In a forced draught system, a blower is installed near the base of the boiler. This draught system is known as positive draught system or forced draught system because the pressure of air throughout the system is above atmospheric pressure and air is forced to flow through the system. The arrangement of the system is shown in figure. Force Draught

The plant cooling system uses mechanical-draft cooling towers with a circulating water temperature rise of 20°F. The condensers are evaluated as multi-flow units, one per each two-flow LP unit. 2.2 MATERIAL HANDLING The material handling equipment electrical loads include items such as intermittent rail car unloading, conveyors and crushers.

Bottom ash handling System. The bottom ash quantity is around 20% of the total Ash generation and there are mainly two types of bottom ash disposal systems. Dry Type Bottom Ash Disposal; Wet Ash Slurry Disposal; Dry Type Bottom Ash Disposal: First of all we will discuss about the Dry type bottom ash disposal system.

The ash is then carried by a high velocity air or steam to the point of delivery. Air leaving the ash separator is passed through filter to remove dust etc. So that the exhauster handles clean air which will protect the blades of the exhauster. Mechanical system. Figure shows a …

The value of bottom ash generated is around 20 % of total ash. Bottom ash is mostly coarse in nature hence it needs to be further crushed before being transported to ash handling system. Fly Ash – Around 80 % of ash generated in thermal power plant is fly ash. It is in form of very fine particles which is collected via economiser hopper, air ...

A second stage system - positive pressure system is employed to convey fly ash from ISH to main fly ash Silo(s). Vacuum system envisages conveying of dry fly ash from ash hoppers by vacuum pumps and collection in ISH. Each vacuum pump, dedicated to a stream, can convey both coarse and fine ash.

Ash handling systems may employ different forms of pneumatic ash conveying or mechanical ash conveyors. A typical ash handling system may employ vacuum pneumatic ash collection with ash conveying from several ash pick up stations and resulting in delivery to an ash storage silo for interim holding prior to load out for disposal or reuse.

Fly Ash is the major constituent of the ash generated from Pulverized and Fluidized bed Coalfired boilers. The Fly ash gets collected at various points, with most of it in ESP hoppers. One of the methods for handling Fly Ash is Wet system in which the ash is mixed with water to …

Why Ash Handling? Ash content of Indian coal used in power station is about 30 to 40 %. A typical 2000 MW station produce around 9000T to 12000T of ash per day. This huge amount of ash needs to be disposed off continuously. Necessary care to be taken for preventing pollution. Classification of Ash. Bottom Ash Wet System Wet System. Fly Ash. Dry ...

With hundreds of systems operating worldwide, maintenance for mechanical ash systems and components has grown to major importance. Ash Systems Maintenance has been formed to focus directly on this need. Drawing on the over forty years of design, operations and maintenance preceding it, ASM is uniquely qualified in these areas:

THERE ARE THREE MAIN KINDS OF ASH HANDLING SYSTEMS: (1) Hydraulic system (2) Pneumatic system (3) Mechanical system. CLASSIFICATION OF ASH HANDLING SYSTEMS: Hydraulic System: In this system, ash from the furnace grate falls into a system of water traveling at a high-pressure and is carried to the sumps. It is generally used in large power plants.

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. A Mechanical Ash Handling System is often the best choice for fluidized bed ash where headroom is restricted under ...

Mechanized ash handling systems developed as the size of coal fired boilers increased beyond the sizes permitting manual handling of large quantity of ash. In a coal based thermal power plant, huge amount of ash is generated which has to be disposed off continuously. Typically for a 2x500 MW plant based on Indian coal, the amount of ash ...
