3000kg natural gas boiler
Qinhuangdao City Funing District Branch of Ecological Environment Agency organized the key enterprises responsible person within the jurisdiction of the 3000kg boiler demolition, renovation work will hold a special schedule. The meeting stressed the need to vigorously promote coal-fired, gas-fired boiler demolition, renovation work progress, continued to improve ambient air quality.
At the meeting, staff of the Office of atmospheric area of the current coal-fired, gas-fired boiler demolition, renovation progress has been informed. Up to now, boiler demolition and reconstruction of the region involved all disabled.
First, Funing District compressed air quality improvement increasingly smaller space, air pollution prevention and control situation is very serious, involving various enterprises must attach great importance to effectively assume responsibility for environmental protection.
Second, the coal-fired boiler in accordance with the "water power, chimney down, shifting the body" standard transformation and low nitrogen oxides emissions analyzer mounted nitrogen gas boiler work requirements, make sure the end of this completed, the embodiment late cut-off regulation.
Third, the Bureau of atmospheric sciences, environmental law enforcement unit to further strengthen law enforcement and inspection and supervision, the monitoring center to provide scientific data monitoring, to crack down on environmental violations, it is important to ensure that coal-fired, gas-fired boiler demolition, renovation work is completed on time.
What is "green 3000kg boiler" "boiler environmental protection" is a more general concept, a broad sense, refers to the boiler exhaust emissions, waste emissions and other environmental requirements of the load does not refer to a certain kind of single boiler. According to China's latest introduction of emission standards of air pollutants in some areas, Beijing, Zhengzhou, Xi'an and other cities of nitrogen oxide emissions have been reduced to the minimum standard of 30 mg / cubic meter. For fuel gas boiler, the combustion by the use of advanced technology or environmental burner configuration to achieve NOx emissions below 30 mg / m, belong to "green boiler." Electric boiler not to detail that the use of electricity as power and energy, waste no exhaust emissions, but are "environmentally friendly boiler" type. Environmental protection boiler they use FGR, premix combustion technology and other advanced reprocessing of flue gas, the flue gas heat reuse, reduce exhaust gas temperature. Can improve the thermal efficiency of the boiler, and reduce harmful substances in flue gas emissions, energy conservation and environmental protection to achieve social, economic double benefit. Fast boiler cleaning has many years of experience in manufacture and sale of boilers, and has developed a number of patented technology, production of boilers meet the most stringent air pollution emission standards in China. If you have to "green boiler 'needs or problems, can contact me directly, professional and technical engineers in real time to answer your questions.
Chemical prevent high temperature corrosion of 3000kg boiler waterwall boiler chemical improvements to prevent high temperature corrosion improvements waterwall 1, using an anti-art windshear main principle is offset by a spray angle of air flow injection port, and the original jet forming a motion , the opposite direction of rotation, in tangentially running smaller diameter, due to the opposite running direction of the initial movement of the main gas flow direction of the gas flow in the furnace after the anti-wind shear, the pulverized coal injected hindered high-temperature air upstream of the primary air flow and the time, the pulverized coal injection speed is reduced rapidly, enhancing coal dead time in high temperature zone, to enhance the combustion efficiency of pulverized coal. By using an anti-wind shear can effectively prevent high temperature corrosion phenomena, and can enhance the ability to stabilize combustion in the boiler furnace, reduced coke boiler case, as shown in FIG. 2, using the technology of Side by side wind technology is mainly on the high temperature zone waterwall corrosion or high temperature corrosion installed upstream of the injection port area, and ejecting the air in the furnace boiler. Technology is mainly employed side air can be controlled in the high-temperature reducing gas corrosion area, enhanced oxygen content in a local range. 3, to improve the control operation to take excess air coefficient increases, a plurality of coal mills is not put into operation at the same time, reduce the coal particle size, increase the air preheater ash fouling preventing plugging of equipment and operation control systems such as high temperature measures to prevent High temperature corrosion phenomena.
5. The local site environment protection standard
For natural gas fired boiler, if it has requirements about NOx emission , for biomass boiler , the particular emission is very important , if local is strict with the dust emission ,as 30mg/nm3 ,maybe the boiler system will need bag filter , the price will enlarge .
