, and Zhao Henghai, deputy manager of the gas industry department, made a guest visit to Tianjin News Broadcasting "Public Servants Walk into the Live Room". I will communicate with you around the preparations for all aspects of heating services that you are particularly concerned about, and answer related heating questions at the same time.

What is a cryogenic cycle?

This winter, the central heating area in our city will reach 373 million square meters, including: gas 1 12430 square meters, accounting for 30.4%, up16.2% year-on-year; Cogeneration of heat and power114,585,300 square meters, accounting for 30.7%; Coal-fired boilers 1, 3 1.6 million square meters, accounting for 35.2%, down 1.6% year-on-year. The city's central heating penetration rate reached 9 1%, and the central city reached 97%. In addition, there are geothermal, water source heat pump and air conditioning. Some residents may feel that the temperature at home is a little bit in the past two days, which depends on different situations. If it is a small boiler room, it will be hot in one or two or three days, and 65438+ 10,000 ~ 300,000 square meters will be hot immediately. However, if it is a large boiler room, it takes 5 days to a week from the boiler ignition to the oven drying, and then the water is heated, transported to the heat exchange station, and then sent to the residents' homes. Thermoelectricity takes longer than this. A thermoelectric pipe network is supplying gas 1.34 million square meters, and another pipe network has run for more than 20 kilometers. It takes 7 to 10 days to deliver it to ordinary people's homes. The near end of the pipe network is heated first, and the far end is heated later.

In the case of a sudden drop in temperature, why can't we achieve early heating on a large scale?

There are standards for heating. According to the heating standard, heating can be started when the average temperature is lower than 5℃ for five consecutive days. Judging from this year, last Saturday and Sunday, two cold days, were days for residents to rest at home. Only these two days are below or close to 5℃, and the temperature rises from today until 12- 13℃ and 13- 14℃. Through our communication with the meteorological department, on the whole, the initial heating period this year is slightly higher than in previous years, and there is no hard condition for heating in advance.

In the face of the coming heating period, when can residents' homes warm up?

Starting today, it will gradually heat up this week. Except for a few projects that are still in the final stage, thermoelectric and geothermal energy of other energy sources have already started. In addition, the coal-fired boiler room also began to bake, and the boiler room that did not change to burn today also began to bake. After this year's burning modification project, the oven began to dry.

What are the preparations for debugging?

The first stage is the overhaul and maintenance of pipe network and equipment; The second stage is to prepare fuel, settle the cost of coal, water, electricity and gas, and replace parts; In the third stage, start the furnace. First of all, there is a lot of humidity in summer. Dry the furnace first, then add coal to ensure that it will not burn out, and then heat the water and send it out.

Starting from 1 65438+1October1,municipal and district heating inspection teams were set up to conduct on-site inspections of heating stations in the city, focusing on ignition heating, safety measures and various preparations for maintenance teams.

One or two thin gas sheets are always hot. What if it doesn't work after treatment?

From the reason, it depends on the thickness of the heating pipes connected in series. If they are too thin, there may be some design problems. The second is that there are not many impurities, dirty or not, and dirty water should be washed. Third, if it is a common phenomenon, it is necessary to appropriately increase the pressure of water. Specific analysis of the specific situation, specific solutions.

In some areas, heating is an old problem. It is not completely solved every year. Are there any corresponding measures?

Li Xiqing, deputy director of the Municipal Construction Committee, said that in recent years, we have been doing this work. Some are local circulation problems, and some are places where the old pipe network and facilities do not have pressure and temperature. We should improve the heating level through the transformation of the old pipe network. Every year, this city is rebuilding the old heating pipe network of 100 km. This year, 15 heating stations, 39 heating terminals and weak areas have been solved, especially some areas with frequent failures and dilapidated after hot water supply, such as 34 residential quarters such as Meteorology Beili in Hexi District and Li Xiyang in Nankai District, saving10900 square meters accordingly. For example, in 56 residential quarters 1 140000 square meters, such as Dongfeng Li in Hexi District and Feiyue Apartment in Hongqiao District, single-family heating and ring-dividing transformation are implemented to improve the thermal insulation performance of houses and make heating a safe project.

What should I do if I encounter heating problems?

In order to unblock the complaint channels of the masses, we actively interacted with platforms such as 8890 convenience service hotline and 123 19 urban construction hotline to solve the problems reflected by the masses in time. City, district heating office and heating unit open maintenance service telephone, 24 hours on duty, ready to accept the masses for repair, temperature measurement and other matters. At present, all heating units have been on duty and are on standby at any time, and the family maintenance and repair teams should be on standby around the clock.

In addition, tomorrow at 0: 30 am, the hotlines 1 1: 30, 123 19 will also hold special heating answering activities. At that time, the person in charge of the municipal heating office and the person in charge of the heating service of the energy group will go online together to answer the heating-related questions of public concern.
