Alternative Fuel Sources to Reduce Air Pollution in Industrial Boilers

The boiler is one of the most energy-consuming applications in industries. In Sri Lanka, several biomass sources can be used as alternative renewable fuels for the boiler. Various industries use biomass boilers. Biomass boilers also emit some air pollutants, which should be minimized. Also, deforestation to meet the biomass demand is another problem. Using suitable combustion technologies, non-conventional biomass-based fuels such as briquettes, biomass can be consumed sustainably with controlling air pollution. Air pollutant emissions, usage of industrial biomass in Sri Lanka, Available alternative biomass fuels, their impact, and different combustion technologies have been discussed to identify suitable alternative fuels and the potential for air pollution reduction.
