Commercial 2t Natural Gas boiler Factory Price Cambodia

2. Environmental policy is required for commercial 2t boiler factory price cambodia emissions. Coal-fired boilers for waste pollution and energy of the atmosphere is amazing. Many cities have been expressly prohibited by the new economic development zone on the coal-fired boiler, while the use of gas, oil, electric central heating boiler or cogeneration.

3. The boiler is the initial investment, including the boiler unit, ancillary equipment, construction investment and other related costs.

Low nitrogen commercial 2t boiler factory price cambodia and classification of meaning: In recent years, the state vigorously promote clean air plan, Yajian coal. Whether the use of coal-fired central heating boilers, and rural small coal stove for cooking and heating, are gradually being clean energy alternatives under the relevant policy. Thus, in recent years, sulfur dioxide, dust content in the atmosphere continues to decline. But it is worth noting that more and more use of natural gas, also caused a certain amount of nitrogen oxide pollution. Use low nitrogen boiler of the environmental benefits of very large.

Coal-fired commercial 2t boiler factory price cambodias to gas boilers benefits and precautions With the rapid development of national energy-saving environmental protection, the traditional coal-fired boiler can not meet the needs of the times. Therefore, the coal-fired boiler biomass boiler or gas boiler has become in many boiler user's choice. Before the transformation, to understand the difference between .1 and gas boiler fired boiler. Circulating fluidized bed combustion boiler fired by coal crushing device fluidized combustion process, the coal by crushing device percutaneously into the bunker through a the spreading coal coal injecting air into the furnace; circulating ash by heating, fluidized combustion process. When the coal into a gas fuel is injected directly into the combustor for combustion. 2. Combustion of Coal is mainly composed of C, H, O, N, S, ash and moisture and other elements. Generated when coal SO2, SO3, NOx ash and moisture, and SO2, SO3, NOx from flue gas emitted into the atmosphere, pollute the environment and cause harm to humans. The main components of the exhaust gas and coke are CO and H2. The main produce CO2 and H2 post-combustion, much lower than coal-fired boiler SO2, SO3 and NOX emissions. 3. Ventilation pressurized combustion coal combustion boiler used in a combustion mode. The bottom of the combustion process through the induced draft fan with fan and completed. In the combustion of coal, it requires a lot of air. Gas under a slight positive pressure in the boiler or burner slightly negative pressure, which requires less airflow. Burner air may be pre-mixed with natural gas. 4. coal boiler control reasons, material thickness, amount of wind, the wind volume, wind and other than coal, coal-fired boiler is difficult to automatically adjust the operating parameters of the boiler according to the load. However, fewer factors gas boiler, the burner valve can be adjusted according to the size of the load, easy to implement automatic control. Coal-fired boiler to a gas boiler Notes: Main results are as follows: (1) small boiler, the coal-fired boiler to a gas boiler, i.e. the negative pressure of combustion from the original to the current combustion slight positive pressure, and must pay attention to the furnace wall structure sealing problems. Closely related (2) selection and arrangement of the burner and furnace, the degree of filling of the flame in the furnace is preferably not formed dead air, to avoid the interference of adjacent flame burners, to avoid interference from adjacent burner flame. Unburned gas - air mixture should not be in contact with a heated surface, in order to avoid incomplete combustion. Gas combustion. Gas burner arrangement disposed conduit and ducts should be considered reasonable gas pipe and duct arrangement, ease of operation, inspection and maintenance. (3) the transformation of coal-fired boilers is mechanized layered gas boiler should be removed before the arch and the arch, and the bottom heating surface increases, in place of the grate, the grate to prevent overheating. Gas Velocity (4) on heat transfer surface of the fly ash is not restricted abrasion conditions, convection heating surface heat transfer coefficient is increased, increasing the pressure in the boiler where H is unduly increased. Boiler erosion surface. At this time, the capacity of the boiler should be noted that the steam separator to ensure the quality of the steam.

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."
