First, the maintenance and renovation of heating equipment and facilities has basically ended. The total investment in the "three repairs" of heating in Shenyang is about 990 million yuan, an increase of 220 million yuan year-on-year. A total of 340 boilers have been repaired, 1,362 auxiliary machines have been updated, and 6,351 wells have been rebuilt. The organization carried out centralized rectification on 23 key areas with problems in the previous heating period, and comprehensively rectified the existing problems through measures such as overhauling boilers, reforming pipe networks and replacing equipment.
Second, key projects were fully completed. This year, Shenyang plans to transform the old heating pipe network by 210 kilometers, and actually completed the transformation of the pipe network by 226 kilometers, which is equivalent to three times that of previous years, and all the pipe networks that have been running for more than 30 years have been transformed. At present, the heating unit is testing the water, suppressing it, investigating the hidden dangers of the pipe network, and solving the problems immediately when they are found.
Shenyang plans to eliminate and transform 12 small civil coal-fired boilers, with a networking area of 3.39 million square meters. At present, 10 boilers have been networked, and 2 are in the process of finishing work, which is expected to be completed before October 20; Eleven clean heating projects are planned to be implemented, involving a heating area of 7.525 million square meters. At present, 8 projects have been completed and 3 projects are under construction, which are expected to be completed before October 20.
The third is the orderly advancement of heating and coal storage. This year, in view of the continuous high coal price, Shenyang Real Estate Bureau coordinated with the development and reform, public security and other departments, actively coordinated the coal production enterprises such as Tiefa to help the heating units implement coal sources, and the public security department took the initiative to apply for coal transportation permits for the heating units. Our bureau conducted daily statistics, daily scheduling, daily ranking and daily notification on the coal storage situation of the heating units, followed up and supervised the heating units with low coal storage rate, and organized the heating enterprises to dock with banks to solve the problem of enterprise funds. According to statistics, 66 heating units in the city plan to store 7.14 million tons of coal during the heating period this winter. At present, the contracted volume is 5.5 million tons, and the contracted rate is 77%; 4.141 million tons of coal has been stored, and the coal storage rate is 58%, which is the same as that of the same period last year. It is estimated that the signing rate before bolt opening can reach 100% and the coal storage rate can reach over 60%.
The fourth is to carry out trial operation. According to the requirements of the municipal government, Shenyang Real Estate Bureau has issued a notice, requiring all heating units in the city to do a good job in cold and hot trial operation. The heating system will be put into cold trial operation from October 20 to 24, and hot trial operation from October 25 to 31, to ensure that it meets the official heating standards on November 1. At the same time, according to the practice in previous years, each coal-fired heat source factory will implement sequential ignition of coal-fired heat sources and staggered peak start-up according to the requirements of the environmental protection department, so as to avoid centralized start-up affecting the atmospheric environmental quality.
The fifth is to standardize the work of charging services. Recently, Shenyang Real Estate Bureau organized a working conference on heating charging service, and issued the Notice on Further Standardizing Heating Charging Service, requiring heating units to strengthen service awareness, broaden payment channels and simplify charging procedures, and put forward clear requirements, and organize charging services for heating units, and supervise and guide heating units to standardize and orderly charge.
The sixth is to improve the supervision measures for heating operation. This year, Shenyang Real Estate Bureau continued to use the intelligent heating supervision platform to monitor the operation of water supply (return) temperature and pressure of heat source plants and heat exchange stations of various heating units and the room temperature of some users online. According to the operating parameters of the heating unit, command and dispatch the work of the heating unit at any time to ensure that the operating parameters reach the standard and the user’s room temperature reaches the standard.
Seventh, strengthen the emergency protection of heating. This year, Shenyang has set up 25 heating emergency teams, 221 large-scale emergency repair equipment such as electric welding machines and 6 standby mobile boilers. During the heating period, all emergency teams will be on standby for 24 hours, and they will arrive at the scene within 30 minutes in case of various unexpected accidents, and immediately carry out emergency repair work. At the same time, the Shenyang Municipal Government issued the Emergency Plan for Large-scale Heat Shutdown in Shenyang, and all districts, counties (cities) further strengthened the district-level winter heating emergency plan and emergency takeover plan.
