Question

Describe the main elements of a low NOx combustion system as used in modern day boilers

Answer 1

as required above the low Nox combustion system is explained briefly with the main elements ,i hope you will understand the concept and a thumbs up will be really appreciated ,thank you

system ! of a low Nox Combustion Main elements formed then nitrogen and oxy you The generated by princippel nitrogen polutant, boilers are nitric oxide (NO) and dioxido (NO₂) Nitrogen collectively referred to as No . The contribution from different Noy sources to the total Nox levels varies anong metropolitan crear In Industrial boilers Nox is primarily formed ge Thermal Nox and fuel lor, Thermal Nox in nitrogen and oxygen in the combustion air Combine with one another at high temperatures in Fuel Nox is formed by the reaction of nitrogen in the fuel with otygen to the combustion air. In low or cumberstion system when firing fuels Nox formed by fuel-bound nitrogen can account for lo goy of the total no, lovel. One method to reduce Nox levele from boilers firing distillate on through the use of low nitrogen fuel oil, lowl nitrogen ople can contain cupto 15-20 times lose fuel-bound nitrogen standard No. 2 ou less than anale bound When you Nox oil is fired to boilers citillizing flue gas recirculation la reductio Go-tol over Nox emissions from standard ols have beo acheived. the flame results in lower flame temperatures and lower Thermal alox which is one of the main component in lour Nor combustion system formation which, in torn yoruly in lower overall play emissions lov oil is tired to fire tubes
