Han Weijie: how to avoid fog and haze in the heating season? The heating Department reduces the emission of pollutants according to the past years, in November 15th, Ji'nan will be formally heating. Winter is also the high season for haze days, and the environmental protection pressure of heating enterprises is very heavy. In order to ensure the reduction of pollution to the environment at the same time of heating, more stringent practices have been carried out in the areas of coal selection, environmental protection and wastewater treatment to reduce the emission of pollutants.
in October 31st, the red desulphurization tower is being built up at the Ji'nan light chemical heating plant at the bridge road. When the boiler burns, the smoke produced after the coal combustion will first enter the huge dust collector, leave some particles by the bag like dust collector, and then enter the desulphurization tower. During the desulphurization process of the 3 cycle of the desulphurization liquid, the sulfur dioxide and other harmful gases are absorbed, only the water vapor is allowed into the air. "Coal is controlled in a completely closed environment from the entry of heat plants to the end of combustion, resulting in waste residue and smoke and dust." Ji'nan Thermotics Inc responsible person said that the coal purchased this year is from Shaanxi and Yanzhou province's low sulfur coal. The sulfur content of coal is 0.6%, more stringent than the sulfur content of 0.8% last year, and the pollution of the environment is even smaller. "Every coal has been sampled and tested, and the coal with excess sulfur is resolutely returned, and it is not allowed to enter the boiler." In order to reduce the sulfur dioxide, dust and other pollutants produced by coal combustion, the two main heating enterprises in Ji'nan thermal power and Ji'nan thermoelectricity invested 240 million yuan, and 24 thermoelectric units and regional heating boilers were reformed for environmental protection. Among them, coal-fired boilers carry out "Shandong boiler air pollutant discharge standard", smoke and dust are 50 milligrams per cubic meter, and sulfur dioxide is 300 milligrams per cubic meter to meet the environmental emission requirements of 2020. Two questions: how does the price of coal prices fall? Heating price adjustment should be based on the cost of heating in the near future, some people doubt that "coal prices fall, but heating prices have not been down". In this regard, Ji'nan Municipal Public Bureau inspector Guo Sen said that in fact, the cost of heating is an important basis for the adjustment of heating prices. There are many factors affecting the cost of heating. In addition, the price of coal is an important factor. In addition, there are other operating costs, such as heating infrastructure construction, maintenance and hydropower, and the construction and operation of environmental protection facilities. Maintenance costs, personnel wages and welfare and so on.
Guo Sen said that in 2008, when the heating price was adjusted in Ji'nan, the average coal price was 777.21 yuan per ton of coal, and the cost of heating was 31.63 yuan per square meter. According to the principle of "part of the finance, the digested part of the enterprise, the sharing of a part of the user", and on the basis of the comprehensive consideration of the residents' bearing capacity and other factors, the final determination was to be settled. The heating price of the people is 26.7 yuan per square meter, which is 4.93 yuan per square meter compared with the actual heating cost.
724.82 yuan per ton of coal in 2009, 912.64 yuan per ton of coal in 2010, 942.07 yuan per ton of coal in 2011, 854.80 yuan per ton in 2011, 854.80 yuan per ton of coal in 2012, and 720.80 yuan per ton of coal per ton in 2013 and 2013 in 2013. Although the average price of heating coal has decreased by 134 yuan this year, it is only 56.41 yuan lower than the price of coal in 2008. Guo Sen said, according to the current situation, the price of heating coal has a downward trend, but the actual heating cost is still higher than the current heating price. In addition, in addition, in addition to the coal price factors, in recent years, energy saving and emission reduction have also been put into a large amount of funds. In order to ensure the discharge of the boiler, the heating enterprises have continued to increase the investment in environmental protection. Guo Sen said that in 2012 and 2013, the heating enterprises implemented the upgrading and transformation of thermal power units and district heating boilers' environmental protection facilities, with a total investment of about 310 million yuan. With the gradual improvement of environmental emission standards, the construction costs of environmental protection facilities such as desulphurization, denitrification and dust removal have exceeded the construction costs of the boilers. At the same time, the operation and maintenance costs of environmental protection equipment have been improved gradually, and the cost of heating is increased. In addition, with the increase of heating production costs and labor costs, it is predicted that heating enterprises will still be in deficit this year. Three questions: can the measurement fee be voluntary? As long as reasonable use is basically "more back" this year is the fourth year of the Ji'nan thermal measurement pilot, after the first 3 years of "more and less not to supplement" the thermal measurement pilot refund policy, this year's heat measurement refund policy or will be changed. And this variable also makes many residents no longer expect the heat metering pilot. Recently, in a district heat metering pilot's request, only a few households have accepted heat metering, and more residents prefer to heat by area.
