The dust handling plant is associated with the ash handling plant but is considered as a separate layout problem. The dust is handled in its dry state throughout the plant by pneumatic air slides which remove dust from the economiser hoppers and precipitator hoppers. Consideration is also given to avoiding low trap points in boiler gas ducting to prevent any build-up of dust within the ducting
Layout of Ash handling system . Ash Handling System: Boilers burning pulverized coal (PC) have bottom furnaces. The large ash particles are collected under the furnace in a water-filled ash hopper, Fly ash is collected in dust collectors with either an electrostatic precipitator or a baghouse. A PC boiler generates approximately 80% fly ash and 20% bottom ash. Ash must be collected and

Wet Ash handling System The free falling Ash from boiler furnace is collected and stored in a ‘W’ shaped water impounded bottom ash hopper provided below boiler furnace for its periodic removal tw in a shift of eight (8) hours per unit. The Hot Ash from the furnace gets quenched as it enters into the water minimizing the clinker formation The mixture of Ash and Water (SLURRY) stored in
ASH HANDLING SYSTEMS. Unlike imported coal (which is of high calorific value at about 5000 Kcal/kg), Indian coal has lower calorific value at 3000 Kcal/kg. This increases the quantity of coal required per unit power generation. Secondly, Indian coal has high ash content (40 to 50%) which is also highly abrasive in nature. As a result, domestic coal based power plant is likely to produce 3 to 5
Title: Ash Handling Plant (AHP) : Power, Cement, Steel . Business Challenge: Ash handling system mainly design for the collection, handling and disposal of bottom ash and fly ash from ESP System to Silo area and operation of its associated systems i.e. ash water, instrument air, conveying air and fluidizing air system. To increasing avaiility, increasing efficiency, and controlling
A dilute phase system is provided for extraction of dry fly ash in the first stage, and for second stage, a dense phase conveying system is provided for transportation of dry fly ash to the main storage silos. Ducon provides complete turn key systems that are custom engineered based on plant layout, capcities and site conditions. .
25/02/2016· Ash Handling Plant. Posted on February 25, 2016 May 21, 2018 by Himanshu Ojha. 25 Feb. When the Coal combustion takes place in the boiler, some part of the coal remains unburnt and that un-burnt particles are called the Ash, which is approximately 26% to 40% of the total coal undergoing combustion. Basically this is nothing but the residual part of the coal. This ash will be extracted out in

Coal is the main fuel used in Thermal Power Plants
Place for ash handling plant for thermal power station should also be availe very near by. Very tall chimney of power station should not obstruct the traffics of air ships. Advantages and Disadvantages of Thermal Power Station Advantages: Economical for low initial cost other than any generating plant. Land required less than hydro power plant. Since coal is main fuel and its cost is quite
A coal preparation plant (CPP; also known as a coal handling and preparation plant (CHPP), coal handling plant, prep plant, tipple or wash plant) is a facility that washes coal of soil and rock, crushes it into graded sized chunks (sorting), stockpiles grades preparing it for transport to market, and more often than not, also loads coal into rail cars, barges, or ships.
