Abstract/Contents

Abstract: The growing number of brick kilns in Bangladesh has contributed to an air pollution crisis that has had detrimental effects on the environment and human health. Harmful particulates from the kilns are created, in part, by inefficient coal burning processes. Previous research has shown that incomplete combustion of Alkanes, like coal, can lead to the formation of carbon monoxide and black carbon smoke. Former Mechanical Engineering capstone teams recognized that these harmful emissions could be mitigated through an automatic coal feeder system, which distributes coal over time and therefore promotes complete coal combustion. However, the automatic coal feeder device implemented by previous teams and our partners in Bangladesh disregarded the impact of damp coal, an inescapable component of coal used on kilns, which causes clogs and stops coal output. In order to deliver a functional device that will operate in all conditions, including with damp coal, our team created an added internal rotation component which was successfully able to disturb the coal and prevent the formation of clogs. Our findings indicate that our internal rotation device is successfully able to disrupt all forms of clogs, maintain a consistent coal output, and hold enough coal for 2 hours without stalling the motor.
