It is well known that coal combustion produces a large amount of So when it is burned. In addition, a small amount of SO3 is also generated. The concentration of S03 in the flue gas is 10~40g/L. Since the flue gas contains water (4 to 12), the generated SO is generated. Sulfuric acid mist is formed instantaneously. When the temperature is low, the sulfuric acid mist condenses into sulfuric acid, adheres to the inner wall of the equipment, or dissolves in the washing liquid, and corrodes the absorption tower and other related equipment. Therefore, in the course of use, combustion boilers will produce toxic gases such as sulfur dioxide. In recent years, the reform of coal-fired boilers is in full swing, and coal-fired boilers have successively “laid offâ€. The boiler industry will comply with national policies and eliminate coal-fired boilers. The future of the industry's energy-saving and environment-friendly boilers is promising.
Beijing: Sulphur dioxide exceeded 10 times in a boiler room Yesterday, the Beijing Environmental Monitoring Corps went to Pinggu Town, Pinggu District, and conducted a review of the coal-fired boiler room of the Beijing Taihe Dongyuan Property Management Service Center in the town.
Last month, the boiler house was found to have exceeded 30 times the sulfur dioxide concentration in the law enforcement inspection and the coal piles and cinder piles were not fully covered.
It can be seen from the scene that the chimney of the boiler room is still emitting black smoke, and coal piles of nearly 100 square meters are still not completely covered with dust-proof nets. As the vehicles enter into rolling up black smoke, the odor of the pungent smell is also filled in the workshop. Initial detection by environmental protection personnel found that the concentration of sulfur dioxide in the flue gas reached approximately 510 mg/m3, which was approximately 10 times higher than the standard.
The staff member said that the coal used in the boiler room may have too much sulphur, or that the amount of alkali that is desulfurized is not enough. It is understood that in previous inspections, the boiler room was to be fined a total of 60,000 yuan. Yan Xiangyang introduced that the results of this inspection will be announced after the final report.
Zhengzhou Bacheng Coal-fired Boilers Have Been "Laid-off"
“By preliminary estimation, the boilers that have been demolished and reformed can reduce 1 million tons of coal by one year,†said Bai Jianwei, director of the Pollution Prevention Department of Zhengzhou Municipal Environmental Protection Bureau.
The demolition and reform of coal-fired boilers in Zhengzhou City has completed 82% of the two-year mission, and it is estimated that coal combustion will be reduced by 1 million tons per year.
According to the data released by the Environmental Protection Bureau of Zhengzhou City, as of now, the task of dismantling and replacing 649 coal-fired boilers in Zhengzhou City has completed 532 demolition operations, accounting for 82% of the two-year mission. Among them, the city's five districts, the management committee 10 steam tons below the need to split (reform) 145 complete; 10 steam tons (inclusive) need to split (change) 118 (two years to complete), has now completed 49.
The boiler industry has introduced relevant policies for the protection of the environment. Due to the frequent occurrence of hazy weather, air quality has become one of the people's concerns that people are most concerned about, and the relevant market gates for environmental protection and energy-saving boilers have also opened. On June 14, 2013, the State Council’s Article 10 of the “Ten Policy†on Air Pollution Control proposed the “Comprehensive Renovation of Coal-fired Small Boilersâ€. The August 5 “Boiler Air Pollutant Emission Standard†solicited opinions and made a substantial step forward in the treatment of coal-fired boilers. Boiler remediation requires corresponding standards as a reference. Once the new standard is introduced, it can be used as a mandatory standard for boiler management.
In recent years, the green environment has attracted much attention, and various industries have advocated the production of energy-saving and environmentally friendly products. From August 7 to August 8, 2013, the Ministry of Environmental Protection held a national workshop on environmental policy legal system in Xi'an. During the meeting, it was emphasized that environmental protection is not only an important starting point for creating an upgraded version of the Chinese economy, but also an important symbol for realizing an upgraded version of the economy. The transformation of the green economy is a successful transformation. The rise of green is the rise of peace. It can be seen that the prospects for environmental protection boilers are considerable.
