How to put ordinary gas high quality fired boiler boiler emissions become low nitrogen boiler is an important cause of air pollution in order to reduce pollution of the boiler, in the country minus the cancellation of coal coal have done a lot of work, which significantly reduces the solid boiler soot emissions and sulfur dioxide emissions of polluting gases. But only coal-fired boilers will be replaced by gas-fired boilers, boiler did not reduce emissions of nitrogen oxides, so the boiler with a new task becomes low nitrogen boiler boiler also became current. In the end what is low nitrogen boiler? In many areas, there is no mandatory use of low nitrogen boiler regulations, and in Beijing, mandatory use of low nitrogen requirements of the boiler has been formally introduced in April 1 this year, the existing boiler will perform the following 80mg standard, the new boiler will perform the following criteria 30mg, 80mg and standard criteria will gradually be replaced by 30mg of the boiler, and therefore in Beijing, boiler NOx emissions less than 30mg in order to become a low-nitrogen boiler. In Henan, the new gas-fired boiler will also perform the following criteria 30mg of nitrogen oxides, we can safely predict that the future low nitrogen boiler will be large-scale promotion. At this stage, a lot of nitrogen oxide emissions from gas-fired boiler in 150mg or less, which is far unable to meet the standard low-nitrogen boiler. Ordinary means into a low nitrogen gas boiler with a boiler or low nitrogen transformation replace the original boiler is condensed into nitrogen oxides emissions below 30mg (formula) boiler. Nitrogen mainly low boiler transformation replace Burner, mainly in the following ways: 1, flue gas recirculation transformation (Ultra Low NOx) is the use of combustion air head, the part of the combustion fumes sucked back into burner, and combustion air mixture. Since the flue gas recirculation, the combustion fumes a large heat capacity, the combustion temperature is lowered, the NOx reduction. Another recirculation burner itself is directly recycled into the part of the fumes inside the burner and to the combustion process, the burner has such a suppression effect of nitric oxide and the double energy. 2, the premix burner (combustion surface) technology premix gas burner, the gas and air are thoroughly pre-mixed prior to entering the combustion chamber, so that more complete combustion, improve the combustion efficiency and reduce harmful emissions, but also can reduce the space requirements of the combustion chamber, is currently the most advanced of a gas combustion technology. Due to the low NOx combustion boiler renovation and diverse, sophisticated technology, in order to ensure the smooth implementation of the transformation, effectively preventing security risks, prevent accidents, analysis and appraisal by experts, comprehensive security, environmental factors, Beijing and the Beijing Municipal Environmental Quality and Technical Supervision protection Bureau jointly issued a notice :( a) for 7.0mw (evaporation 10t / h) or more in the boiler is not recommended transformation of the way premixed combustion. (B) to the central back-fired boilers, the transformation is not recommended way to replace the burner. (C) For boilers, does not recommend the use of direct transformation of the way the transformation of the burner. Therefore, a low nitrogen transformation process boiler, more often, is a direct replacement for the original gas boiler low nitrogen boiler.
The product of this project is the CBM wns series oil and gas steam boiler with a boiler capacity of 3 tons. The boiler is used in a building material factory in Russia to provide steam for concrete production.
Currently, this system through continuous innovation and improvement, has launched a cloud service 3.0 system, you can take advantage of fast, accurate high quality fired boiler data collation and analysis of Things technology, and to help customers understand the use of the boiler through the data to ensure safe and effective boiler run. As of the current track, the number of systems online boilers 4600 units, enterprises and institutions to use fast boiler feedback to us, with this system uses a boiler more peace of mind, peace of mind.
The transformation of low nitrogen high quality fired boiler should be noted that what matters for retrofitting low nitrogen boiler should be noted that what? Of nitrogen oxide emissions is large, complex sources, environmental problems caused by acid deposition, fine particles, ozone, nitrogen oxides and analysis of contamination status must be further strengthened. If you do not take further measures to reduce emissions, with the United States and the United States to speed up economic development, population growth and urbanization, nitrogen oxide emissions will continue to grow in China in the future. Based on current trends, by 2030, emissions will reach 35.4x106 tonnes, will inevitably cause serious environmental impacts. Therefore, we must effectively enhance the emission control of nitrogen oxides. From this we can see that low nitrogen boiler is imperative! A check device to check for low NOX combustion gas before commissioning is in place, the gas pipeline flow is clean, whether the valve is open. There is a burner pipe leaks, reasonable pipeline installation. Discharging vent pipe valve from the foregoing, to ensure that no mixing of the air duct, and the exhaust pipe should be connected to the outdoor. Second, stable combustion and combustion of homeostasis Remember, combustion adjustment is the basis for all of the low nitrogen burner adjustment, as long as guaranteed under any changes in operating conditions of combustion stability and combustion of dynamic equilibrium, to burn steam temperature influence is even greater. Since the steam temperature is a sign flue gas heat value balance between the steam and heat absorption, this can be maintained as long as the dynamic balance, steam temperature can be kept stable. Third, the level of flame boiler boiler central flame center is also an important factor in high impact low-temperature steam. In the high temperature steam operation, the amount of coal combustor exhaust can be reduced, the amount of the lower stage burner of coal may be increased, and vice versa. Running low nitrogen burners, it should also be noted effect of different combinations of temperature steam mill. Steam at a low temperature exhaust composition regulating a large margin, the combination of the high temperature exhaust temperature adjusting stage so small margin overheat. It should be strengthened and soot blowing air distribution according to the situation.
