Why is it important to reduce NOx?
NOx reduction is important in both marine and stationary applications. NOx is a component in ground-level ozone and smog, and it contributes to acid rain. NOx is also an indirect greenhouse gas that contributes to global warming and climate change.
What is the difference between low NOx and ultra low NOx?
When it comes to the difference between the Low NOx and the UltraLow NOx, it is determined by the standards of the local EPA basing on the type of the heating equipment. When it comes to Low NOx, it can reduce the emission of NOx to 30 pm. For UltraLow NOx, the emissions are between 7 to 15 ppm.
What is ultra low NOx burner?
Ultra Low NOx burners DTPJE are designed to satisfy the most stringent restrictions on pollutant emissions on fuel gas firing, with or without Flue Gas Recirculation (FGR) while providing high combustion efficiency and reliability with all kinds of gaseous fuels.
What reduces NOx during combustion?
One way of controlling NOx emissions is to use low-nitrogen fuels. Another is to modify combustion conditions to generate less NOx. Flue gas treatment techniques, such as selective cata- lytic reduction (SCR) processes, can remove NOx.
What is a Low NOx engine?
There are currently three low NOx standards that an engine can be certified by CARB to meet: 0.02 g/bhp-hr, 0.05 g/bhp-hr, or 0.10 g/bhp-hr. In some cases, engines may test at emission levels at or below the Optional Low NOx Emission Standards, but they are not certified by CARB to meet the low NOx standard.
What is a typical acceptable NOx value?
between 50 and 1000 ppm
Concentrations of NOx in untreated diesel exhaust are typically between 50 and 1000 ppm. If concentrations are given in mass units, NOx is usually expressed as NO2 equivalent.
How is NOx reduced?
NOx emission can be reduced by primary methods such as retard injection, fuel nozzle modification, change of compression ratio, water direct injection, water emulsification, exhaust gas recirculation (EGR) and secondary method such as selective catalytic reduction (SCR).
What does NOx do to the body?
NOx mainly impacts on respiratory conditions causing inflammation of the airways at high levels. Long term exposure can decrease lung function, increase the risk of respiratory conditions and increases the response to allergens.
