industrial gas fired water boiler for greenhouse
Gas hot industrial fired water boiler for greenhouse gas hot water boiler water quality standards and parameters of different capacities, in accordance with various operating conditions, the level of water treatment technologies and different long run, have different quality standard requirements. For details, see table below: This table is our current national standard "industrial boiler water quality" performance standards (GB1576-2008) mentioned. 1, the outlet for the rated steam pressure <2.5MPa, water as a medium, and a fixed soft drinks dual boiler hot water boiler, general use outside the boiler water treatment chemical, boiler water and feed water quality should meet the requirements of the table. 2, the rated evaporation <2t / h, and the rated steam pressure <1.0MPa gas hot water boiler of the boiler may also be employed and soft drinks dual dosing process in the boiler, the boiler must structure, corrosion and quality strengthen oversight, good dosing, sewage and cleaning, water quality should meet the requirements of the table. 3, pressure hot water boiler feed water for boiler water treatment should be carried out. 4, for hot water boilers and pressure hot water boiler rated power ≤4.2MW, you can also do the dosing process inside the boiler. 5, Feedwater should be outside the boiler water treatment chemical. 6, waste heat boiler water quality indicators and electric water boiler should be consistent with the type of required parameters with the boiler
Mill steam boilers to reduce pollution which method 1, leak checking and maintenance of protection: 2 mm steam leakage will cause energy losses of more than 10 tons of coal each year do? When you do not use it, you can turn it off to save energy. For water, steam and compressed air leak survey and routine maintenance, cost very little. 2, the non-contact cooling water in repeated use: Since the non-contact cooling water temperature and the quality is very good, it can be reused for desizing, scouring, rinsing and other processes. Three best source of cooling water is regenerated: sintering machine, a pre-link and compressor systems. The plant water recovery system may be installed, pipes, valves, storage tanks, and control systems. 3, reuse of steam condensate: textile mills require large amounts of saturated water vapor in the dyeing process, wherein a portion of the condensate is converted to its high temperature and purity. Water can be pumped back to the boiler to form a new steam. For those who buy steam from suppliers, or boiler is located away from the dyeing process, the condensate can be used as water washing or desizing. 4, pre-treated wastewater reuse Procedure collected bleaching, mercerizing machine, the water can be reused in other programs, there is no direct discharge of wastewater. 5, hot wash water is recovered from the hot gas in the dyeing process, large amounts of hot water are used to wash. Heat the washing water can be collected by the system plate heat exchanger to preheat the water to be sent to the next washing. 6, pre-screened coal enterprises should introduce screening spiral coal boiler technology to selection of raw materials. It is possible to improve the media tell the good, the bad quality of proportion, to avoid loss of small volumes of coal and coal calorific value. 7, maintaining steam traps traps can help maintain effective delivery of the steam plant. The valve is removed from the steam pipe and prevent further condensation water, so as to avoid heat loss and reduce fuel consumption. 8, pipe insulation pipes, valves and flanges, valves and flanges experience hot waste of resources, reducing efficiency. Steam delivery device insulated to prevent vapor loss is an inexpensive, energy-saving method of .9, the heat recovery boiler chimney smoke at a temperature of 360 deg.] C, and sometimes directly discharged into the atmosphere, there is no heat recovery. In fact, this heat can be used to preheat boiler water, steam or create a new steam system. 10, optimization of compressed air systems consume a large amount of compressed air in many parts of textile machines Mills. These instruments are prone to leakage, particularly in a threaded joint, rubber joints, valves, automatic regulator, the inflatable device and the old gasket. In addition, the use of compressed air pressure is usually based on the maximum pressure setting; reduce this pressure is feasible and would not have any negative impact manufacturing.
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."
