correction curves boiler steam power plant

In the medium-high pressure industrial correction curves boiler steam power plant, the iron ion content is relatively low, the sacrificial resin and activated carbon composite double-layer membrane and the security filtration method are often used to remove the iron ion from the condensing water. Another danger that condensate water contains in excess of the national boiler water quality standards is that 60% ~ 70% of low-pressure boilers have a sewage discharge rate of more than 15% / 25%, while the national standard is 5% / 10%. Large discharge of high temperature water is the main cause of high energy consumption of boilers in China. Has attracted the attention of the relevant departments, is a difficult problem to be solved urgently.

Working principle of correction curves boiler steam power plant deaerator

Nowadays, the use of large-scale steam boilers is increasing. Compared with the auxiliary equipment, the most important thing for the boiler is to influence the deoxidation. Therefore, the knowledge of the deaerator is collected and introduced to you:

Then, 1t / h gas correction curves boiler steam power plant gas consumption per hour: 600000kcal / h ÷ 8600kcal ÷ 95% = 73.4Nm3 / h; hourly rate was: pipeline gas: 2.2 membered /Nm3×73.4Nm3=161.48 element.

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 correction curves boiler steam power plants, 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.
