1.3 Fuel Oil Combustion
Fuel nitrogen conversion is the more important NOx-forming mechanism in residual oil boilers. It can account for 50 percent of the total NOx emissions from residual oil firing. The percent conversion of fuel nitrogen to NOx varies greatly, however; typically from 20 to 90 percent of nitrogen in oil is

Characteristics of Particulate Emission from a Biomass
2-enriched air and oxygen–air–steam had been studied (Campoy et al.,2009). Use of oxygen or steam as the gasifying agent improves the quality of producer gas in terms of heating value or hydrogen content. But the high cost and energy consumption of O 2 or steam generation makes the process unfavorable. Palm oil mill boiler fly ash (POMBFA

Air Pollution Final | Combustion | Exhaust Gas
Air flow needs to be maintained near the minimum practical (not quite smoking) level. The automatic air flow control system needs to do this continuously as the boiler load changes. Precise control of excess air is the first and most important step in controlling emissions from boilers and furnaces.
