Emissions reduction from an oil burner by air staging

Abstract

The increasing concern and awareness among the public regarding the quality of environment that currently become more polluted due to combustion activities, particularly in industrial field has instigate the researchers and industrialists to find more comprehensives and enhanced technologies to reduce the so called pollutants emissions such as NOx, CO, CO2, SOx, VOCs and particulate matter (PM). These pollutants gases do not only harmful to the environment but also have appalling implications on human health and to all inhabitants in our ecological system. There are a few well-known methods that can reduce the emissions of those pollutants either by combustion modifications or post combustion treatment that is effective in reducing emissions pollutants but much expensive than the former. For this present project, the method that will be adapted is air staging method. By air staging techniques, some of the combustion air will be directed into the primary combustion zone, while the remaining air is directed into secondary zone. The function of the secondary air is to reduce the peak flame temperatures, which theoretically reduce the emissions of NOx emissions. The primary concern for this project is to investigate the reduction trend of NOx emissions. However other emissions such as CO, CO2 and SO2, will be accounted too.