originally, the notice on the charge of this district according to the heat measurement indicates that "the total amount of heat will be paid in accordance with the current standard. After the heating end, the metering heat is higher than the subscribers paid by the area no longer to pay the heat, and it is returned to the user within two months after the end of the difference in the area charged by the area." However, there is an additional sentence written on the back of the paragraph: "in the face of the new policy adjustment, we will carry out the new policy." At present, there are two ways to collect heating charges in Ji'nan: collection by area and collection by heat metering. The former charges the building area within the set, while the latter collects the heat fee according to the sum of the basic heat price and the measured heat price. Since 2010, the provincial city has implemented the pilot heat metering heating system. As of the heating season in 2012, a total of 90 million 640 thousand square meters of residential buildings in the province were implemented for heat metering and charging. This year, Ji'nan will formally implement heat metering heating, the implementation of heat metering area of about 3 million square meters.
heating enterprises related responsible person said that the city is now issued regulations must be implemented, because the heating season has not yet arrived, I do not know whether it will be adjusted. According to the relevant industry insiders, residents only take into account the "less fill", in fact, according to the pilot situation, as long as the reasonable use, basically can "more retreat". Four question: from the self tube station to "abandoning the pipe station", who is in charge of the management? The heating sector began to recover from 2003 to 2011, with documents stipulated that the heating units were only responsible for construction and management outside the red line of the project planning, so a large number of self-management stations were produced by the residential developers, property companies or property rights units. Management. In 2009, when there were more than 1000 self control stations in Ji'nan, some heating stations failed to meet the heating standards because of the cost savings, the reduction of heating standards or intermittent operation. And every heating season, complaints about self control stations are common.
in some old districts, because of the long running time of heating equipment and pipe network, the ownership of property rights is not managed and maintained for a long time, and some self pipe stations have become "abandoned pipe stations". Ji'nan's golden age district has been heating since 2004, and there have been no maintenance in the 8 heating season, of which 80% of the valves have been rusted and can not be used. "Last October, our company took over the yellow golden age self-management station, in the heating season of the year, found a total of 23 leaks, to the end of the operation, a total of 16893 tons of tap water, due to the large amount of water, resulting in two network supply and return water temperature decline, heating effect is very poor. Liu Honggang, deputy manager of Ji'nan thermal five company, told reporters that in more than 100 days, 25 repairs were made, and four or five times a day on average.
in order to improve the heating conditions in the golden age District, Ji'nan Thermotics Inc invested 3 million yuan to replace the two pipeline network, laying a pipeline of 2800 meters, and is expected to be completed by the end of this month.
since 2009, the heating Department in Ji'nan has started recycling the self control station. This year, Ji'nan thermal power combined with "steam to water" project, for the management of chaos, poor quality of heating, users complain more self tube station to focus on receiving. Raise funds for transformation, complete the receiving and transformation of 80 self pipe stations before heating this year, equipped with heating operators, and bring the self pipe station into the unified management of central heating to improve the quality of heat supply. Five questions: when does the eastern heating gap fill up? Some of the major heat source plants in the eastern part of the city are expected to come true in the future last March. Like Hengda famous city, in recent years, the pace of Ji'nan East Tuo has been accelerating, and many new developments have appeared in the eastern part of the city. Because the construction of heating pipe network and heat source plant is relatively slow, many new buildings in the eastern urban area are difficult to join central heating. The heating gap along the North Industrial North Road and the Wang's and Guo Dian section is up to 4 million square meters.
in October 24th, the reporter learned from the Ji'nan thermal department that in order to solve the heating problem of the east city, Ji'nan has implemented the industrial waste heat utilization project, heating the heating pipeline for the king and the industrial north road. In addition, the construction of the Tang Ye heat source plant will play a greater role in the future heating of the eastern new towns. It is understood that the Tang Ye heat source plant is located in the northwestern side of the Tang Ye section of the calendar District, planning the airport road to the East, south of the Jiaoji railway, covering an area of 5.665 hectares, and the construction scale of the project is built to install 7 70 MW high temperature hot water chain boilers. At present, the heating plant of Tang Ye has completed the bidding. In 2014, the heating period will have the conditions of external heating, and the eastern area can add 13 million 810 thousand square meters of heating area.
the Ji'nan municipal government also has long-term plans to supply high temperature water and heat sources from the Zhangqiu power plant to the eastern part of Ji'nan. In order to improve the heating quality of the east city, several large heat source plants in the eastern city of Ji'nan are expected to join together in the future. One heat source factory has problems, and the heat source of other heat source plants will quickly solve the problem.
