Quality low nitrogen boiler, thermal efficiency and capacity of the technology must be advanced. Third, the operational noise intensity Ruoyi to choose low-emission, high thermal efficiency of the boiler low nitrogen, customers can go to their attention operability and noise intensity. Quality low nitrogen boiler with intelligent control of the liquid crystal panel, the platform can interface with intelligent control, fully automatic operation. The customer shall focus on how the control system of the boiler, convenient degree operation. At the same time, the process needs to pay attention to the noise generated by the boiler operation, low noise intensity boiler should only be included in the selection. That is, the above-mentioned three ways to select high-quality low nitrogen boiler, in addition, it can also be analyzed by a variety of factors of production scale, market reputation and so on. Meanwhile, little attention boiler sales or low nitrogen Ranking Trade Ranking may well be a convenient solution. Only low nitrogen boiler energy saving, advancing with the times, in order to seize market opportunities to win customer favor.
Low NOx combustion technology Know Nitrogen oxides are one of the main sources of air pollution caused by the human body, animals and plants, the environment has a great destructive power, nitrogen oxide emissions will be too high a direct threat to our lives. Nitrogen and oxygen present not actively mixed together, but when the temperature reached 1600 deg.] C, nitrogen and oxygen in the air will be mixed to form nitrogen oxides. Currently, the use of better gas horizontal boiler for paper mill low NOx combustion technology has premix, FGR two kinds. First, the premix combustion fuel prior art into the furnace for combustion, pre-mixed with air, through the regulation and control precise optimum proportions. After addition of the surface to further reduce the combustion temperature in the furnace combustion technology, action to reduce nitrogen oxides. Two, FGR FGR combustion technology is the technology of flue gas recirculation combustion technology. Boiler flue gas produced after re-entering the conduit through the connecting part in the combustion in the furnace, reducing the combustion temperature of the fuel in the furnace, to reduce the effect of nitrogen oxides. If you are at this time headache boiler retrofit or low nitrogen want to buy low nitrogen boiler, can get in touch through the top free service hotline and fast boiler, we will be happy to assist you.
Jilin Province is located in northeast China, colder winter. Jilin Province is the autumn and winter air pollution problems are most acute period is the peak period of fog and haze. To reduce the frequency of occurrence of fog and haze, to reduce emissions of air pollution, according to "implement the central Jilin Province Environmental Protection Inspector feedback reform program", Jilin cities to carry out the 2018 autumn and winter special law enforcement inspection of non-electric coal-fired horizontal boiler for paper mills. Specific implementation of the program as follows.
2018 autumn and winter non-electric coal-fired boiler special law enforcement inspection action plan
First, the objectives
Through the "2018 autumn and winter special law enforcement inspection of non-electric boiler coal" action to further increase the intensity of emissions of air pollutants such as excessive penalties for violations combat, urge local governments and environmental protection departments to effectively implement the "Jilin province to implement the central environmental protection inspector feedback reform program, "Forced enterprises to speed up 10 tons of steam coal-fired boilers small and out of more than 20 tons of steam and non-electric coal-fired boiler pollution control facilities upgrade progress to ensure stable discharge standards.
Second, the scope of the inspection
Cities (prefectures) and Changbai Mountain Administrative Committee, Meihekou, Gongzhuling City, Hunchun.
Third, check the time
2018 Nian September 1 to November 30.
Fourth, inspection methods and content
Cities (prefectures) and counties under the jurisdiction of Changbai Mountain Administrative Committee to set up inspection teams to units in the area to take a cross peer review mode, Meihekou, Gongzhuling City, Hunchun to self-oriented.
The principle of mutual cross-check on the environmental violations found, the city's environmental protection departments at all levels in accordance with "should check to make investigation, should make a fine penalty, should be moved to make-shift" of errant given time out of the boiler, not dust removal facilities renovation no construction of desulphurization facilities are not required to install, networking, using automatic monitoring equipment, excessive discharge of pollutants and other acts take full advantage of "environmental law" and supporting measures to implement daily basis penalties, limited production shutdown, sequestration, administrative detention measures to deal with.
Focus on examination of the following:
(A) the progress of 10 tons of steam coal-fired boilers little out of work. According to "implement the central Jilin Province Environmental Protection Inspector feedback reform program," according to the time limit set by local governments, the progress of the phase-out of coal-fired boiler 10 tons of steam since 2014, the province's illegal 1570 newly registered units to be checked.
(B) more than 20 tons of steam coal-fired boiler non-electric dust removal, desulfurization facilities upgrade progress, automatic monitoring equipment installation, networking, usage. By ShengTing 6, July scheduling, the current to complete the rectification stage 717, stage 108 does not start the rectification, the rectification is 277, automatic monitoring equipment table 140 is not installed, the slow progress of the rectification. To complete the transformation around the boiler on-site verification, focusing on inspection facilities dust removal, desulfurization facilities upgrading and installation of automatic monitoring equipment, networking, usage. Percentage being modified, check the current progress of the major transformation of the situation, progress of the project, the time frame for completion, safeguard measures taken, it requires the use of boiler units issued commitments. For failure to start the transformation, to identify the main reason for not starting. If we do not transform the way in which the pin number to take all necessary construction and renovation tasks must be completed in accordance with the requirements of 30 September.
(C) boiler emissions standards. To install automatic monitoring equipment to monitor them than to confirm the validity of the data.
