RECONSTRUCTION OF POWER CONTROL CABINETS OF ELECTROMAGNETIC RAPPERS ON ELECTROSTATIC SEPARATOR OF BLOCK B1 IN TPP KOSTOLAC B

Proper operation of rappers, regardless of the way they are started, from a technical-technological point of view is one of the conditions for the best possible operation of the electrostatic precipitator (ESP), i.e. the least amount of powdery substances emitted into the atmosphere. The total number of electromagnetic rappers of both ESP chambers on thermal block 1 in TPP Kostolac is 670. Control is realized with two power control cabinets per chamber. The chambers have 6 zones each, and each power control cabinet controls 3 zones. In relation to the motor, the electromagnetic drive of rappers provides more options when choosing the way of setting the rappers, which directly affects the complexity of the power supply management equipment. The applied solutions in the software and energy part, after the reconstruction of the electromagnetic rappers drive in 2024, contributed to more reliable operation of both the rappers and the electrostatic precipitator as a whole.
