ELECTRICALLY ENERGISED MAGNETIC SEPARATOR SYSTEM CONTROL WITH 8051 MCS AND LOGIC CONTROLLERS

- Magnetic separators are installed to catch and separate ferrous materials that might come along with lignite.Electrically operated Magnetic Separators (shortly MS systems) are the main bones of Lignite Handling System (LHS) systems incorporated in Receiving and Transfer of lignite. The major aims of such systems are “to Remove Ferrous materials (minimum size to 50 kg) of any shape”. Power generation mainly depends on boiler. Lignite needs for boiler will be supplied from Lignite bunkers. One of the activities of LHS system is to transfer lignite from TPS-II stockyard to Boiler bunkers. From bunkers the lignite has to take another travel to Pulverizing mill system, then it reaches boiler furnace with powdered and pre-heated state. We aim to do study of Magnetic Separator system and then we are going to prepare alternate control arrangements by introducing two latest embedded system technologies. They are 1. With the supports of Micro- controller based (8051 Micro Controllers) system 2. With the stand-alone Brick type PLC introduced system configuration Trouble shooting for misbehavior is most common happening and it would consume more time to resolve. Hence up-gradation is highly required to modernize PC friendly magnetic separator control facility with the help of PLC.
