Combustion of Changzhou boiler low nitrogen transforms better manufacturer boiler low nitrogen

Day and changes in temperature analyse: Why should undertake low nitrogen is transformed? Low nitrogen transforms pattern basically is control of low nitrogen combustion and extreme processing, pilot of low nitrogen combustion is low nitrogen transforms pattern to heating power model the effect of azotic oxide is most apparent. Extreme processing method includes include: SCR, SNCR, oxidation absorbs law and metallic catalysis law. Be known according to me, be in Beijing, majority low nitrogen is transformed is medium or small gas fired boiler is mixed light continuously of machine. If be gas fired boiler and the word is main transform way that light machine low nitrogen to transform continuously,can be low nitrogen only combustion controls this one. Low nitrogen transforms pilot of low nitrogen combustion to basically have mix combustion to reach beforehand diffuse type burns, mix combustion to include deficient beforehand beforehand mix up water-cooling is mixed beforehand, and diffuse type combustion low nitrogen transforms pattern basically is to classification combustion + inside flue gas / outer circulation. Above lists low nitrogen transforms means to be discharged to reducing azotic oxide all effective, the proposal that if have need really,low nitrogen transforms is used classification combustion + the means that flue gas circulates.

Day and changes in temperature analyse: At present low nitrogen burner transforms a principle to be roughly by low nitrogen combustion: Level burner, the level burner that according to classificationing combustion principle designs, make fuel and air section mix combustion, as a result of combustion deviate theory equivalent is compared, reason can reduce nitrogen generate. Oneself recycle burner, one kind is the pressure head that uses combustion air, absorb partial combustion flue gas, enter burner, mix combustion with air. As a result of flue gas recycle, the thermal capacity of combustion flue gas is large, combustion thermal drop is small, NOx decreases, namely flue gas outer circulation. Burner of recycle of another kind of oneself is a partial flue gas enter recycle inside burner directly, join combustion process, this kind of burner has restrain oxidation nitrogen and energy-saving and double effect, circulate inside flue gas namely. Shade burner, its principle is to make one part fuel has made thick combustion, another part fuel has made weak combustion, but empty tolerance keeps changeless on whole. Because two parts are in,deviate chemistry equivalent burns than falling, NOx is very consequently low, this kind of combustion calls deviate to burn again or blame chemistry equivalent burns. More information is accessibility Jiangsu day and website of equipment 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.
