WNS Corrugated Furnace Steam Boiler
First, the first own specific needs and boiler manufacturers use to inform and get him to recommend some suitable gas boiler equipment;
In order to promote technological progress and sustainable development, improve environmental quality and protect public health, recently, the Liaoning Provincial People's Government of air pollutants for coal-fired power plants developed specific criteria (hereinafter referred to as the "standard"). This is the first time a set of policies Liaoning Province for air pollutant coal power plant.
"Standard" provides for pollutant discharge limits, surveillance and monitoring requirements within the jurisdiction of coal-fired power plant in Liaoning Province atmospheric and fugitive emissions control requirements. Since the implementation of the standards, air pollutant emissions coal-fired power plants all within the jurisdiction of Liaoning Province will be executed in accordance with the provisions of this standard.
2, since January 1, 2019, the emission limits of existing single output and more than 300MW generating units supporting the provision of a coal-fired power generation boilers execution table.
3, since 1 December 2020, the emission limits of existing single output 300MW generating units supporting the coal-fired power generation boilers and other power boilers as specified in Table 1 execution.
Sampling the exhaust gas (1) power plant, to be carried out in a predetermined position in accordance with the type of monitor emissions monitoring contaminants. In the discharge of pollutants should be set up to monitor the position of long-term monitoring holes, sampling platform and related facilities. When the sampling platform height from the ground greater than 40m, should be set by a lift platforms, lifts or other convenient and safe facilities. No elevator or elevator building coal-fired power plants, when the sampling platform height from the ground greater than 20m, should be set up safe, convenient electric monitoring equipment hoisting facilities.
Composition structure (3) continuous monitoring system atmospheric pollutants, technical requirements, test items, test methods and installation, commissioning, acceptance, operation management, data processing, etc. according to the provisions of HJ75 and HJ76.
(5) continuous monitoring system meter of air pollutants detection sensitivity, detection limit, and should meet the range of low concentrations of pollutant emission monitoring technical requirements, the concentration of nitrogen oxides include nitric oxide (NO) and nitrogen dioxide (of NO2), Determination of nitric oxide only has the ability to configure the analytical device of nitrogen oxides NO2 / NO converter.
(7) for coal-fired power boiler emissions of air pollutants sampling monitoring, sampling frequency, the sampling time and the operating load requirements,, HJ / T397 and related predetermined low exhaust gas concentration monitoring is performed according to specifications GB / T16157.
(9) shall be in accordance with the provisions of the enterprise "Environmental Monitoring and Management Measures" and the HJ819, HJ820 requirements of pollutant emissions and its impact on environmental quality around to conduct their own surveillance, monitoring and save the original records, public information.
Determination of air pollutants fired power plant analysis are shown in Table 2. After the release of the present embodiment national standard method of monitoring criteria pollutants, such as applicability to meet the requirements, the same applies to the determination of the corresponding standard contaminants present.
2, responsible for overseeing the management of this standard by the executive authorities and the standardization of administrative departments above the county level environmental protection. The results of the environmental protection departments at all levels and other relevant units in the enterprise supervision and checks can be instantly sampled or monitored the scene as determining whether acts of sewage meet emissions standards based on the relevant environmental protection and the implementation of management measures.
The transformation of low nitrogen boiler is now involved in the work of energy production and various industrial systems are often referred to, thanks to low-nitrogen combustion technology mature, more companies are willing to take the initiative to carry out the upgrading work is generally a reasonable the low-nitrogen transformation boiler construction program through rigorous study design and execution, after the implementation of low nitrogen boiler also need to change the final acceptance on behalf of better complete the work of reform. So in the end all sectors of the market Why should actively promote the transformation of low nitrogen boiler? First, innovative production methods can improve the performance of human industrial society is constantly developing innovative course of progressive, low nitrogen boiler which is very typical with a way of innovation and production ramp-up function through the core technology allows the dynamic performance of low nitrogen boiler upgrade several levels, so the transformation of low nitrogen boiler technology which is the genuine actively pursuing one of the important reasons. Second, we can establish a good corporate image from their own course of development in terms of the transformation brought about by low nitrogen boiler or the entire enterprise a poppet brand strength and market image, because these actively upgrading of consumer behavior allowed who for their strength and ability with confidence, but also allows partners to see their self-improvement sincerity. Third, the policy can be supported by relevant administrative departments of human industrial society is constantly developing innovative course of progressive, low nitrogen boiler is one of the very typical and have a good sense of the development of the social thing, so from In this sense the state and industry relevant authorities would be related technological change and transformation of low nitrogen boiler to provide policy support, including tax and other aspects are good good. From the enterprise itself to the relevant authorities are actively encourage and promote technological transformation of low nitrogen boiler, because in this way be able to quickly and effectively enhance the productivity and stability of the system upgrade boiler equipment, while this self-improvement of the enterprise itself enterprise strength and image is a good upgrade, but the industry as a whole to actively transform the low nitrogen boiler can be supported by relevant policies.
The dust, sulfur and nitrogen oxides in the flue gas of the boiler can be used to pollute the atmosphere. The emission index of the flue gas can reach several to ten times as many times as the environmental protection regulation when it is not purified. Measures to control the emissions of these substances include pre-combustion treatment, improved combustion technology, dust removal, desulfurization and denitrification. High chimneys can only reduce the concentration of pollutants in the atmosphere near the chimney.
