  • Detail

Taiyuan's coal-fired pollution control has entered a "peak moment". By the end of October, the urban fuel coal will be "cleared"

according to China Environment News, the coal-fired heating boilers in Taiyuan, Shanxi Province, will be "cleared", 134000 households will be "changed from coal to electricity" and "from coal to gas" for heating this winter, 36 urban villages and 36 shanty towns will be demolished and reconstructed as a whole, and the coal-fired boilers in heat source plants such as Jinyuan, Xiaodian and Dongshan will be replaced by clean energy, The annual coal consumption will be reduced by 2million tons

it is only more than two months before the winter heating season. At present, Taiyuan's coal-fired pollution control has entered the "moment when the list of qualified enterprises is released at the peak". All departments and units at all levels are solidly promoting the coal-fired pollution control work, striving to repay more old accounts and resolutely not owe new accounts

symptoms coal burning pollution is prominent during the heating period

for a long time, Taiyuan, as a resource-based city, has a coal-based energy structure and a deep-rooted "coal thinking". In terms of air quality, coal smoke pollution is obvious, especially in the winter heating period, tens of thousands of small coal-fired heating boilers in urban villages "make fire every household, and smoke every household", and low-level non-point source pollution is particularly prominent

it is understood that in 2016, there were 26 days of heavy pollution above grade 5 in Taiyuan, all of which were concentrated in the heating period in winter. The comprehensive pollution index of air quality in heating period is 1.6 times that in non heating period, and the average concentrations of SO2, PM10 and PM 2.5 are 3.9 times, 1.5 times and 1.9 times that in non heating period respectively

it can be seen that the coal-fired pollution during the heating period in winter has become one of the important factors restricting the further improvement of air quality in Taiyuan

"to make the people breathe cleaner air, we must overcome the barrier of coal-fired pollution in winter heating period, vigorously reduce the amount of coal-fired in heating period, and seek a breakthrough in changing the fuel structure and alternative ways of energy structure." Dou Lifen, director of Taiyuan Environmental Protection Bureau, said

action by the end of October, the urban area will be built into a "no coal zone"

coal pollution control is a complex systematic project, which requires the concerted efforts of the whole city. In order to strengthen the implementation, Taiyuan has established a leading group for the clean treatment of loose coal, with luoqingyu, Secretary of the municipal Party committee, as the group leader and gengyanbo, mayor, as the first deputy group leader, to be responsible for the formulation of major policies and measures, the organization and coordination of major issues, and the assessment and accountability. At the same time, each county (city, district) is required to establish a headquarters for clean control of bulk coal, with the Secretary of the county (city, district) committee as the first commander in chief and the head of the county (city, district) as the commander in chief. The city has established a working mechanism for coordination and guidance of relevant departments directly under the city and organization and promotion of local governments to implement the clean control of bulk coal

Songli, director of the regional division of Taiyuan Environmental Protection Bureau, said that the goal of Taiyuan's bulk coal control in 2017 was to build a "no coal zone" in the urban area by the end of October, and to achieve "zero" of fuel coal, all of which were replaced by clean energy within the urban area, including domestic coal, coal for agricultural production, coal for commercial activities, coal for enterprises and institutions, and coal for industrial enterprises (except Taiyuan Iron and Steel Co., Ltd., second power plant and reserved heat source plant), The replacement rate is 100%

for this reason, Taiyuan clearly requires that the clean heating renovation projects of "coal to electricity" and "coal to gas" for 134000 households in 56 urban villages and 269 rural areas be completed by October 10. By the end of September, 471 existing coal-fired heating boilers in the urban area and 18 decentralized coal-fired heating boilers in the county urban construction zone will be "cleared", 21 coal-fired boilers in the five heat source plants that undertake centralized and continuous heating and 149 coal-fired boilers that often give full play to the value of plastics in the "three counties and one city" will be replaced by clean energy. During the year, 36 urban villages and 36 shanty towns were demolished and reconstructed. At the same time, for coal-fired boilers outside the built-up areas of "three counties and one city" that cannot be replaced by centralized heating and clean energy for the time being, strict coal-fired control and upgrading of boiler flue gas treatment facilities will be implemented to ensure that the special limit requirements for air pollutant emissions are met by the end of September

