Abstract

IMPROVING EFFICIENCY OF APRON FEEDER BY INSTALLING SPEED SENSING SWITCH

Dr. Rajendra K. Dhatrak* and Minal Salam

ABSTRACT

Apron feeders are very important in the Coal Handling plant and it plays vital role in coal unloading from Wagon Tippler to conveyers. The control system used for these Apron feeders is important for operating safe. But in some Coal Handling Plant still use of simple on/off switches for controlling the apron feeders. And these switches are only play roll of protection up to some limit. These Apron feeders control system are one of the biggest problem for the plant operator and maintenance engineers, being the cause of unsafe plant operation, which forced to plant breakdown and interrupt coal supply to boiler result loss of generation. Hence the efficiency of plant get reduces. This paper has been focused on required Apron feeders’ control and indication and alarming by installing a Zero Speed Switch with a Proximity sensors, which will fulfill requirement of smooth and safe plant operation.
