Low nitrogen of Changzhou gas fired boiler transforms low nitrogen of allowance file day and equipme

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: What does the technical pattern that low nitrogen transforms have, gas fired boiler faces the choice that low nitrogen transforms, low nitrogen is transformed, mean need to choose appropriate low nitrogen burner, and choice of right low nitrogen burner depends on the low nitrogen that burner uses transforms a technology, now at present the low nitrogen of the mainstream transforms technical course to be as follows: One, classification combustion: Classification combustion technology is classification fuel and air send the chamber of a stove or furnace, fuel classifications is in candle combustion area enters major fuel, low nitrogen transforms the price, a low nitrogen can be formed in blaze division remaining part reductive area, the azotic oxide that has formed carries this division share by reductive into. Classification combustion technology can ensure fuel burns adequately, of oxide of the nitrogen in lowering flue gas at the same time generate, can reduce 60% azotic oxide of the left and right sides to discharge. 2, burner mixes beforehand: Burner mixes flow to be as follows beforehand: Before combustion, fuel and oxygen mix adequately in burner, mix combustion temperature beforehand tall, low nitrogen transforms program, combustion strength is great, tianjin low nitrogen is transformed, control than undertaking to be being lighted for nothing, realize the control of pair of combustion temperature, control the generation of oxide of heating power nitrogen then. Reducing azotic oxide to create a field, complete jade annulus burns and burn to have very large latent capacity partly, than blame mix combustion to be able to reduce 85% azotic oxide of the left and right sides to generate beforehand, mix combustion to have taller combustibility beforehand nevertheless, light affect burner service life, bring calamity sex consequence to burner again. This technology still can cause on the high side of excessive air coefficient, increase smoke evacuation loss, reduce boiler efficiency to wait. More detail enters day and website of changes in temperature.

Day and changes in temperature are analytic notice relevant requirement about what about making clear gas fired boiler further low nitrogen transforms relevant requirement: 1, after low nitrogen transforms a project to carry out, discharging chroma to answer with oxide of nitrogen of gas fired boiler under 50 milligram / stere, cannot achieve a requirement, punish of executive stop production; After article print and distribute, whole town is all build (contain already approved did not build) oxide of nitrogen of gas fired boiler discharges chroma to answer under 50 milligram / stere; The blowdown of gas fired boiler permits azotic oxide gross to answer according to 50 milligram / of stere discharge chroma to give check and ratify. 2, boiler low nitrogen transforms means diversity, want course of logical choice technology, be on guard effectively the danger that install wind, prevent accident happening. To 10 evaporate ton / of hour above using boiler, do not suggest to use mix flaming to transform pattern beforehand; Answer to the center light boiler, do not suggest to use change of burner transform pattern; To using boiler, do not suggest to use those who transform burner to transform pattern directly. 3, transform the task to be being finished ahead of schedule and the business with transform the effect better, preferential the policy support that gives canal of lash-up of Qiu Dong season to accuse dissimilation of exempt equal difference to manage.
