Commercial Natural Gas boiler Seller Vietnam

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."

Gas commercial boiler seller vietnam heat loss through the combustion of fuel gas boiler, will release some heat, which will supply part of the user, some will be recycled and part is inadvertently wasted. So these are wasted heat lost through the ways in which it (1) heat losses:? Flue gas exhaust gas boiler part of the heat into the atmosphere, causing the boiler heat losses, it is each boiler term heat loss Dazhong biggest one. The main factors influencing the heat loss is higher exhaust gas temperature and the amount of smoke exhaust gas temperature, the greater the amount of smoke, the greater the heat loss. Low exhaust gas temperature depends mainly on the number and operating conditions of the heating surface; the amount depends on how much leakage exhaust case and the furnace excess air, flue. (2) heat loss incomplete combustion gas: a part of the unburned combustible gas is discharged with the flue gas to heat loss caused by heat in the flue gas. The main factors affecting the incomplete combustion gas heat loss is the excess air and furnace structure. Excess air coefficient is too small, uneven air is mixed with fuel, easy to generate carbon monoxide and other combustible gases; excess air coefficient is too large, the furnace temperature is lowered, the combustible gas is not easy ignition and combustion. Furnace volume is too small, combustible gases in the furnace too late to enter the combustion flue gases caused by incomplete combustion heat loss. (3) heat loss: the furnace heat loss, frameworks, pipes, door opening caused by heat dissipation to the surroundings. Size depends on the heat loss factors of the size of the surface area of ​​the furnace gas steam boiler, heat insulating properties and thickness, the outside air temperature and the flow velocity. Electric heating reactor common external damage: an electrically heated reactor despite external corrosion has a high etching resistance against acid and alkali resistance, but our electrical heating by the heating apparatus is a kettle layer and an outer tire iron constituted. Such a medium is iron acids and bases are not corrosion-resistant. If we would have the production process if the reactor cover or screwed pipe joints without seal failure or leak acid tire iron reactor apparatus for electrically heating the outer corrosion. Corrosion support member 2. The reactor was heated electrically heated reactor during installation, support or other support member may be mounted directly on the floor, due to the long manufacturing operations on the floor may be deposited with corrosive media, so that for support our reactor electrically heated apparatus corrosion, resulting in the supporting force of each of the support produces a change resulting in a change in stress in the damage produced during heating layer. 3. The electrically heated reactor stress spout in the electrically heated reactor, when the steel of the pipe and the pipe joint, since the thermal deformation and the reaction was heated electrically heated autoclave vessel or duct stressed cold might damage the pipe.

The difference of fuel between Oil-fired Boiler and Gas-fired BoilerOil-fired commercial boiler seller vietnam refers to the fuel-fired boiler, including diesel oil, waste oil and other oil boilers. The overall arrangement of the oil-fired boiler is similar to that of the coal-fired boiler, except that the bottom of the furnace of the oil-fired boiler is mostly made into the bottom of the insulation furnace with a tilt to the back wall of 10 °~ 30 °, in order to obtain good combustion characteristics. In order to atomize fuel oil, there are two types of fuel burner nozzle: mechanical centrifugal injector and steam atomized Y type injector. The fuel of the oil-fired boiler is the fuel (such as diesel oil, kerosene, etc.). The fuel of the gas-fired boiler is gas (such as natural gas, city gas, biogas, etc.), depending on what fuel the boiler burns. The difference between a fuel-fired boiler and a gas-fired boiler is what kind of fuel burners are used to burn the gas-fired boilers, which are called gas-fired boilers, oil-fired boilers with fuel-fired burners, and oil-fired boilers called oil-fired boilers.

Boilers which are several general, in what is now the mainstream Why? 1, gas commercial boiler seller vietnam advantages: efficient, clean, environmentally friendly, without manual operation, only need to monitor, small footprint, no transportation fuel, no need to deal with soot, due to the combustion of natural gas free of impurities, without corrosion damage to the boiler and related accessories long boiler life, defined as 15 years, but basically long-term use. Is now mainstream boiler, natural gas is the environmental protection sector, the government vigorously promoted. Cons: You do not know how much that gas prices are calculated according to the calorific value and thermal efficiency, generally bituminous coal per ton of coal (according to 5500 kcal / kg) is approximately equal to 350 to 400 cubic meters of gas. Probably a little slightly more expensive than coal. (No transport, area, ash handling, labor, etc. into the calculation). 2, oil-fired boiler, advantages: substantially the same structure and properties of gas boilers. Disadvantages: higher cost of natural gas is 2 times the boiler, diesel transportation, storage more dangerous, accident-prone. And the domestic diesel supply is unstable, easily interrupted. 3, coal-fired boilers, the advantages: the economy. Disadvantages: 1, requires a lot of ash and coal yard area. 2, a boiler fireman for 4 to 8 people. 3, boiler room and coal yard is very dirty. 4, noise, emissions of dust, nuisance. 5, environmental protection departments often to check an inattentive, he was diagnosed with excessive emissions, maintenance shutdown, fine, very troublesome. 6, coal sulfur content are more severe corrosion of boiler, 10 to 15 years after the basic unusable. Summary: Due to high oil prices and supply unstable now, and now oil-fired boiler has been temporarily withdrawn from the market. Natural gas prices due to regional differences are very different, although you are not sure where the price of natural gas, but natural gas in most parts of the domestic coal is relatively expensive, (only in Sichuan, northwest of cheaper natural gas). Especially large industrial boilers, more fuel, the cost difference is more obvious. Coal-fired boilers to heavy air pollution, with the country on environmental issues more and more attention, more stringent emission requirements for coal-fired boilers, a lot of urban cities, has stopped the examination and approval procedures coal-fired boilers. It is recommended that, if your organization is not large tonnage production of boilers, installation of gas boilers or better, although with a little more than fuel costs, but in the actual operation of the process, you can save a lot of things, while saving area, the environment is clean.
