Recently, the National Energy Board, the Department of Ecology Environment issued "on the issuance of 2018, the provinces (autonomous regions and municipalities) of coal ultra-low emissions and energy-saving targets and tasks" (the "Notice"), called on all localities continued to do over coal low-emission and energy-saving, and promote the development of clean and efficient coal. Ultra-low emissions and to promote energy-saving work in the country has been more than two years, has been established to complete the task of transformation in the eastern provinces, the transformation of the focus shifted to the central and western regions, while the transformation of scope as technology advances and the increasing demand for policy gradually extended.
Under the "notice" requirement, this year nationwide, ultra-low emissions coal power reform objectives and tasks a total of 48.68 million kilowatts, energy-saving goal is to reach 53.905 million kilowatts. In 2016, the capacity of the units involved in the transformation of two to 254.36 million kilowatts, respectively, and 189.4 million kilowatts, good reform bear fruit.
President of the State Power Environmental Protection Research Institute Zhu France and China, said: "By the end of last year, a nationwide ultra-low emissions transformation target task completion rate has reached 71%," ultra-low emissions coal and transformation better, the eastern region has been basically completed, part central provinces ahead of the completion of the task of transformation.
In 2015, the former Ministry of Environmental Protection, the National Development and Reform Commission, the National Energy Board issued "the full implementation of ultra-low emissions and energy-saving programs of work-fired power plant", requires the completion of the eastern part of the overall transformation of ultra-low emissions before the end of 2017, the central region and strive in 2018 years basically completed, the completion of the western region in 2020. "2018 provinces (autonomous regions and municipalities) of coal ultra-low emissions and energy-saving task summary table" (hereinafter referred to as "transformation task list") shows that the eastern provinces have been basically completed the transformation of ultra-low emissions, not published this year transformation capacity unit task. But it is located in the Yangtze River Delta, Jiangsu Province, still issued 1.4 million kilowatts ultra-low emissions and energy-saving renovation target of 900,000 kilowatts.
Zhu France and China, said, "in accordance with the requirements of 2015, Jiangsu has completed the ultra-low emissions and energy-saving target in 2017. However, the new policy will be more units into the transformation range, Jiangsu this year, there is still the task of transformation. In June, the State Council issued a "winning blue sky battle three-year action plan" (hereinafter referred to as "three-year action plan"), required by the end of 2020, more than 65 tons of steam key areas of coal-fired boilers have completed ultra-low emissions and energy-saving. "
It is understood that "three-year action plan" prior to the implementation of energy-saving and environmental protection requirements only for the reconstruction of more than 300,000 kilowatts of conventional units, more than 100,000 kilowatts of power plant owned units. "According to the existing requirements, including Beijing and Tianjin and the surrounding areas, the Yangtze River Delta region and Fenwei plains, including the key areas, more than 65 tons of steam boilers are also included in the scope of the transformation will involve part of 100,000 kilowatts or less captive power plant units and industrial boilers. "Zhu France and China, said," "three-year action plan" in addition to the deadline of 2020, does not provide a specific timetable for the task. Next, the key areas are the provinces in accordance with the requirements of more units, boiler transformation. "
"Task of transformation" table displays, ultra-low emissions transformation capacity this year, mainly in the western region of Inner Mongolia, Shaanxi, Gansu, Xinjiang and so on. In the trend of ultra-low emissions overall speed of the transformation, central Shanxi, Anhui, Henan and other provinces in the region have been completed ahead of the transformation target ultra-low emissions, but energy-saving task still more arduous. Among them, Henan Province this year, energy-saving target capacity of 10.8 million kilowatts, Hunan has reached 9.995 million kilowatts.
Since the ultra-low emission transformation involves the emission of pollutants and other environmental problems, caused by the high social concern. In contrast, concern about energy-saving electric power mainly from the enterprises themselves. Zhu France and China, told reporters, on the one hand is the national energy saving policy requirements, on the other hand also in line with the needs of enterprises to reduce their own costs. At present coal prices continued to run high, coal companies operating pressure, reduce production costs even more urgent demand.
