diagrams, the general layout and operation of a pneumatic actuation system, a hydraulic actuation system and a mechanical handling system P9 describe, with the aid of diagrams, the general layout and operation of a steam power generation plant, a refrigeration system and an air conditioning system.
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
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.
Ash storage and disposal sites are guided by environmental regulations. Figure: Layout of ash collection and transportation . The sluice conveyor system is the most widely used for bottom ash handling, while the hydraulic vaccum conveyor (figure) is the most frequently used for fly systems. Figure: Layout of ash handling system.
Ash Handling Systems Ducon supplies both wet and dry type ash systems for power plants. Wet ash system is can be utilized for Bottom Ash handling with water impounded hopper and jet pumps for intermittent collected in economiser, primary air heater and secondary air heater hoppers drops continuously through suitable vertical pipe connections to the flushing connections provided
ASH HANDLING SYSTEM: Boilers burning pulverized coal (PC) have bottom furnaces. The large ash particles are collected under the furnace in a waterfilled 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.

#0183;#32;Requirement of Ash Handling System In Thermal Power Plants 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.

#0183;#32;ASH HANDLING SYSTEMS Hydraulic system Pneumatic system Mechanical system 7. HYDRAULIC SYSTEM : Ash from the furnace grate, falls into a system of water possessing high velocity and is carried to the sumps. It is generally used in large power plants. 8. 1. Hydraulic system : 1. Low Pressure Hydraulic System. Pressure Hydraulic System.
#0183;#32;DESIGN OF INPLANT COAL HANDLING SYSTEM POINTS TO REMEMBER : 1. Simple and sound, requiring minimum operations and transportation. 2. No double handling of coal in plant. 3. Handling unit should be centralized to facilitate inspection and maintenance. 4. Electric motors can be used as driver of mechanism. 5.
A hydraulic reservoir stores hydraulic fluid. This is a musthave component in any hydraulic system. All hydraulic reservoirs are open to the atmosphere except in the case of those used
Symbol Of Pump Used In Hydraulic System Circuit Diagram. 3. Hydraulic Motor . A hydraulic motor is a mechanical hydraulic actuator that converts hydraulic energy or hydraulic pressure into torque and angular displacement / rotation.

Hydraulic Ash Handling system 3. for coal handling plant of thermal power . but one of the main systems of thermal power plant is coal of coal handling plant is shown by block diagram. the coal flows through coal mills to more detailed A Review On Mechanical And Hydraulic System.
In a hydraulic system, pressure, applied to a contained fluid at any point, is transmitted undiminished. That pressurized fluid acts upon every part of the section of a containing vessel and creates force or power. Due to the use of this force, and depending on how its applied,
