It is reported that Shandong Province to further promote the action of atmospheric pollutants governance, but also to "defend the blue sky strategy" escalating, the Shandong provincial government amended the new "Regional Air Pollutant Emission Standards" and other three local standards, as the province's mandatory local standards of environmental protection, on November 1, 2019 formally implemented.

1, to improve the standard index-related emissions, can improve the level of clean production, reduce pollutant emissions, Forced out of high-emission equipment, improve air quality. The revised standard canceled the densely populated high-polluting industries sewage privilege, the use of emissions phased strategy partition; divides a region of Shandong Province as the core focus, and general control zone, different regions perform different emission limits, based on the location of the enterprise partitioning control requirements.

2, a new round of defense blue sky "Strategy" will be ultra-low emissions standards covering all coal-fired boilers in Shandong Province, and will gradually promote the non-coal industry, requires iron and steel, coking industry emissions to meet ultra-low emission standards. Key building materials industry emissions control area cement, ceramics, lime, glass, etc. are also required to achieve ultra-low emission standards, the general control zone cement, ceramics, glass and other building materials industry emission requirements more stringent than the national standards.

3, changes in air pollutant emission standards in the current round of revisions is the biggest "air pollutant emission standards iron and steel industry." The new revised standard will help eliminate a number of small-scale, backward technology, compliance governance hopeless small-scale iron and steel enterprises, and guide the existing steel enterprises discharge standards by clean energy alternatives, etc., so as to promote Shandong Province, energy, industrial restructuring, improve the quality of atmospheric environment.

4, according to monitoring data, 2018, Shandong fine particulate matter (of PM2.5), particulate matter (of PM10), sulfur dioxide (SO2), (NO2) average concentration of nitrogen dioxide fell 14.0%, 8.5%, 33.3 %, 2.7%; the number of days of heavy pollution fell for 5 days. Wherein the fine particulate matter (of PM2.5) than the average concentration of 2013, 2015 decreased 50.0%, 35.5%.

According to the "2013 Shandong Province - 2020 air pollution control plan" in 2020, the province's basic ambient air quality standards, compared with 2010 improved by 50%. Since 2013, Shandong "broken wrist" environmental pollution, has released various standard 102.

Softened water water tube boiler manufacturer is equipped with the device through a qualified boiler feed water treatment, which is to extend the life of the boiler, ensure the safe operation of the important issues. Boiler feed water should comply with GB1576-2001 "industrial boiler water quality," the relevant requirements.

Gas steam water tube boiler manufacturer steam quality requirements which gas stove quality What are the requirements 1, welding gas steam oven must be operated by welders holding boiler and pressure vessel certification of welders. 2, weld dimensions meet the design drawings and process documents, bead height is not less than the base material, the base material with a smooth transition. 3, gas steam oven weld and heat affected zone no cracks, holes, craters and slag. 4, the weld depth of undercut hole is not more than 0.5mm, the total length (the sum of both) is not more than 1/4 of the circumference of the tube, and not more than 40mm. 5, gas steam boiler construction welding procedures and strict adherence to standards and other relevant regulations, and make construction records welded to record the record

"Safe distance" water tube boiler manufacturer is how much? Do not let the boiler struck a "spark"! For this special boiler equipment, its installation and boiler room are big construction projects, this is not like we normally use home appliances, on the need to consider the question of how or where to install. A safe distance from the boiler in the boiler room is how much? Safe distance from the boiler and the workshop is how much? Security between the boiler room and the building What is the distance? These data collection is good, boiler go safe "start." A boiler in net distance between the boiler and the boiler room safe distance from the building interior walls of the boiler room, fireman space should be left operating, maintenance and arrangement of auxiliary equipment. 1, spacing steam boiler furnace 1 ~ 4t / h, hot water boiler 0.7 ~ 2.8MW, not less than 3.0m; steam boiler 6 ~ 20t / h, hot water boiler 4.2 ~ 14MW, not less than 4.0m; steam boiler 35 ~ 65t / h, hot water boiler 29 ~ 58MW, not less than 5.0m. Note: When replacement boiler tube furnace, blast furnace spacing should meet operational requirements. For 6 ~ 65t h steam boiler / hot water boiler 4.2 ~ 58MW when setting glue instrument control chamber furnace, boiler to the front end of the control chamber can be set to meter spacing 3m. 2, the channel spacing steam boilers and rear side 1 ~ 4t / h, hot water boiler 0.7 ~ 2.8MW, not less than 0.8m; steam boiler 6 ~ 20t / h, hot water boiler 4.2 ~ 14MW, not less than 1.5m ; steam boiler 35 ~ 65t / h, hot water boiler 29 ~ 58MW, not less than 1.8m. Further, when it is desired sootblowing, stirring the fire, slag, installation or maintenance spiral Cleaner, channel spacing should be able to meet the requirements of the operation. Also add that the distance between the highest and the lowest operating point of the boiler structure boiler room at the top of not less than 2m. Second, no uniform workshop boiler is connected between the boiler room and a safe distance from the production plant, the two must be independent, typically 5 meters. Third, the boiler room and a safe distance from buildings 1, a safe distance from the boiler room and a class of high-rise building is 15 meters: 9-16 refers to a class of high-level layer (up to 50 m height); 2, boiler room and multi-residential buildings the safety distance is 13 meters: 2-9 refers to multi-storey buildings layers residential and other civil construction height does not exceed 24m; and 3, a safe distance from the boiler room to the podium before is 10 meters: the podium with senior connected height generally less than 24m. Note: the outer skirt means high-rise building subject projection range, the height of the building is connected to high-rise buildings of no more than 24 meters annex.