in order to prevent the re burning of bulk coal, Taiyuan has designated all the urban areas (the six urban areas, the comprehensive reform demonstration area, and the stainless steel Park) as "no coal zones", and implemented the prohibition, embargo, and prohibition of bulk coal. At the same time, it is required to build a coal-free village. All rural areas that have completed the clean heating transformation will resolutely implement the "one cleaning and two dismantling", that is, clearing and storing coal, dismantling boilers (stoves) and coal stoves, strictly prohibiting the loose burning of raw coal in various forms, so as to ensure the safety of gas use and the improvement of atmospheric environment quality

guarantee the introduction of subsidy policies to benefit the people

in order to ensure that the tasks of coal pollution control this year are completed on schedule, Taiyuan city introduced a series of subsidy policies to benefit the people in late July

if the "coal to electricity" heating transformation is implemented in the rural areas of the city, including the laminated material fiber-reinforced thermosetting and thermoplastic composite material areas, if the air source heat pump and regenerative electric heating are used for heating, the equipment purchase cost shall not exceed 27000 yuan and 14000 yuan respectively by the two-level financial subsidies of the urban area; In each heating period, the urban governments at two levels will give a maximum subsidy of no more than 2400 yuan per household to the farmers who have completed the "coal to electricity" project

for the implementation of "coal to gas" or "coal to LNG point heating transformation" in urban and rural areas, in principle, the urban two-level finance is limited to subsidizing only one 26KW and below gas wall mounted boiler per household, and the urban two-level government will give a gas price subsidy of no more than 2400 yuan per household in each heating season

for users who implement clean energy substitution for coal-fired heating boilers, the municipal finance will, in principle, subsidize the construction cost of 30 yuan/square meter at one time

at present, coal pollution control has been in full swing in Taiyuan, and various projects have entered the countdown. In addition, the departments of supervision, audit and finance have gone deep into the grass-roots level to comprehensively carry out follow-up supervision and follow-up effectiveness, so as to ensure the compliance of the operation of pollution control projects and the safe and efficient use of funds

if the task is not completed, it will be "one vote veto"

there are still two and a half months before the heating period in winter. However, Taiyuan coal-fired pollution control has entered a "peak moment", and all levels, departments and units have been working at full capacity, reversing the construction period, and making every effort to sprint to the target task

Xiaodian heat source plant and Dongshan heat source plant are one of the heat source plants in the urban area of Taiyuan, undertaking the winter heating tasks of 5million square meters and 3million square meters respectively. It can be seen from Xiaodian heat source plant that the original five 280 ton coal-fired boilers have been demolished, and two 60 meter high chimneys are being demolished. In addition, three newly purchased 348 ton gas-fired boilers are ready for installation

"before heating this winter, the two heat source plants will change from coal-fired heating to gas-fired heating. The coal storage yard in the heat source plant will be replaced by gas-fired boilers, and the heating method will be cleaner and more environmentally friendly." Lishuangkui, deputy general manager of Taiyuan thermal power company, said that according to preliminary calculation, after "changing coal to gas", the two heat source plants can reduce coal consumption by 120000 tons per year, and at the same time reduce the annual emissions of 127.33 tons of sulfur dioxide, 149.91 tons of nitrogen oxides and 387.34 tons of smoke and dust

it is learned that at present, the scattered coal-fired heating boilers of 20 tons or less and all the coal-fired boilers in long-term operation in Taiyuan have been "cleared", and 90% of the tasks have been completed. The annual emission reduction of sulfur dioxide is 8000 tons, nitrogen oxide 7600 tons and smoke and dust 5000 tons; 85.4% of the "scattered pollution" enterprises have been shut down and banned; According to the "one policy for one household" transformation scheme, the power supply department and the gas company are effectively connecting with the residential households implementing the "coal to electricity" and "coal to gas" to ensure that the measures, inputs and implementation are in place

Che Jianhua, vice mayor of Taiyuan in charge of environmental protection, said that he would strengthen the continuous supervision and inspection of clean heating operation, strictly prohibit and severely crack down on the sale of raw coal to clean heating areas. For the counties, districts and towns that have completed the "coal to electricity" and "coal to gas", it is necessary to innovate the coal management and control mechanism, focus on the coal sales and supply side, cancel the bulk coal sales points, and prohibit the inflow of bulk coal. At the same time, the control of bulk coal pollution is included in the assessment scope as an important matter to improve the environmental quality of provincial cities, and the assessment of dispatching is strengthened. If the task cannot be completed, the "one vote veto" is implemented
