Chemical plant boiler needs to be done regularly to check which chemical plant boiler to regularly check what needs to be done? Need to ensure that accidents do not occur during a chemical plant boiler, enterprises not only need high quality and low price to buy equipment, and training people fireman from manufacturers chemical plant boiler and let them run the boiler, according to safety regulations in addition to regular inspection of boiler equipment. 1, during use of chemical external examination of the boiler, the boiler should be periodically checked external states, to ensure that the boiler housing and no signs of rust corrosion, the connection between different components not loose and loose, no change in appearance. CE boiler is not deformed. In addition, the need to check the boiler and the heat affected zone of weld defects such as cracks have, if necessary, should be checked using a surface inspection or other inspection methods. 2, many parts of the internal inspection chemical plant boiler internal check is necessary. Of any previous defective parts, the same test should be used or a method of adding the appropriate test method, a defective part has been repaired or re-inspection. Chemical boiler head, tube sheet, the furnace, the reburning header chamber and also regularly check. Also, check the boiler combustion device is burned and deformed. 3, the hydraulic inspection chemical checks need to specify the test pressure boiler pressure strength and tightness check boiler water pressure, attention do not participate in the hydraulic inspection pressure test connection assembly (e.g., boiler tubes, valves, etc.) inside and outside the scope of the partition It should take credible measures.

Before the end of December 2019 to complete the materials steel, building materials, nonferrous metals, thermal power, coking, casting and other key industries such as coal-fired boilers (including waste) transportation, handling, storage, transfer and process fugitive emissions such as in-depth treatment.

Before the end of June 16.2019 years, the 34 key towns thermal power, iron and steel (metalworking), chemicals, coke, foundry, mining, coal washing (gangue) plant, heating, building materials (cement, quarries, lime kiln, commercial concrete, brick tile, ceramic) and other companies involved in the installation of bulk material handling unorganized dust monitoring facilities. The scientific development of industrial enterprises dust control program, a clear corporate responsibility flushing and watering areas. Before the end of May 2019, the city's business involving bulk material handling import and export of materials and installation of vehicle washing equipment uptime, installation of access control systems (automatic identification standards to achieve the release of the vehicle) and video surveillance systems (monitoring records kept for more than one year).

Before the end of September 2019, the city completed 52 sets of 4530 tons of steam, ultra-low emissions coal-fired heating boilers 65 steam tons / hour or more coal-fired boilers, as well as municipalities and districts and is located in the county (city) built-up area, biomass boilers jobs. Engineered, the reference oxygen content of 6% under conditions, soot, sulfur dioxide, nitrogen oxides emission concentration of not higher than 10 mg / m, 35 mg / m, 50 mg / m. To complete the transformation of the city low nitrogen gas boiler, the end of October 2019, 1940.15 tons of steam units 610 complete the combustion of gas boiler a low nitrogen transformation, after the completion of NOx emission is not higher than 50 mg / m.

The end of October 2019, the city gas generators flue-depth treatment is completed, in accordance with particulate matter, sulfur dioxide, nitrogen oxide emission limits are not more than 30,200,300 mg / m execution.

Before the end of October 2019, steel, foundry, chemicals, and other enterprises to install CO CO emissions focus automatic on-line monitoring facilities; lime kiln flue gas companies to install continuous on-line monitoring facilities; the use of ammonia desulfurization and denitrification processes or business, the installation of continuous ammonia slip online monitoring facilities, all continuous on-line monitoring facilities and networking environment department.
