GET A QUOTE2002-1-25 · The formation of NOx. NOx emissions do not form in significant amounts until flame temperatures reach 2800 F. Once that threshold is passed, however, any further rise in temperature causes a rapid increase in the rate of NOx formation (A). NOx production is highest (B) at fuel-to-air combustion ratios of 5–7% O2 (25–45% excess air).
GET A QUOTE2018-6-13 · For natural gas-fired and No. 2 oil-fired boilers, thermal NOx represents the majority of NOx produced from industrial boilers. Thermal NOx emissions increase with increasing peak flame temperatures and are affected by oxygen availability in the boiler combustion zone.
GET A QUOTE2019-3-20 · As a result of the EPA's Clean Air Act, many state and federal environmental regulations require increasingly stringent lower NOx emissions compliance for manufacturing facilities, chemical plants, refineries, and industrial plants dependent on production processes that produce NOx, CO and other VOCs. These facilities are faced with meeting or exceeding low NOx (30 ppm) and even ultralow NOx
GET A QUOTE2014-6-19 · The effects of flue gas recirculation ratio, air preheating temperature, oxygen concentration, and fuel types on pollutants emission in the volumetric combustion system were investigated. According to the results, it was concluded the higher substitution ratio of biomass in a co-firing boiler, the lower emissions of NOx and SOx.

GET A QUOTE2018-6-13 · Thermal NOx is produced from the oxidation of nitrogen (N2) at temperatures above 1500°F. Thermal NOx is the primary source of NOx formation from natural gas and distillate oils because these fuels are generally lower or devoid of nitrogen. Fuel NOx, on the other hand, results from oxidation of nitrogen organically bound in the fuel.
