MODERNIZATION OF THE DRAINAGE SYSTEM AND ASH SLURRY HANDLING SYSTEM IN TPP KOSTOLAC A

ABSTRACT
The paper describes the modernization of ash slurry drainage and handling from Units A1 and A2 devices for receiving, extinguishing and transporting bottom ash and fly ash from the boiler grate to silos and mass/volume process water sumps, with new technical solutions and experiences in exploitation. The main goal of the drainage system modernization and ash slurry handling system in TPP Kostolac A is to improve the system operation and to reduce the number of deadlocks during operation.
