Designing Work Facilities In Dust Disposal Station (Silo Ash) To Reduce Air Pollution And Ease Maintenance With Quality Function Deployment (QFD) Method

Abstract

PT. ABC has an ash handling system to collect, distribute, store and capture dust when the combustion process in the boiler burner has been completed so that the gas coming out of the clean chimney and coal dust is not polluted. Given the importance of this equipment, it is necessary to create a reliable and efficient system to improve generator performance for customer satisfaction. On the line ash handling system from ESP to the ash silo that serves the temporary collector before being taken to ash disposal for waste. Each equipment is expected to work optimally so that the dust handling system runs according to its function. The root fan under the silo ash is a very risky position when viewed from the current condition. The current position causes the fan filter to become dirty and requires high maintenance time and costs because the filter life is reduced (replaced too quickly). Disposal of ash (silos) has a significant impact on the environment around the station which causes air pollution which makes the surrounding engine conditions contaminated by dust, making maintenance difficult. Seeing this condition, designs that can reduce air pollution and facilitate maintenance are root fan removal, engineering design in truck shelters, and engineering designs on the ash silo holder frame. This design is able to reduce air pollution while facilitating maintenance because it reduces fly ash.
