Boiler low nitrogen transforms technical day and Jiangsu of family name of ground of heart of change

Day and changes in temperature analyse Chinese environmental protection, energy-saving policy: Increase finance budget considerably with local government, incentive and energy-saving. 2007, finance arranges capital of 23.5 billion yuan of finance to be used at support in all energy-saving decrease a platoon, among them, the national debt that is used at energy-saving respect and budgetary are cast in all 9 billion yuan. Local government also increased the finance to energy-saving job to support strength, 21 provinces (area, city) establish or increased energy-saving reduce a special fund, total capital dimensions exceeded financial to support strength, use at faculty of allowance of audit of company energy resources, energy-saving center construction, eliminate contract of backward allowance, promotion energy management and medium and small businesses are energy-saving award (or allowance) etc. Adjust policy of concerned taxation, price, banking, stimulative industry is energy-saving decrease a platoon. In June 2007, approval is released " the announcement that the Ministry of finance leads about moving small part commodity to export drawback " , cancel 553 " high cost can, sex of tall pollution, resource " the exit drawback of the product, consider to be opposite height of the sources of energy is concentrated model commodity imposes export custom duty; In November 2007, legal system does pass " resource duty reforms scheme " , draft will, the levy means of the resource such as natural gas, coal by " from the quantity plan proof " instead " from valence plan proof " , among them the tax rate of duty of coal natural resources will raise 3 ％ from 1 ％ ; Adjusted consumption tax at the same time, increased resource tax rate.

Day and changes in temperature analyse: The meaning that boiler low nitrogen transforms, want to know why to undertake low nitrogen is transformed, know a few main things first, azotic oxide. The definition of azotic oxide, by the nitrogen, compound that two kinds of elements comprise oxygen. Common azotic oxide has 5 oxidation 2 nitrogen (N2O5) , (NO2, gong Zong is lubricious) , (NO, colorless) , (N2O) , divide 5 oxidation among them outside solid body is being shown below 2 nitrogen normal, other nitrogen presents gaseous state below oxide normal. The azotic oxide that regards air as contaminant (NOx) often points to NO and NO2. The harm of azotic oxide, azotic oxide can stimulate lung, make the person resists harder the respiratory system disease of cold and so on, respiratory system has the personage of the problem to be like a patient, the meeting is more accessible. To children, azotic oxide may cause lung development damage. Research points out oxide of long-term and inspiratory nitrogen may bring about lung construction to change, but still the azotic oxide content that cannot causes this kind of consequence certainly and inspiratory gas time. More detail enters day and website of changes in temperature.

Day and changes in temperature are analytic inform about what about making clear gas fired boiler further low nitrogen transforms relevant requirement (Ning Huan of file of bureau of environment of Nanjing town organisms' habits does [2019] 62)----Environmental protection of river north new developed area and water Wu bureau, each area (garden area) environmental protection bureau: To improve whole town ambient air quality further, basis " Nanjing city is hit win blue sky to guard battle 2019 year implement plan " (Ning Zhengchuan [2019] 37) requirement, whole town is wanting to begin low nitrogen to transform with gas fired boiler. Be as follows concerned requirement clearly now: One, working target: 1, before September 1, 2019, all is in with 4 evaporate ton / hour above gas fired boiler should finish low nitrogen to transform a project. 2, before December 31, 2019, whole town is all using gas fired boiler to should finish low nitrogen to transform a project. All is in already was in with list of gas fired boiler " the announcement that makes air of battle of good pollution assault fortified positions administer task of partial focal point about make known to lower levels " (peaceful corrupt prevent assault fortified positions to point to do [2019] 36) in give clear, no longer separately make known to lower levels.
