Different meaning of the data and the oxygen content of the exhaust gas fired supermarket atmospheric boiler price: A boiler oil-fired boiler which, it is explained below target, because through knowledge and understanding of this kind of boiler, can broaden everyone's knowledge, and at the same time, familiar with the different boiler type, so as to achieve a comprehensive understanding of the boiler, do not miss any of which. 1. fuel boiler, 0.5 tons and 0.35mw, its meaning is the same as you? An oil boiler, and 0.5 tons 0.35mw these two parameters, which specifically refers to, and is not the same, because the former is the rated evaporation of the boiler, while the latter refers to the rated power of the boiler or the rated for heat. In addition, in the unit, the two are not the same. So, obviously, on this issue, that the answer is not the same. 2. Industrial boilers, oil-fired boiler is why the general level? In addition, the oxygen content in the exhaust gas boiler fuel, how much is more appropriate? Industrial boilers, if its use is oil-fired boiler, then, it generally is a Class B boiler, that is, the pressure of the boiler is rated at 2.5MPa or less. Oil-fired boiler exhaust gas oxygen content and, in general, is controlled within the range of 3% to 5% is appropriate. If less than 3%, the problem of incomplete combustion occurs.
Low nitrogen supermarket atmospheric boiler price 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.
How fuel (gas) supermarket atmospheric boiler price stack height standards should be implemented as specified? Oil, gas boiler chimney of not less than 8 meters, the height of the boiler chimney by specific approval of environmental impact assessment documents OK. When there is a building within a radius of 200m from the new boiler room around the chimney, the chimney should be higher than the tallest building in more than 3m. "Boiler air pollutant emission standards" -GB13271-2014
Recently, the Ministry of Environmental Protection by the volatility of the newly revised "Boiler Air Pollutants Emission Standards" released in July this year, the implementation of this standard is known as by far the most stringent air pollution emission standards for supermarket atmospheric boiler prices, boiler caused by the manufacturing sector.
Compared with the existing standards, new standards not only revised the traditional particulate matter and sulfur dioxide emission limits, for the first time proposed emission control standards for nitrogen oxides and mercury, Forced boiler manufacturers have to upgrade technology, from the source control boiler discharge atmospheric pollutants.
One side is desulphurization and denitrification entered the final stage, while the new emission standards of air pollutants are being introduced amendments to the boiler. Such as pollutant emissions from large wide range of small capacity monomer emission coal-fired boilers and other issues close to the ground long standing will once again be enlarged, comprehensive improvement of coal-fired boilers will undoubtedly become the next focus of urban air pollution control. Analysts believe that the implementation of the new standard direct-driven investment in environmental protection will reach 370 billion yuan to 4500 yuan, while the boiler manufacturing industry is facing exams has also led to the relevant environmental protection equipment market to break out again.
By the end of 2011, our country in the boiler 620,300 units, of which 09,700 units utility boilers, industrial boilers 610 600 units, with a total capacity of about 3,515,900 kilowatts. In 2012, industrial boilers reached 62.4 million units, about 98% of the total number of boilers.
In industrial boilers, coal-fired boiler is more than 80%, the annual consumption of 490 million tons of standard coal, the average efficiency of 65% to 70%, emissions remain high.
In 2012, coal-fired industrial boilers cumulative emissions of dust 4.1 million tons, 5.7 million tons of sulfur dioxide, nitrogen oxides 2.0 million tons respectively, accounting for 32% of total national emissions, 26% and 15%, a major cause of fog and haze one of the reasons.
For this reason, in the 2013 set off a nationwide clean energy alternative coal-fired boiler boiler, more than one place Shandong, Shanxi and other relevant measures have been introduced on clean energy alternative to coal-fired boiler work. "The introduction of the implementation of the most stringent standards, will set off a coal-fired boiler in the second round.
Four existing small and medium sized coal-fired boilers in China. One pollutant emissions from large, wide surface. Second, small-cell capacity, the average capacity of 8 tons / hour, the number of 10 tons / hour of small coal-fired boilers is 42 million units, accounting for two-thirds of the total. Third, emissions close to the ground, a great impact on quality. Fourth, boiler technology, main and auxiliary mismatch, poor health. In addition, most small boiler lack of dust removal, desulfurization and denitrification equipment, led to the current sulfur dioxide and dust emissions from boilers widespread non-compliance.
From the present point of view, domestic clean energy technology matures, the implementation of new emission standards for technology development has brought very good driving force for the future, who can stable up to standard technical requirements of the country, will have a presence in the market value Otherwise it can be eliminated.
