SURVEILLANCE OF FLY ASH FLOW THROUGH THE FLY ASH FEED VALVE ON TRANSPORT PIPES IN THERMAL POWER FLY ASH SYSTEM

Abstract

The thermal power fly ash disposal system is designed to ensure the collection and treatment of waste from the thermal power plant incinerator including fly ash and wetted ash from the incinerator, for pre-reuse required treatment. When released into the environment. Accordingly, fly ash collection systems, dust filters and waste treatment are designed in ash waste systems. In this paper, some results of material flow characteristics through the ash feed valve to the transport pipeline in the fly ash disposal system are performed using numerical simulation tools. Accordingly, the material flow characteristics through the fly ash feed valve from the fly ash collection system to the fly ash transport pipeline to the fly ash silo are implemented. The simulation results of the material flow through the valve such as velocity distribution and pressure flow through the valve onto the conveying pipeline are essential basis for the design of the valve disc surface structure, reinforce and maintain the valve disc as well as offer efficient operation options for the system.
