How to put ordinary gas low investment costs boilers 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.
Electric low investment costs boilers is an integral part of the winter heating gas 1, which is not the most important electric boiler placed around combustible materials (paper, cloth and other flammable), from the source to reduce the occurrence of such fires. 2, the electric heater is not installed, plug, and pull the resistance wire forget overload, or aging of the power cord will also cause a fire. 3, the use of electric heaters when the edge should keep someone when not unplug the power cord, do not pull a lot of people used to switch, but it will also give the opportunity to contribute to the fire. 4, the case of a sudden power failure, disconnect the plug should heaters to prevent a sudden increase in current when an incoming call and fire.
We know the difference between fuel oil and gas low investment costs boilerss, gas or oil-fired boiler choice is not difficult to solve: first, to see if fuel oil sales unit is located within close range, then give up if no oil-fired boiler, long-distance transport will increase fuel cost. Second, you can understand the situation to the relevant units subscribed natural gas pipelines, though such early to spend more, but in the long run, can save a lot of money as a unit.
Recently, the Guangzhou City issued an action "Guangzhou 2018 annual work plan for comprehensive prevention and control of air pollution," the bureau of law enforcement to monitor the detachment on August 28 = 29 organizations launched a special enforcement action against a biomass low investment costs boilers.
The special enforcement action by the municipal and district levels of environmental protection departments jointly launched, deployed Yuexiu, Tianhe, Haizhu, Huangpu, Conghua five district environmental protection law enforcement backbone, with the Guangzhou City Environmental Protection law enforcement inspection detachment composed of 18 cross-law enforcement group, to increase the city all registration to carry out quality checks of 125 biomass boilers in the book, focus on examination of Guangzhou boiler emissions monitoring system in Zengcheng District registered the existence of complex biomass boilers coal or other high-polluting fuels, whether there are special furnace and supporting bag dust removal facilities, whether the normal operation of the boiler control facilities, whether discharge standards as required entry and update Guangzhou boiler emission monitoring system and other issues.
After verification, the registration system by the city list in the boiler has been disabled (off or relocated) boiler station 43, not included in the other eight found regulatory list table 133 actually inspected. Among them, 28 units involving suspected violations accounted for in the boiler problem with the boiler (90 units) ratio of 31%, the problem of coal-fired boilers in complex 2, the resurgence of firewood, 11, allegedly did not apply for environmental protection procedures, waste gas treatment is not installed facility or facilities are not the normal use and other illegal activities 15. For complex high-polluting coal and wood fuel boiler according to law-site seizure and transfer penalties and territorial environmental protection departments to follow up treatment in accordance with the relevant provisions of Article 107 of the "People's Republic of China Air Pollution Prevention Law." The rest were arrested for illegal transfer of territorial environmental protection departments for investigation.Free Chat
