hot water boiler standards

Gas hot water boiler standards is better than ordinary boiler three salient features 1. Energy Saving toxic gas emission rate is much lower than ordinary gas hot water boiler boiler, sampling standards in full compliance with national standards of environmental protection agencies, because these devices were powered by a net importer burner, during operation of electronic auto-ignition, combustion automatic, self-extinguishing, performance is very stable, so excellent combustion efficiency, exhaust gas content is very low, the oxygen content in the nitrogen produced in the boiler emissions meet international standards. 2. The selection of high quality, long life gas hot water boiler service life longer than ordinary boilers. Many advanced gas equipment are multilayer centrifugal glass wool insulation, but also to prevent rust and less heat loss. These excellent material, on the one hand to ensure a high boiler heat transfer equipment, significant cost savings for businesses, on the other hand excellent material, production of fine, to ensure that such equipment has a longer than normal gas hot water boiler life. 3. fully automated control with the development of science and technology, intelligence also spread to the field of gas hot water boiler equipment, gas hot water boiler intelligent control are used, the operator need not operate as an ordinary boiler to the scene as the operation switch, but by controlling intelligent control room computer system to complete the whole process, which greatly protect the personal safety of operating personnel. Also manufacturers will also provide after-sales service, ensure that the entire purchase, installation, maintenance train service failure. It is gas hot water boiler equipment with excellent quality, long service life, intelligent operation to reduce personnel accidents, and improve after-sales service is better than ordinary boiler prominent feature, complete category of gas hot water boiler facilities was more and more users of all ages. With escalating gas boiler technology optimization, gas boiler will bring a better experience for the user, and to meet the needs of more people.

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.