In 2014, the National Development and Reform Commission, the former Ministry of Environmental Protection, the National Energy Board issued "coal upgrading and transformation of energy saving action plan (2014-2020 years)", for energy-saving technology roadmap active coal-fired power units were enumerated, involving the master each link auxiliary equipment, environmental protection equipment and a total of 20 reform measures, in addition to "subcritical unit transformed into ultra (ultra) supercritical units", the rest of the technology have already matured.
In recent years, along with tighter environmental requirements, provide renovation and operation and maintenance services to the rapid development of environmental protection industry. In particular third-party environmental companies, with technical, cost and other advantages, occupy a certain share of power generation enterprise environmental transformation market. But a power industry experts said, is very difficult third-party independent companies to enter the field of environmental protection energy-saving power plant.
"Ultra-low emission increase in the transformation of the original system is new equipment, energy-saving and optimized for major transformation of existing equipment, and boiler plant, steam turbine plant than environmental protection enterprises to understand their own devices." The expert said, "Not only that as systems engineering, energy-efficient coal-fired units involved in the whole process of production, and plant operation economy, is closely related to security, not easily open to third-party companies. third-party companies to enter the energy-saving environmental protection than to enter the market face greater pressure."
What forms of chemical plant indi200kg industrial boiler temperature inspection there? What forms of chemical plant boiler inspection there? Or organic heat boiler uses water as the medium pressure vessel was heated by a flame or electric heating, and multi-output heat to steam, hot water forms, during operation of boiler, the furnace member at a high temperature and pressure, or external temperature flame radiation, may occur wear, corrosion, distortion, scaling, and other defects over-burning, ash plugging may also occur, slagging phenomenon. More serious will lead to burst pipes or explosion and other accidents, if not timely detection to eliminate them, will eventually lead to loss of life, damage to equipment, to bring social unrest, cause losses to the state and enterprises. Check the boiler is a boiler to minimize the risk of the task. Boiler Inspection generally divided into boilers and boiler Supervision, Inspection and periodic inspection, the former is an integral part of the normal operation of the boiler in a test, divided into internal and external inspection test boiler boiler; the latter is mainly for boiler installation, alteration, major repairs an extremely important test carried out. 1, chemical plant boiler regularly inspect boilers periodic inspection refers to the periodic inspection of boiler inspection rules for safety and energy savings boilers carried out according to regular inspection prolong the service life of the boiler, including external inspection running under the boiler, boiler stop internal inspection and hydrostatic test under the operational state. External inspection cycle once a year; internal inspection period is every two years; the boiler because of structural reasons can not carry on in the inspection, hydrostatic test should be carried out, for the period of 3 years. Including internal content inspection for cracks, cracks, corrosion, scaling and other defects on the drum, boiler shell, superheater, airway pressure receiving member and the like; the same shall be the time when the problem occurs in the last test specimen methods for review. External inspection tests generally include the following elements: operation of the boiler external environment and load-bearing device, an external boiler piping, safety accessories and safety devices, auxiliary equipment. For external examination of organic heat carrier boiler, acidity should review inspection reports and records, kinematic viscosity, carbon residue, water and other indicators of compliance with national standards, to check its compliance with safety devices regularly boiler inspection rules. 2, Boiler Inspection Boiler Inspection supervision include chemical manufacturing supervision and inspection of boiler and boiler installation, alteration and major repair of supervision and inspection. Supervision and inspection methods commonly used data review, physical inspection and on-site supervision methods. When data review should be strictly regulated in accordance with the pot; when the inspection site monitoring, supervisory inspector should be carried out in accordance with the relevant system standards, to comply with the relevant safety specifications; when physical examination, in general, checks manner. Supervision and inspection of the boiler by the degree of impact on the safety performance of the boiler can be divided into A, B, C categories, followed by a significant impact, greater impact, the general impact. Former chemical plant boiler supervision and inspection, the following should be inspected units do a good job, ready to license within the validity period (but without permission or license application has been accepted); develop plans to submit construction plans or production supervisory agency; provided the necessary supervisory inspection work conditions.