This winter’s heating is about to begin. The cadres and workers on the heating front in Shenyang will do their best to do a good job in heating this winter with full enthusiasm and pragmatic style, and strive to hand in a satisfactory answer to the Shenyang Municipal Party Committee, the Municipal Government and the people of the whole city.
Answer a reporter’s question
Reporter: How to arrange the trial operation of heating this year?
Answer: Just now, a reporter friend mentioned the trial operation of heating. Let me explain the heating trial operation. This year, according to the work requirements of the municipal party committee and the municipal government, the heating trial operation will be carried out ahead of schedule. The heating system will be put into cold trial operation from October 20 to 24, and the heating system will be put into hot trial operation from October 25 to 31. The purpose is to find and solve the problems existing in the heating system in advance by carrying out the cold and hot trial operation of the heating system in advance, to ensure that the heating system reaches a safe and stable operation state, and to ensure that the heating standard for residents is officially opened on November 1.
The specific requirements of the heating trial operation are as follows: First, all heating units should conduct cold trial operation of the heating system from October 20 to 24, and all kinds of heating facilities should operate for not less than 48 hours, conduct comprehensive self-examination of the facilities, find problems and solve them in time. From October 25th to 31st, the heating system was put into hot trial operation, and the boiler room (heat exchange station), primary and secondary pipe networks should be gradually heated up, and the heating system should be adjusted. The indoor radiator of users should have a certain temperature to ensure balanced heating at the end of the heating system. Second, all heating units should do a good job in staffing to ensure an adequate number of maintenance personnel. During the trial operation of heating, it is necessary to completely solve the problems of indoor heating facilities blockage and wind resistance of residents, so as to alleviate the problems of residents’ application for repair and maintenance concentration in the early stage of heating, ensure the quality of maintenance services, and take effective measures to improve the satisfaction rate of residents’ heating demands. Third, all heating units should do a good job in window service, business service, maintenance service and complaint handling, further improve the level of heating service, and conscientiously implement the heating commitment system, so that users can report for repair immediately, and the timely rate of repair treatment should reach 100%. Fourth, all heating units must, in accordance with the requirements of the Municipal Bureau of Ecology and Environment, debug environmental protection facilities such as desulfurization, denitrification and dust removal at the same time of cold and hot trial operation, so as to ensure that environmental protection facilities can be used normally and discharge standards can be met.
Maybe everyone is a little unfamiliar with the technical terms of cold and hot commissioning. Simply put, the heating pipeline should have water and pressure during cold commissioning and water, pressure and temperature during hot commissioning. At the same time, our bureau organized district and county (city) real estate bureaus (housing and construction bureaus) to give full play to the role of the three-level guarantee responsibility system, and organized heating guarantee personnel to inspect the cold and hot trial operation of heating units in the region, and take timely measures to solve problems when found, so as to ensure the safe and stable operation of the heating system.
Reporter: At present, the city is about to carry out the trial operation of heating. What matters should residents pay attention to during this period? During the heating period, how do users reflect the heating problem?
Answer:
The first question: Matters needing attention during the trial operation of heating:
Summarized in one sentence: one stay, two check, three try, four secret, five prepare:
The first is to leave a telephone number, pay attention to the maintenance telephone number of the heat source factory and heat exchange station of the heating unit, and contact the repair service as soon as the heating leakage is found;
The second is to check the leakage and check whether there is leakage in the heating facilities of your own; After the trial operation, it is necessary to open the air valve in time to release the air in the pipeline.
The third is to try the valve, check whether the valve switch of the indoor heating system is flexible, and in case of emergency, you can close the valve first and then deal with it;
The fourth is strict sealing. Check the sealing conditions of your own doors and windows. If necessary, you can replace the sealing tape of the windows to improve the thermal insulation performance.
The fifth is to prepare a thermometer. It is recommended that users prepare a thermometer to observe the room temperature at any time. If the room temperature is not up to standard, they can report the situation to the heating unit at any time.
The second question: how do users reflect the heating problem?
-Users who encounter heating problems can directly call the public telephone of their heating units or heat source plants (heat exchange stations);
—— If the problem has not been solved or you are not satisfied with the treatment result of the heating unit, you can call the public telephone of the district heating management department or the citizen service hotline 12345-1-4 to make a complaint, and these departments will follow up and supervise the appeal at any time to ensure that the problems reflected by users are effectively solved.
