In this study, numerical models of a 350t/d MSW incinerator were established to study the effects of different air supply methods (such as different ratios of primary air and secondary...
In order to investigate the influence of the secondary air, the effects of different secondary air velocities and angles on the combustion process and NO formation characteristics were studied
By optimizing the primary and secondary air distribution ratios, the initial NOx generation was reduced by 8.39%. When 20% of the recirculated flue gas was introduced as secondary air,...
The study showed that optimizing the ratio of primary air to secondary air, adjusting the air speed and distribution, significantly reduced NOx emissions, improved the in-furnace temperature
By optimizing the air distribution ratio of primary air to secondary air, the initial nitrogen oxide production was reduced by 8.39%. Their study proved that the air ratio has a significant impact
The relationship between secondary air, NOx concentration, and thermal efficiency was given.
minimum air is stoichiometrically required for combustion. For incineration processes however, far more air is supplied tha is actually required on a purely chemical
To reduce the NOx emission concentration of waste incineration boilers and improve the thermal efficiency of incinerators, the combustion process of a 600 t/d incineration boiler was numerically
The research provides support for improving waste incinerator efficiency and stability while reducing NOx emissions, aiding the sustainable development of waste incineration technology.
Typically, the less the amount of air delivered to the primary chamber (i.e., starved-air mode), the more air and the greater the auxiliary burner (either oil or natural gas fired) input to the secondary.
