8090 % Ash Stage C: 3 % Wet FA Handling System FA is collected from Air heater hopper, Eco hopper and ESP hopper In Flushing apparatus system ash is allowed to fall in flushing apparatus under gravitation Water jet in flushing apparatus carries away the ash to FA trench High pressure jets further carries it to FA sump Series pumping carries the ash slurry to FA pond ESP DEASHING ASH HANDLING SYSTEM WHAT IS ASH? We all know that after burning of coal in the furnace, the residual which we get in Bottom ash hopper, Economizer hoppers, Air pre heater hoppers, ESP hoppers and at chimney is known as ash Now cement industry has started using it as one of their raw material and ready to pay for it, therefore, now it will be appropriate to call ASH as bi product of Ash Handling System Scribdash handling system in thermal power plant an overview thermal power generation capacity of india capacity of thermal power plants in india aug 2008 77198 mw 2012 (estimated) mw ash generation 130 million tons (approx) challenges in ash disposalOverview on Ash Handling System Pump Boiler ScribdAn ash handling system consists of some subsystems such as bottom ash (BA), fly ash (ESP/air heater), ash water, and ash disposal systems The ash handling system may be dry (dry pneumatic conveying is more popular now on account of retention of original characteristics of fly ash and its utilization), semiautomatic wet, and a wet systemAsh Handling Plant an overview ScienceDirect TopicsAsh system adopts a dense phase pneumatic conveying system with positive pressure for ash handling Unitoperation The Turbine can be run with a fixed pressure OR sliding pressure mode When the boiler is running with low load or starting, sliding pressure is recommended to obtain a higher economic efficiency Boiler specification NO Item Specification Unit model660 MW Super Critical Unit Operation Experiences Scribd
Ash Handling System of a Thermal Power Plant
12 Requirement of Ash Handling System In Thermal Power Plant’s coal is generally used as fuel and hence the ash is produced as the byproduct of Combustion Ash generated in power plant is about 30 40% of total coal consumption and hence the system is required to handle Ash for its proper utilization or disposal With regulatory changes on the horizon, coalfired power plant operators are preparing for modifications in ash handling procedures A number of Ash Handling Options for CoalFired Power Plants Power Four years after more than one billion gallons of coal ash slurry spilled from a storage pond at the Kingston Power Plant in eastern Tennessee, environmental groups are still waiting for the UCoal Ash Handling Storage: Shifting Direction Power modern coal power plant, Super Critical Boilers, FBC Boilers, Turbines, Condensers, Steam Heat rate, Subsystems of thermal power plants –Fuel and ash handling, Draught system, Feed water treatment Binary Cycles and Cogeneration systems RANKINE CYCLE •Rankine cycle is a thermodynamic cycle on which the steam turbine works The line diagram is shown in fig Thermal ME6701 POWER PLANT ENGINEERING ASH DISPOSAL : 1 A large quantity of ash, is produced in steam power plants using coal 2 Ash produced in about 10 to 20% of the total coal burnt in the furnace 3 Handling of ash is a problem because ash coming out of the furnace is too hot, it is dusty and irritating to handle and is accompanied by some poisonous gases 4Ash handling system SlideShare
