Under the policy of carbon neutrality, Sichuan Kelun Group responds to the national call to promote the low-carbon transformation of the pharmaceutical industry. For steam boilers with rated autoclaved capacity of 10 t/h, our technical team recommends a new low nitrogen VIC technology burner, model
Read More2021/8/18 · Low-NOx boilers employ various strategies to reduce the nitrogen oxides produced by boiler operation, including: • Steam injection • Selective or nonselective catalytic reduction (SCR or NSCR) • Flue-gas recirculation • The use of natural gas, rather than nitrogen
Read MoreIn tests on the North American boiler, a NO emission of 1,000 ppm resulted when firing the 5.8% nitrogen gas fuel at 15% excess air. A NO emission of 765 ppm resulted when firing the 2% nitrogen oil mixture at 15% excess air. Thus, the low NOX burner reduced NO emissions by.
Read MoreThe VariflameTM burner delivers high-efficiency performance in gas-fired package boilers with NOx emissions as low as 20 ppm (41 mg/Nm3) at 3 percent O2. Using advanced air-fuel staging techniques, the Variflame burner can operate with or without flue gas recirculation (FGR).
Read MoreLow NO x Burners (LNB) Low NO X burners and Low NO X burner Upgrades are available for both industrial and utility boilers burning a wide variety of fuels and have proven to be a cost effective way to reduce NO X emissions by 40% - 60%.Each system application
Read More2017/7/11 · Compared with other fuels, such as oil, the fuel-bound nitrogen in natural gas is low and considered insignificant. Prompt. Prompt NOx "occurs through early reactions of nitrogen molecules in the combustion air and hydrogen radicals from the fuel."¹ Recent "ultralow-NOx" designs have limited the generation of prompt NOx by minimizing the formation of substoichiometric regions in the
Read More2017/10/18 · The combination of the two techniques can help to reduce NO x emissions of natural gas-fired boiler burners from 60-90% (U.S. Environmental Protection Agency, 1998). Ultra-Low NO x Solutions Although modern systems emit less than one-third of the NO x produced by older units, an efficient, clean-burning traditional gas burner, operating at elevated temperatures, still produces significant
Read MoreOur Low NOx boilers combine energy efficiency with NOx-related upgrades and reduce nitrous oxides, save energy and reduce greenhouse gases. Low NOx boilers can utilize several design and equipment solutions to significantly reduce overall nitrogen oxide (NOx) emissions and reach levels under 30 ppm: Low NOx Burners – Low NOx boiler burners
Read MoreThe boiler efficiency is usually reduced to 84-85%, when a coal fired boiler is converted to natural gas. The biggest change is due to the combustion of Hydrogen. This is normally a 4% heat loss while firing coal and about a 11% heat loss while firing natural gas. When firing natural gas, other losses such as dry gas loss, moisture in fuel and

Read More2016/10/12 · Low NOx & Ultra Low NOx Burners. Undoubtedly, one of the most effective ways to reduce NOx is through Low NOx and Ultra Low NOx burners. Low NOx burners can reduce your NOx emissions to 30 pm. This equipment uses FGR and can maintain 3 to 5% excess O2 with strong controls. Low NOx burners offer good flame stability and turndowns that are less
Read More2018/9/26 · This CPD will consider why there is concern about boiler-emitted NOx and, specifically, how flue gas recirculation can reduce these emissions significantly. From 26 September 2018, under EU regulation No 814/20133, emissions of nitrogen oxides – expressed in terms of nitrogen dioxide – from water heaters should not exceed 56mg·kWh–¹.
