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.
Four kinds of gas boiler companies using biomass combustion analysis: gas boiler is a general term for burning biomass boiler is in accordance with the division, in fact, combustion gas boiler is also very different. Gas boiler combustion great influence on the overall design of the boiler. The fuel should characteristics, boiler capacity and user requirements, in order to make the appropriate design of the gas boiler combustion mode to meet user demand.
Each boiler companies using biomass will generate 250 tons/hour of low-pressure steam for the alumina refinery; however, the design allows for conversion to high-pressure steam generation for the future addition of a steam turbine for electricity generation.Coal or biomass will be the primary and backup fuels, respectively.
Second, biomass steam boiler
