Abstract
The environmental problems caused by industrial pollutants and global warming are on the rise. There is a need to develop a technology for reducing harmful pollutants. The co-combustion is getting serious attention by the scientists regarding its key facets to reduce the environmental pollutants. Its function is based on utilization of biomass with coal. In this work different types of biomass were used with coal samples to identify the suitable methodology. The biomass resource fulfills the requirement with reducing environmental pollutants and overcome energy crises. The ratios of biomass with coal samples were analyzed using stack gas analyzer. The banana tree waste (BTW) was found to be effective for reducing CO2 and CO emission. While, Cow dung manure (CDM) was found to be efficacious to decrease NOx. LC 80%+BTW 20% for SO2 and CDM for NO. To conclude, CDM and BTW decreases the emissions keeping blending ratio 80:20 with lignite coal to biomass in co-combustion respectively.
Highlights
I n the recent past, there have been increased complications concerning energy issues and global warming
It displays that the highest value of CO in flue gases concentration is about 1644.16 ppm after the burning of 60% lignite coal (LC)+40% banana tree waste (BTW) blend
The maximum percentage of produced CO2 was found to be around 4.37% for 90% LC+10% tree leaves (TL) blend and the maximum NO percentage was about 68 ppm for pristine BTW sample
Summary
I n the recent past, there have been increased complications concerning energy issues and global warming. It is due to emissions of sulfur oxides, carbon oxides and nitrogen oxides, abbreviated as SOx, COX and NOx respectively. There are existing various technology to decrease these harmful pollutants [1]. The co-firing of coal and biomass deploys best options for decreasing emissions and consumption of biomass. The biomass contents Rice husk and bamboo give less emissions by blending its high percentage with lignite coal (LC) to ratio of 80:20 respectively [2,3]. The biomasscoal co-combustion has proven to be an inexpensive, safe process, environmental affable and sustainable renewable energy option that fulfills reductions of sulfur oxides, carbon oxides and nitrogen oxides [4]. The biomass consumption is based to generate low amount of CO2 during combustion.
