Best ppt on Presentation on Coal handling plant ... Strain gauge load cells work on the principle that the strain gauge(a planar resistor) deforms/stretches/contracts when the material of the load cells deforms appropriately.These values are extremely small and are relational to the stress and/or strain that the material load cell is undergoing ...
A fluid coupling (FC) or hydraulic coupling is a device used for transmitting power from one shaft to another shaft by means of acceleration and deceleration of a hydraulic fluid. It is based on hydro-kinetic principles and requires that the output speed be less than the input. This difference in speed is called slip.
The design requires the completion of the overall hardware design and software design of the power plant's coal transportation system to produce a system …
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
Working of In Line Magnetic Separator. Feeding of power supply to ILMS done before starting of conveyor belt.

The whole system has been designed and tested using G.E FANUC PLC with SCADA. In this paper an integrated solution of coal handling plant is given to meet the increasing production needs. The ...
A thermal power station is a power plant in which the prime mover is steam driven. Water when heated turns into steam which drives a steam turbine. After passing through the turbine, the steam is condensed in a condenser and recycled to where it was heated. [Rankine cycle] Coal is used as a fuel to heat water in a coal based thermal …
Pneumatic Load Cells. They also operate on the force-balance principle. The force is applied to one side of diaphragm of flexible material and balanced by pneumatic pressure on the other side. The counteracting pressure is proportional to the force and displayed on a pressure dial. Pneumatic load cells are often used to measure relatively …
4. What is the main characteristic of in plant coal handling system? a) It should be easy to handle. b) Should be simple in construction. c) Free from repetitive handling. d) Free from corrosion problems. Answer: Free from repetitive handling. 5. Why is it necessary to have a coal storage yard near the plant? a) To supply to other nearby …
Steam (Thermal) Power Plant. Coal and Ash circuit ; Pulverised coal from the storage area (called stack) is taken to the boiler by means of coal handling equipment such as belt conveyors, bucket elevators etc. Note A thermal power plant of 400 MW capacity requires 5000 to 6000 tonnes of coal per day. After the pulverised coal is burnt at 15000C to

In a coal based thermal power plant, the initial process in the power generation is "Coal Handling". So in this article i will discuss the overall processes carried out at a Coal Handling plant in a coal based thermal power generating station. The huge amount of coal is usually supplied through railways. A railway siding line is taken …
Bottom Ash – Ash generated below furnace of the thermal power plant is called the bottom ash. 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 …

The Coal Power Plant or Steam Power Plant has four major circuits by which the layout can be studied in detail. These are. 1. Coal and ash Circuit: This circuit consists of coal delivery, preparation of coal, handling of coal to the boiler furnace, ash handling and ash storage. The coal which is received from the mines are stored in coal storage.
2. Dead storage or outdoor storage • In this storage the coal received at the power plant is stored in dead storage in the form of piles laid directly on the ground. the coal stored has the tendency to combine with oxygen of air and during this process coal loss some of its heating value and ignition quality. • Due to oxidation the coal may ignite …
