101 percent vacuum hot water boiler

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."

Operation of the 101 percent vacuum hot water boiler operation is very simple vacuum hot water boiler is very simple, bank up a fire, dust, water, ignition thanks to this step, when the bank up a fire is the first cleaning, the ash cleaned and then fill the coal bucket to shut the door on coal. Economic and environmentally friendly vacuum hot water boiler is in line with the needs of social development, therefore, vacuum hot water boiler is also welcomed by the people, and its usage is very large, their own strengths vacuum hot water boiler determines its space development huge. Automatic heating, hot water boiler vacuum meter is automatically displayed temperature and pressure, the secondary vacuum hot water boiler 24 hours can be a stoker, a hot water boiler so that the vacuum can maintain a constant temperature all day, so the use of it will be more convenient vacuum hot water boiler thermal efficiency is very high, can quickly heat up, and there is no dust, of course, and there is no smoke, so that the surrounding environment will not cause any harm to make . Vacuum hot water boiler operation is very simple, he has a very novel appearance, this novel shape can play a decorative role, then there is the structure of the vacuum hot water boiler is also very unique.

Maintenance and corrosion protection of a hot water boiler, water supply oxygen due to some timely accumulation of dissolved oxygen corrosion of hot water boiler will result in increased water supply process, therefore, at the same time equipped with the appropriate oxygen equipment should be better the efforts to control the entire water supply. The oxygen present embodiment mainly sodium sulfite chemical reaction oxygen, this effective method of oxygen can fully reduce the overall corrosion to metal. Meanwhile, some capacity is relatively increased water boiler, may also be employed in high vacuum or low oxygen equipment, a reasonable way is to use hot water boiler air evacuated, forming a gas hot water boiler pressure less than atmospheric pressure will reduce air leakage phenomenon occurs, play a good maintenance effect. Second, strict control of the pH of the boiler water in accordance with the regulations of the country, the pH of the boiler water is controlled within a predetermined range, this can be well protected by film formation, avoiding corrosion of the metal walls of the hot water boiler . Case of pH value rises or falls appear outside the furnace, to take timely measures to maintain, when the entire index is below 10, you can put some alkaline agents on the hot boiler to an appropriate increase to a normal pH, can also be run by using trisodium phosphate and sodium hydroxide to adjust the dose to accurately control the pH of the water throughout the furnace, so that, to maintain good control effect, helps to reduce boiler corrosion, build clean and efficient mode. Third, strengthen the maintenance of boilers disabled during shutdown, such protective measures are not taken, the boiler water and steam system of the metal surface corrosion is dissolved oxygen, since the boiler generated during operation is an alkylene iron corrosion products compounds, can become disabled at the time of high iron oxide compound, which makes corrosion process is repeated down the line. And therefore must take appropriate protective measures during boiler shutdown is disabled, avoid and mitigate corrosion of the boiler. Maintenance of two ways: First, dry maintenance, and second, wet maintenance Wet maintenance Currently we have taken as follows: (1) the pot of water after shutdown exhausted, remove scale, impurities and soot. (2) off (or blocked with the blind plate) each of the ducts of valves connected to the boiler. (3) The demineralized water injected into the boiler to a minimum level, with special preparation of a good basic corrosion pump liquid injected into the boiler. (4) When all the injection liquid corrosion boilers, boiler water supply valve is turned on, the boiler filled with demineralised water until the pot of water drained out from the valve, closing the valve and emptying the water supply valve. (5) Open special boiler water circulation pump, so that everywhere in the boiler alkaline solution concentration uniform corrosion. (6) During the maintenance, you should always do external examination, and regularly testing pot with water, and liquid or alkalinity level drops, should identify the reasons for timely processing and additional liquid. (7) periodically open water circulation pump, the liquid concentration consistent throughout. (8) during the wet winter maintenance of the boiler, the boiler temperature must be kept above 5 ℃ and do the following. a. during the entire maintenance, raw Microflame oven regularly in order to maintain the outer surface of the heated drying. b. To start a regular water circulation pump, the concentration of the solution is consistent throughout. c. also regularly take the solution testing, if the alkalinity is reduced, should be supplemented. d. Winter freezing measures to be taken. Conclusion of people using the hot water boiler in the current society continues to increase, for the maintenance and repair of hot water boiler has been people's attention, but at a certain point of view, people are now plagued by the boiler normal use of the main factors that boiler corrosion situation occurs, this corrosion occurs not only will make the life of the boiler there is a certain decrease in the safety of the boiler will make a corresponding reduction, so this needs to boiler rusting conduct a comprehensive analysis, and in accordance with the results of the analysis put forward countermeasures boiler fundamental Rusty effective solution, so that the development of China's water boiler to get some protection.
